Theme
A single page of themed Bootstrap elements, all in one place.
Code
User input
Use the <kbd> to indicate input that is typically entered via keyboard.
To switch directories, type cd followed by the name of the directory.
To edit settings, press ctrl + ,
To edit settings, press ctrl + ,
To switch directories, type <kbd>cd</kbd> followed by the name of the directory.<br>
To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd>Basic block
Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.
<p>Sample text here...</p>
<pre><p>Sample text here...</p></pre>You may optionally add the .pre-scrollable class, which will set a max-height of 350px and provide a y-axis scrollbar.
Forms
Basic example
Individual form controls automatically receive some global styling. All textual <input>, <textarea>, and <select> elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.
<form>
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email">
</div>
<div class="form-group">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" id="exampleInputFile">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Check me out
</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>Don't mix form groups with input groups
Do not mix form groups directly with input groups. Instead, nest the input group inside of the form group.
Inline form
Add .form-inline to your form (which doesn't have to be a <form>) for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.
May require custom widths
Inputs and selects have width: 100%; applied by default in Bootstrap. Within inline forms, we reset that to width: auto; so multiple controls can reside on the same line. Depending on your layout, additional custom widths may be required.
Always add labels
Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only class. There are further alternative methods of providing a label for assistive technologies, such as the aria-label, aria-labelledby or title attribute. If none of these is present, screen readers may resort to using the placeholder attribute, if present, but note that use of placeholder as a replacement for other labelling methods is not advised.
<form class="form-inline">
<div class="form-group">
<label for="exampleInputName2">Name</label>
<input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe">
</div>
<div class="form-group">
<label for="exampleInputEmail2">Email</label>
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="jane.doe@example.com">
</div>
<button type="submit" class="btn btn-default">Send invitation</button>
</form><form class="form-inline">
<div class="form-group">
<label class="sr-only" for="exampleInputEmail3">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail3" placeholder="Email">

<div class="form-group">
<label class="sr-only" for="exampleInputPassword3">Password</label>
<input type="password" class="form-control" id="exampleInputPassword3" placeholder="Password">

<input type="checkbox"> Remember me
</label>
</div>
<button type="submit" class="btn btn-default">Sign in</button>
</form><form class="form-inline">
<div class="form-group">
<label class="sr-only" for="exampleInputAmount">Amount (in dollars)</label>
<div class="input-group">
<div class="input-group-addon">$</div>
<input type="text" class="form-control" id="exampleInputAmount" placeholder="Amount">
<div class="input-group-addon">.00</div>
</div>
</div>
<button type="submit" class="btn btn-primary">Transfer cash</button>
</form>Horizontal form
Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form (which doesn't have to be a <form>). Doing so changes .form-groups to behave as grid rows, so no need for .row.
<form class="form-horizontal">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>Supported controls
Examples of standard form controls supported in an example form layout.
Inputs
Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.
Type declaration required
Inputs will only be fully styled if their type is properly declared.
<input type="text" class="form-control" placeholder="Text input">Input groups
To add integrated text or buttons before and/or after any text-based <input>, check out the input group component.
Textarea
Form control which supports multiple lines of text. Change rows attribute as necessary.
<textarea class="form-control" rows="3"></textarea>Checkboxes and radios
Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.
A checkbox or radio with the disabled attribute will be styled appropriately. To have the <label> for the checkbox or radio also display a "not-allowed" cursor when the user hovers over the label, add the .disabled class to your .radio, .radio-inline, .checkbox, .checkbox-inline, or <fieldset>.
Default (stacked)
<div class="checkbox">
<label>
<input type="checkbox" value="">
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="checkbox disabled">
<label>
<input type="checkbox" value="" disabled>
Option two is disabled
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two can be something else and selecting it will deselect option one
</label>
</div>
<div class="radio disabled">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios3" value="option3" disabled>
Option three is disabled
</label>
</div>Inline checkboxes and radios
Use the .checkbox-inline or .radio-inline classes on a series of checkboxes or radios for controls that appear on the same line.
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2"> 2
</label>
<label class="radio-inline">
<input type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3"> 3
</label>Checkboxes and radios without label text
Should you have no text within the <label>, the input is positioned as you'd expect. Currently only works on non-inline checkboxes and radios. Remember to still provide some form of label for assistive technologies (for instance, using aria-label).
<div class="checkbox">
<label>
<input type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
</label>
</div>Selects
Note that many native select menus—namely in Safari and Chrome—have rounded corners that cannot be modified via border-radius properties.
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>For <select> controls with the multiple attribute, multiple options are shown by default.
<select multiple class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>Static control
When you need to place plain text next to a form label within a form, use the .form-control-static class on a <p>.
<form class="form-horizontal">
<div class="form-group">
<label class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<p class="form-control-static">email@example.com</p>
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" placeholder="Password">
</div>
</div>
</form><form class="form-inline">
<div class="form-group">
<label class="sr-only">Email</label>
<p class="form-control-static">email@example.com</p>
</div>
<div class="form-group">
<label for="inputPassword2" class="sr-only">Password</label>
<input type="password" class="form-control" id="inputPassword2" placeholder="Password">
</div>
<button type="submit" class="btn btn-default">Confirm identity</button>
</form>Focus state
We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.
Demo :focus state
The above example input uses custom styles in our documentation to demonstrate the :focus state on a .form-control.
Disabled state
Add the disabled boolean attribute on an input to prevent user interactions. Disabled inputs appear lighter and add a not-allowed cursor.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>Disabled fieldsets
Add the disabled attribute to a <fieldset> to disable all the controls within the <fieldset> at once.
Caveat about link functionality of <a>
By default, browsers will treat all native form controls (<input>, <select> and <button> elements) inside a <fieldset disabled> as disabled, preventing both keyboard and mouse interactions on them. However, if your form also includes <a ... class="btn btn-*"> elements, these will only be given a style of pointer-events: none. As noted in the section about disabled state for buttons (and specifically in the sub-section for anchor elements), this CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11, and won't prevent keyboard users from being able to focus or activate these links. So to be safe, use custom JavaScript to disable such links.
Cross-browser compatibility
While Bootstrap will apply these styles in all browsers, Internet Explorer 11 and below don't fully support the disabled attribute on a <fieldset>. Use custom JavaScript to disable the fieldset in these browsers.
<form>
<fieldset disabled>
<div class="form-group">
<label for="disabledTextInput">Disabled input</label>
<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
</div>
<div class="form-group">
<label for="disabledSelect">Disabled select menu</label>
<select id="disabledSelect" class="form-control">
<option>Disabled select</option>
</select>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Can't check this
</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</fieldset>
</form>Readonly state
Add the readonly boolean attribute on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.
<input class="form-control" type="text" placeholder="Readonly input here…" readonly>Validation states
Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning, .has-error, or .has-success to the parent element. Any .control-label, .form-control, and .help-block within that element will receive the validation styles.
Conveying validation state to assistive technologies and colorblind users
Using these validation styles to denote the state of a form control only provides a visual, color-based indication, which will not be conveyed to users of assistive technologies - such as screen readers - or to colorblind users.
Ensure that an alternative indication of state is also provided. For instance, you can include a hint about state in the form control's <label> text itself (as is the case in the following code example), include a Glyphicon (with appropriate alternative text using the .sr-only class - see the Glyphicon examples), or by providing an additional help text block. Specifically for assistive technologies, invalid form controls can also be assigned an aria-invalid="true" attribute.
<div class="form-group has-success">
<label class="control-label" for="inputSuccess1">Input with success</label>
<input type="text" class="form-control" id="inputSuccess1">
</div>
<div class="form-group has-warning">
<label class="control-label" for="inputWarning1">Input with warning</label>
<input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
<label class="control-label" for="inputError1">Input with error</label>
<input type="text" class="form-control" id="inputError1">
</div>
<div class="has-success">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxSuccess" value="option1">
Checkbox with success
</label>
</div>
</div>
<div class="has-warning">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxWarning" value="option1">
Checkbox with warning
</label>
</div>
</div>
<div class="has-error">
<div class="checkbox">
<label>
<input type="checkbox" id="checkboxError" value="option1">
Checkbox with error
</label>
</div>
</div>With optional icons
You can also add optional feedback icons with the addition of .has-feedback and the right icon.
Feedback icons only work with textual <input class="form-control"> elements.
Icons, labels, and input groups
Manual positioning of feedback icons is required for inputs without a label and for input groups with an add-on on the right. You are strongly encouraged to provide labels for all inputs for accessibility reasons. If you wish to prevent labels from being displayed, hide them with the .sr-only class. If you must do without labels, adjust the top value of the feedback icon. For input groups, adjust the right value to an appropriate pixel value depending on the width of your addon.
Conveying the icon's meaning to assistive technologies
To ensure that assistive technologies – such as screen readers – correctly convey the meaning of an icon, additional hidden text should be included with the .sr-only class and explicitly associated with the form control it relates to using aria-describedby. Alternatively, ensure that the meaning (for instance, the fact that there is a warning for a particular text entry field) is conveyed in some other form, such as changing the text of the actual <label> associated with the form control.
Although the following examples already mention the validation state of their respective form controls in the <label> text itself, the above technique (using .sr-only text and aria-describedby) has been included for illustrative purposes.
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess2">Input with success</label>
<input type="text" class="form-control" id="inputSuccess2" aria-describedby="inputSuccess2Status">

If you use the .sr-only class to hide a form control's <label> (rather than using other labelling options, such as the aria-label attribute), Bootstrap will automatically adjust the position of the icon once it's been added.

</div>Control sizing
Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.
Height sizing
Create taller or shorter form controls that match button sizes.
<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">
<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>Horizontal form group sizes
Quickly size labels and form controls within .form-horizontal by adding .form-group-lg or .form-group-sm.
<form class="form-horizontal">
<div class="form-group form-group-lg">
<label class="col-sm-2 control-label" for="formGroupInputLarge">Large label</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="formGroupInputLarge" placeholder="Large input">
</div>
</div>
<div class="form-group form-group-sm">
<label class="col-sm-2 control-label" for="formGroupInputSmall">Small label</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="formGroupInputSmall" placeholder="Small input">
</div>
</div>
</form>Column sizing
Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.
<div class="row">
<div class="col-xs-2">
<input type="text" class="form-control" placeholder=".col-xs-2">
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder=".col-xs-3">
</div>
<div class="col-xs-4">
<input type="text" class="form-control" placeholder=".col-xs-4">
</div>
</div>Help text
Block level help text for form controls.
Associating help text with form controls
Help text should be explicitly associated with the form control it relates to using the aria-describedby attribute. This will ensure that assistive technologies – such as screen readers – will announce this help text when the user focuses or enters the control.
<label class="sr-only" for="inputHelpBlock">Input with help text</label>
<input type="text" id="inputHelpBlock" class="form-control" aria-describedby="helpBlock">
...
<span id="helpBlock" class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>Buttons
Button tags
Use the button classes on an <a>, <button>, or <input> element.
<a class="btn btn-default" href="#" role="button">Link</a>
<button class="btn btn-default" type="submit">Button</button>
<input class="btn btn-default" type="button" value="Input">
<input class="btn btn-default" type="submit" value="Submit">Context-specific usage
While button classes can be used on <a> and <button> elements, only <button> elements are supported within our nav and navbar components.
Links acting as buttons
If the <a> elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate role="button".
Cross-browser rendering
As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.
Among other things, there's a bug in Firefox <30 that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox.
Options
Use any of the available button classes to quickly create a styled button.
<!-- Standard button -->
<button type="button" class="btn btn-default">Default</button>
<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">Primary</button>
<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success">Success</button>
<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">Info</button>
<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning">Warning</button>
<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger">Danger</button>
<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">Link</button>Conveying meaning to assistive technologies
Using color to add meaning to a button only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (the visible text of the button), or is included through alternative means, such as additional text hidden with the .sr-only class.
Sizes
Fancy larger or smaller buttons? Add .btn-lg, .btn-sm, or .btn-xs for additional sizes.
<p>
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-default btn-lg">Large button</button>
</p>
<p>
<button type="button" class="btn btn-primary">Default button</button>
<button type="button" class="btn btn-default">Default button</button>
</p>
<p>
<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-default btn-sm">Small button</button>
</p>
<p>
<button type="button" class="btn btn-primary btn-xs">Extra small button</button>
<button type="button" class="btn btn-default btn-xs">Extra small button</button>
</p>Create block level buttons—those that span the full width of a parent— by adding .btn-block.
<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>Active state
Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. For <button> elements, this is done via :active. For <a> elements, it's done with .active. However, you may use .active on <button>s (and include the aria-pressed="true" attribute) should you need to replicate the active state programmatically.
Button element
No need to add :active as it's a pseudo-class, but if you need to force the same appearance, go ahead and add .active.
<button type="button" class="btn btn-primary btn-lg active">Primary button</button>
<button type="button" class="btn btn-default btn-lg active">Button</button>Anchor element
Add the .active class to <a> buttons.
<a href="#" class="btn btn-primary btn-lg active" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg active" role="button">Link</a>Disabled state
Make buttons look unclickable by fading them back with opacity.
Button element
Add the disabled attribute to <button> buttons.
<button type="button" class="btn btn-lg btn-primary" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-default btn-lg" disabled="disabled">Button</button>Cross-browser compatibility
If you add the disabled attribute to a <button>, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.
Anchor element
Add the .disabled class to <a> buttons.
<a href="#" class="btn btn-primary btn-lg disabled" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled" role="button">Link</a>
We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.
Link functionality caveat
This class uses pointer-events: none to try to disable the link functionality of <a>s, but that CSS property is not yet standardized and isn't fully supported in Opera 18 and below, or in Internet Explorer 11. In addition, even in browsers that do support pointer-events: none, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, use custom JavaScript to disable such links.
Cross-browser compatibility
Firefox persists form control states (disabledness and checkedness) across page loads. A workaround for this is to use autocomplete="off". See Mozilla bug #654072.
Stateful
Add data-loading-text="Loading..." to use a loading state on a button.
This feature is deprecated since v3.3.5 and will be removed in v4.
Use whichever state you like!
For the sake of this demonstration, we are using data-loading-text and $().button('loading'), but that's not the only state you can use. See more on this below in the $().button(string) documentation.
<button type="button" id="myButton" data-loading-text="Loading..." class="btn btn-primary" autocomplete="off">
Loading state
</button>
<script>
$('#myButton').on('click', function () {
var $btn = $(this).button('loading')
// business logic...
$btn.button('reset')
})
</script>Single toggle
Add data-toggle="button" to activate toggling on a single button.
Pre-toggled buttons need .active and aria-pressed="true"
For pre-toggled buttons, you must add the .active class and the aria-pressed="true" attribute to the button yourself.
<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false" autocomplete="off">
Single toggle
</button>Checkbox / Radio
Add data-toggle="buttons" to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.
Preselected options need .active
For preselected options, you must add the .active class to the input's label yourself.
Visual checked state only updated on click
If the checked state of a checkbox button is updated without firing a click event on the button (e.g. via <input type="reset"> or via setting the checked property of the input), you will need to toggle the .active class on the input's label yourself.
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="checkbox" autocomplete="off" checked> Checkbox 1 (pre-checked)
</label>
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off"> Checkbox 2
</label>
<label class="btn btn-primary">
<input type="checkbox" autocomplete="off"> Checkbox 3
</label>
</div><div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary active">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
</label>
</div>Images
Responsive images
Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%;, height: auto; and display: block; to the image so that it scales nicely to the parent element.
To center images which use the .img-responsive class, use .center-block instead of .text-center. See the helper classes section for more details about .center-block usage.
SVG images and IE 8-10
In Internet Explorer 8-10, SVG images with .img-responsive are disproportionately sized. To fix this, add width: 100% \9; where necessary. Bootstrap doesn't apply this automatically as it causes complications to other image formats.
<img src="..." class="img-responsive" alt="Responsive image">Image shapes
Add classes to an <img> element to easily style images in any project.
Cross-browser compatibility
Keep in mind that Internet Explorer 8 lacks support for rounded corners.
<img src="..." alt="..." class="img-rounded">
<img src="..." alt="..." class="img-circle">
<img src="..." alt="..." class="img-thumbnail">Dropdowns
Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.
Example
Wrap the dropdown's trigger and the dropdown menu within .dropdown, or another element that declares position: relative;. Then add the menu's HTML.
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>Dropdown menus can be changed to expand upwards (instead of downwards) by adding .dropup to the parent.
<div class="dropup">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropup
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu2">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>Alignment
By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add .dropdown-menu-right to a .dropdown-menu to right align the dropdown menu.
May require additional positioning
Dropdowns are automatically positioned via CSS within the normal flow of the document. This means dropdowns may be cropped by parents with certain overflow properties or appear out of bounds of the viewport. Address these issues on your own as they arise.
Deprecated .pull-right alignment
As of v3.1.0, we've deprecated .pull-right on dropdown menus. To right-align a menu, use .dropdown-menu-right. Right-aligned nav components in the navbar use a mixin version of this class to automatically align the menu. To override it, use .dropdown-menu-left.
<ul class="dropdown-menu dropdown-menu-right" aria-labelledby="dLabel">
...
</ul>Headers
Add a header to label sections of actions in any dropdown menu.
<ul class="dropdown-menu" aria-labelledby="dropdownMenu3">
...
<li class="dropdown-header">Dropdown header</li>
...
</ul>Divider
Add a divider to separate series of links in a dropdown menu.
<ul class="dropdown-menu" aria-labelledby="dropdownMenuDivider">
...
<li role="separator" class="divider"></li>
...
</ul>Disabled menu items
Add .disabled to a <li> in the dropdown to disable the link.
<ul class="dropdown-menu" aria-labelledby="dropdownMenu4">
<li><a href="#">Regular link</a></li>
<li class="disabled"><a href="#">Disabled link</a></li>
<li><a href="#">Another link</a></li>
</ul>Within a navbar
Within pills
Button groups
Group a series of buttons together on a single line with the button group. Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.
Tooltips & popovers in button groups require special setting
When using tooltips or popovers on elements within a .btn-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
Ensure correct role and provide a label
In order for assistive technologies – such as screen readers – to convey that a series of buttons is grouped, an appropriate role attribute needs to be provided. For button groups, this would be role="group", while toolbars should have a role="toolbar".
One exception are groups which only contain a single control (for instance the justified button groups with <button> elements) or a dropdown.
In addition, groups and toolbars should be given an explicit label, as most assistive technologies will otherwise not announce them, despite the presence of the correct role attribute. In the examples provided here, we use aria-label, but alternatives such as aria-labelledby can also be used.
Basic example
Wrap a series of buttons with .btn in .btn-group.
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">Left</button>
<button type="button" class="btn btn-default">Middle</button>
<button type="button" class="btn btn-default">Right</button>
</div>Button toolbar
Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.
<div class="btn-toolbar" role="toolbar" aria-label="...">
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
</div>Sizing
Instead of applying button sizing classes to every button in a group, just add .btn-group-* to each .btn-group, including when nesting multiple groups.
<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-xs" role="group" aria-label="...">...</div>Nesting
Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.
<div class="btn-group" role="group" aria-label="...">
<button type="button" class="btn btn-default">1</button>
<button type="button" class="btn btn-default">2</button>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Dropdown link</a></li>
<li><a href="#">Dropdown link</a></li>
</ul>
</div>
</div>Vertical variation
Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
<div class="btn-group-vertical" role="group" aria-label="...">
...
</div>Justified button groups
Make a group of buttons stretch at equal sizes to span the entire width of its parent. Also works with button dropdowns within the button group.
Handling borders
Due to the specific HTML and CSS used to justify buttons (namely display: table-cell), the borders between them are doubled. In regular button groups, margin-left: -1px is used to stack the borders instead of removing them. However, margin doesn't work with display: table-cell. As a result, depending on your customizations to Bootstrap, you may wish to remove or re-color the borders.
IE8 and borders
Internet Explorer 8 doesn't render borders on buttons in a justified button group, whether it's on <a> or <button> elements. To get around that, wrap each button in another .btn-group.
See #12476 for more information.
With <a> elements
Just wrap a series of .btns in .btn-group.btn-group-justified.
<div class="btn-group btn-group-justified" role="group" aria-label="...">
...
</div>Links acting as buttons
If the <a> elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate role="button".
With <button> elements
To use justified button groups with <button> elements, you must wrap each button in a button group. Most browsers don't properly apply our CSS for justification to <button> elements, but since we support button dropdowns, we can work around that.
<div class="btn-group btn-group-justified" role="group" aria-label="...">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Left</button>
</div>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Middle</button>
</div>
<div class="btn-group" role="group">
<button type="button" class="btn btn-default">Right</button>
</div>
</div>Button dropdowns
Use any button to trigger a dropdown menu by placing it within a .btn-group and providing the proper menu markup.
Plugin dependency
Button dropdowns require the dropdown plugin to be included in your version of Bootstrap.
Single button dropdowns
Turn a button into a dropdown toggle with some basic markup changes.
<!-- Single button -->
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Action <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>Split button dropdowns
Similarly, create split button dropdowns with the same markup changes, only with a separate button.
<!-- Split button -->
<div class="btn-group">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn btn-danger dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>Sizing
Button dropdowns work with buttons of all sizes.
<!-- Large button group -->
<div class="btn-group">
<button class="btn btn-default btn-lg dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Large button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
...
</ul>
</div>
<!-- Small button group -->
<div class="btn-group">
<button class="btn btn-default btn-sm dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Small button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
...
</ul>
</div>
<!-- Extra small button group -->
<div class="btn-group">
<button class="btn btn-default btn-xs dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Extra small button <span class="caret"></span>
</button>
<ul class="dropdown-menu">
...
</ul>
</div>Dropup variation
Trigger dropdown menus above elements by adding .dropup to the parent.
<div class="btn-group dropup">
<button type="button" class="btn btn-default">Dropup</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<!-- Dropdown menu links -->
</ul>
</div>Input groups
Extend form controls by adding text or buttons before, after, or on both sides of any text-based <input>. Use .input-group with an .input-group-addon to prepend or append elements to a single .form-control.
Textual <input>s only
Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.
Avoid using <textarea> elements here as their rows attribute will not be respected in some cases.
Tooltips & popovers in input groups require special setting
When using tooltips or popovers on elements within an .input-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
Don't mix with other components
Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.
Always add labels
Screen readers will have trouble with your forms if you don't include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.
The exact technique to be used (<label> elements hidden using the .sr-only class, or use of the aria-label, aria-labelledby, aria-describedby, title or placeholder attribute) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you're implementing. The examples in this section provide a few suggested, case-specific approaches.
Basic example
Place one add-on or button on either side of an input. You may also place one on both sides of an input.
We do not support multiple add-ons on a single side.
We do not support multiple form-controls in a single input group.
<div class="input-group">
<span class="input-group-addon" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
</div>
<div class="input-group">
<input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">
<span class="input-group-addon" id="basic-addon2">@example.com</span>
</div>
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-addon">.00</span>
</div>Sizing
Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no need for repeating the form control size classes on each element.
<div class="input-group input-group-lg">
<span class="input-group-addon" id="sizing-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon1">
</div>
<div class="input-group">
<span class="input-group-addon" id="sizing-addon2">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon2">
</div>
<div class="input-group input-group-sm">
<span class="input-group-addon" id="sizing-addon3">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon3">
</div>Checkboxes and radio addons
Place any checkbox or radio option within an input group's addon instead of text.
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-addon">
<input type="radio" aria-label="...">
</span>
<input type="text" class="form-control" aria-label="...">
</div><!-- /input-group -->
</div><!-- /.col-lg-6 -->
</div><!-- /.row -->Button addons
Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon, you'll need to use .input-group-btn to wrap the buttons. This is required due to default browser styles that cannot be overridden.
<div class="row">
<div class="col-lg-6">
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>

</div>
</div>Navs
Navs available in Bootstrap have shared markup, starting with the base .nav class, as well as shared states. Swap modifier classes to switch between each style.
Tabs
Note the .nav-tabs class requires the .nav base class.
<ul class="nav nav-tabs">
<li role="presentation" class="active"><a href="#">Home</a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages</a></li>
</ul>Pills
Take that same HTML, but use .nav-pills instead:
<ul class="nav nav-pills">
<li role="presentation" class="active"><a href="#">Home</a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages</a></li>
</ul>Pills are also vertically stackable. Just add .nav-stacked.
<ul class="nav nav-pills nav-stacked">
...
</ul>Justified
Easily make tabs or pills equal widths of their parent at screens wider than 768px with .nav-justified. On smaller screens, the nav links are stacked.
Justified navbar nav links are currently not supported.
<ul class="nav nav-tabs nav-justified">
...
</ul>
<ul class="nav nav-pills nav-justified">
...
</ul>Disabled links
For any nav component (tabs or pills), add .disabled for gray links and no hover effects.
<ul class="nav nav-pills">
...
<li role="presentation" class="disabled"><a href="#">Disabled link</a></li>
...
</ul>Using dropdowns
Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.
Tabs with dropdowns
<ul class="nav nav-tabs">
...
<li role="presentation" class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">

</ul>Navbar
Default navbar
Navbars are responsive meta components that serve as navigation headers for your application or site. They begin collapsed (and are toggleable) in mobile views and become horizontal as the available viewport width increases.
Justified navbar nav links are currently not supported.
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>

<li><a href="#">Separated link</a></li>
</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>Brand image
Replace the navbar brand with your own image by swapping the text for an <img>. Since the .navbar-brand has its own padding and height, you may need to override some CSS depending on your image.
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="#">
<img alt="Brand" src="...">
</a>
</div>
</div>
</nav>Forms
Place form content within .navbar-form for proper vertical alignment and collapsed behavior in narrow viewports. Use the alignment options to decide where it resides within the navbar content.
As a heads up, .navbar-form shares much of its code with .form-inline via mixin. Some form controls, like input groups, may require fixed widths to be show up properly within a navbar.
<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>Buttons
Add the .navbar-btn class to <button> elements not residing in a <form> to vertically center them in the navbar.
<button type="button" class="btn btn-default navbar-btn">Sign in</button>Text
Wrap strings of text in an element with .navbar-text, usually on a <p> tag for proper leading and color.
<p class="navbar-text">Signed in as Mark Otto</p>Non-nav links
For folks using standard links that are not within the regular navbar navigation component, use the .navbar-link class to add the proper colors for the default and inverse navbar options.
<p class="navbar-text navbar-right">Signed in as <a href="#" class="navbar-link">Mark Otto</a></p>Component alignment
Align nav links, forms, buttons, or text, using the .navbar-left or .navbar-right utility classes. Both classes will add a CSS float in the specified direction. For example, to align nav links, put them in a separate <ul> with the respective utility class applied.
These classes are mixin-ed versions of .pull-left and .pull-right, but they're scoped to media queries for easier handling of navbar components across device sizes.
Fixed to top
Add .navbar-fixed-top and include a .container or .container-fluid to center and pad navbar content.
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container">
...
</div>
</nav>Fixed to bottom
Add .navbar-fixed-bottom and include a .container or .container-fluid to center and pad navbar content.
<nav class="navbar navbar-default navbar-fixed-bottom">
<div class="container">
...
</div>
</nav>Static top
Create a full-width navbar that scrolls away with the page by adding .navbar-static-top and include a .container or .container-fluid to center and pad navbar content.
Unlike the .navbar-fixed-* classes, you do not need to change any padding on the body.
<nav class="navbar navbar-default navbar-static-top">
<div class="container">
...
</div>
</nav>Inverted navbar
Modify the look of the navbar by adding .navbar-inverse.
<nav class="navbar navbar-inverse">
...
</nav>Breadcrumbs
Indicate the current page's location within a navigational hierarchy.
Separators are automatically added in CSS through :before and content.
<ol class="breadcrumb">
<li><a href="#">Home</a></li>
<li><a href="#">Library</a></li>
<li class="active">Data</li>
</ol>Pagination
Provide pagination links for your site or app with the multi-page pagination component, or the simpler pager alternative.
Default pagination
Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.
<nav>
<ul class="pagination">
<li>
<a href="#" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
<li><a href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
<li><a href="#">5</a></li>
<li>
<a href="#" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
</li>
</ul>
</nav>Disabled and active states
Links are customizable for different circumstances. Use .disabled for unclickable links and .active to indicate the current page.
<nav>
<ul class="pagination">
<li class="disabled"><a href="#" aria-label="Previous"><span aria-hidden="true">«</span></a></li>
<li class="active"><a href="#">1 <span class="sr-only">(current)</span></a></li>
...
</ul>
</nav>You can optionally swap out active or disabled anchors for <span>, or omit the anchor in the case of the previous/next arrows, to remove click functionality while retaining intended styles.
<nav>
<ul class="pagination">
<li class="disabled">
<span>
<span aria-hidden="true">«</span>
</span>
</li>
<li class="active">
<span>1 <span class="sr-only">(current)</span></span>
</li>
...
</ul>
</nav>Sizing
Fancy larger or smaller pagination? Add .pagination-lg or .pagination-sm for additional sizes.
<nav><ul class="pagination pagination-lg">...</ul></nav>
<nav><ul class="pagination">...</ul></nav>
<nav><ul class="pagination pagination-sm">...</ul></nav>Pager
Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.
Default example
By default, the pager centers links.
<nav>
<ul class="pager">
<li><a href="#">Previous</a></li>
<li><a href="#">Next</a></li>
</ul>
</nav>Aligned links
Alternatively, you can align each link to the sides:
<nav>
<ul class="pager">
<li class="previous"><a href="#"><span aria-hidden="true">←</span> Older</a></li>
<li class="next"><a href="#">Newer <span aria-hidden="true">→</span></a></li>
</ul>
</nav>Optional disabled state
Pager links also use the general .disabled utility class from the pagination.
<nav>
<ul class="pager">
<li class="previous disabled"><a href="#"><span aria-hidden="true">←</span> Older</a></li>
<li class="next"><a href="#">Newer <span aria-hidden="true">→</span></a></li>
</ul>
</nav>Labels
Example
Example heading New
Example heading New
Example heading New
Example heading New
Example heading New
Example heading New
<h3>Example heading <span class="label label-default">New</span></h3>Available variations
Add any of the below mentioned modifier classes to change the appearance of a label.
Default
Primary
Success
Info
Warning
Danger
<span class="label label-default">Default</span>
<span class="label label-primary">Primary</span>
<span class="label label-success">Success</span>
<span class="label label-info">Info</span>
<span class="label label-warning">Warning</span>
<span class="label label-danger">Danger</span>Have tons of labels?
Rendering problems can arise when you have dozens of inline labels within a narrow container, each containing its own inline-block element (like an icon). The way around this is setting display: inline-block;. For context and an example, see #13219.
Badges
Easily highlight new or unread items by adding a <span class="badge"> to links, Bootstrap navs, and more.
<a href="#">Inbox <span class="badge">42</span></a>
<button class="btn btn-primary" type="button">
Messages <span class="badge">4</span>
</button>Self collapsing
When there are no new or unread items, badges will simply collapse (via CSS's :empty selector) provided no content exists within.
Cross-browser compatibility
Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty selector.
Adapts to active nav states
Built-in styles are included for placing badges in active states in pill navigations.
<ul class="nav nav-pills" role="tablist">
<li role="presentation" class="active"><a href="#">Home <span class="badge">42</span></a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages <span class="badge">3</span></a></li>
</ul>Jumbotron
A lightweight, flexible component that can optionally extend the entire viewport to showcase key content on your site.
Hello, world!
This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.
<div class="jumbotron">
<h1>Hello, world!</h1>
<p>...</p>
<p><a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a></p>
</div>To make the jumbotron full width, and without rounded corners, place it outside all .containers and instead add a .container within.
<div class="jumbotron">
<div class="container">
...
</div>
</div>Thumbnails
Extend Bootstrap's grid system with the thumbnail component to easily display grids of images, videos, text, and more.
If you're looking for Pinterest-like presentation of thumbnails of varying heights and/or widths, you'll need to use a third-party plugin such as Masonry, Isotope, or Salvattore.
Default example
By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.
<div class="row">
<div class="col-xs-6 col-md-3">
<a href="#" class="thumbnail">
<img src="..." alt="...">
</a>
</div>
...
</div>Custom content
With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.
<div class="row">
<div class="col-sm-6 col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<h3>Thumbnail label</h3>
<p>...</p>
<p><a href="#" class="btn btn-primary" role="button">Button</a> <a href="#" class="btn btn-default" role="button">Button</a></p>
</div>
</div>
</div>
</div>Alerts
Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.
Examples
Wrap any text and an optional dismiss button in .alert and one of the four contextual classes (e.g., .alert-success) for basic alert messages.
No default class
Alerts don't have default classes, only base and modifier classes. A default gray alert doesn't make too much sense, so you're required to specify a type via contextual class. Choose from success, info, warning, or danger.
Well done! You successfully read this important alert message.
Heads up! This alert needs your attention, but it's not super important.
Warning! Better check yourself, you're not looking too good.
Oh snap! Change a few things up and try submitting again.
<div class="alert alert-success" role="alert">...</div>
<div class="alert alert-info" role="alert">...</div>
<div class="alert alert-warning" role="alert">...</div>
<div class="alert alert-danger" role="alert">...</div>Dismissible alerts
Build on any alert by adding an optional .alert-dismissible and close button.
Requires JavaScript alert plugin
For fully functioning, dismissible alerts, you must use the alerts JavaScript plugin.
Warning! Better check yourself, you're not looking too good.
<div class="alert alert-warning alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">×</span></button>
<strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>Ensure proper behavior across all devices
Be sure to use the <button> element with the data-dismiss="alert" data attribute.
Links in alerts
Use the .alert-link utility class to quickly provide matching colored links within any alert.
Well done! You successfully read this important alert message.
Heads up! This alert needs your attention, but it's not super important.
Warning! Better check yourself, you're not looking too good.
Oh snap! Change a few things up and try submitting again.
<div class="alert alert-success" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-info" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-warning" role="alert">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-danger" role="alert">
<a href="#" class="alert-link">...</a>
</div>Progress bars
Provide up-to-date feedback on the progress of a workflow or action with simple yet flexible progress bars.
Cross-browser compatibility
Progress bars use CSS3 transitions and animations to achieve some of their effects. These features are not supported in Internet Explorer 9 and below or older versions of Firefox. Opera 12 does not support animations.
Basic example
Default progress bar.
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
<span class="sr-only">60% Complete</span>
</div>
</div>With label
Remove the <span> with .sr-only class from within the progress bar to show a visible percentage.
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
60%
</div>
</div>To ensure that the label text remains legible even for low percentages, consider adding a min-width to the progress bar.
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em;">
0%
</div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="2" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em; width: 2%;">
2%
</div>
</div>Contextual alternatives
Progress bars use some of the same button and alert classes for consistent styles.
<div class="progress">
<div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%">
<span class="sr-only">40% Complete (success)</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
<span class="sr-only">20% Complete</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%">

</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%">
<span class="sr-only">80% Complete (danger)</span>
</div>
</div>Striped
Uses a gradient to create a striped effect. Not available in IE9 and below.
<div class="progress">
<div class="progress-bar progress-bar-success progress-bar-striped" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%">
<span class="sr-only">40% Complete (success)</span>

</div>
<div class="progress">
<div class="progress-bar progress-bar-info progress-bar-striped" role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
<span class="sr-only">20% Complete</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-warning progress-bar-striped" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%">
<span class="sr-only">60% Complete (warning)</span>
</div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-danger progress-bar-striped" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%">
<span class="sr-only">80% Complete (danger)</span>
</div>
</div>Animated
Add .active to .progress-bar-striped to animate the stripes right to left. Not available in IE9 and below.
<div class="progress">
<div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="45" aria-valuemin="0" aria-valuemax="100" style="width: 45%">
<span class="sr-only">45% Complete</span>
</div>
</div>Stacked
Place multiple bars into the same .progress to stack them.
<div class="progress">
<div class="progress-bar progress-bar-success" style="width: 35%">
<span class="sr-only">35% Complete (success)</span>
</div>
<div class="progress-bar progress-bar-warning progress-bar-striped" style="width: 20%">
<span class="sr-only">20% Complete (warning)</span>
</div>
<div class="progress-bar progress-bar-danger" style="width: 10%">
<span class="sr-only">10% Complete (danger)</span>
</div>
</div>List group
List groups are a flexible and powerful component for displaying not only simple lists of elements, but complex ones with custom content.
Basic example
The most basic list group is simply an unordered list with list items, and the proper classes. Build upon it with the options that follow, or your own CSS as needed.
- Cras justo odio
- Dapibus ac facilisis in
- Morbi leo risus
- Porta ac consectetur ac
- Vestibulum at eros
<ul class="list-group">
<li class="list-group-item">Cras justo odio</li>
<li class="list-group-item">Dapibus ac facilisis in</li>
<li class="list-group-item">Morbi leo risus</li>
<li class="list-group-item">Porta ac consectetur ac</li>
<li class="list-group-item">Vestibulum at eros</li>
</ul>Badges
Add the badges component to any list group item and it will automatically be positioned on the right.
- 14 Cras justo odio
- 2 Dapibus ac facilisis in
- 1 Morbi leo risus
<ul class="list-group">
<li class="list-group-item">
<span class="badge">14</span>
Cras justo odio
</li>
</ul>Linked items
Linkify list group items by using anchor tags instead of list items (that also means a parent <div> instead of an <ul>). No need for individual parents around each element.
<div class="list-group">
<a href="#" class="list-group-item active">
Cras justo odio
</a>
<a href="#" class="list-group-item">Dapibus ac facilisis in</a>
<a href="#" class="list-group-item">Morbi leo risus</a>
<a href="#" class="list-group-item">Porta ac consectetur ac</a>
<a href="#" class="list-group-item">Vestibulum at eros</a>
</div>Button items
List group items may be buttons instead of list items (that also means a parent <div> instead of an <ul>). No need for individual parents around each element. Don't use the standard .btn classes here.
<div class="list-group">
<button type="button" class="list-group-item">Cras justo odio</button>
<button type="button" class="list-group-item">Dapibus ac facilisis in</button>
<button type="button" class="list-group-item">Morbi leo risus</button>
<button type="button" class="list-group-item">Porta ac consectetur ac</button>
<button type="button" class="list-group-item">Vestibulum at eros</button>
</div>Disabled items
Add .disabled to a .list-group-item to gray it out to appear disabled.
<div class="list-group">
<a href="#" class="list-group-item disabled">
Cras justo odio
</a>
<a href="#" class="list-group-item">Dapibus ac facilisis in</a>
<a href="#" class="list-group-item">Morbi leo risus</a>
<a href="#" class="list-group-item">Porta ac consectetur ac</a>
<a href="#" class="list-group-item">Vestibulum at eros</a>
</div>Contextual classes
Use contextual classes to style list items, default or linked. Also includes .active state.
- Dapibus ac facilisis in
- Cras sit amet nibh libero
- Porta ac consectetur ac
- Vestibulum at eros
<ul class="list-group">
<li class="list-group-item list-group-item-success">Dapibus ac facilisis in</li>
<li class="list-group-item list-group-item-info">Cras sit amet nibh libero</li>
<li class="list-group-item list-group-item-warning">Porta ac consectetur ac</li>
<li class="list-group-item list-group-item-danger">Vestibulum at eros</li>
</ul>
<div class="list-group">
<a href="#" class="list-group-item list-group-item-success">Dapibus ac facilisis in</a>
<a href="#" class="list-group-item list-group-item-info">Cras sit amet nibh libero</a>
<a href="#" class="list-group-item list-group-item-warning">Porta ac consectetur ac</a>
<a href="#" class="list-group-item list-group-item-danger">Vestibulum at eros</a>
</div>Custom content
Add nearly any HTML within, even for linked list groups like the one below.
List group item heading
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
List group item heading
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
List group item heading
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
<div class="list-group">
<a href="#" class="list-group-item active">
<h4 class="list-group-item-heading">List group item heading</h4>
<p class="list-group-item-text">...</p>
</a>
</div>Panels
While not always necessary, sometimes you need to put your DOM in a box. For those situations, try the panel component.
Basic example
By default, all the .panel does is apply some basic border and padding to contain some content.
Basic panel example
<div class="panel panel-default">
<div class="panel-body">
Basic panel example
</div>
</div>Panel with heading
Easily add a heading container to your panel with .panel-heading. You may also include any <h1>-<h6> with a .panel-title class to add a pre-styled heading.
For proper link coloring, be sure to place links in headings within .panel-title.
Panel heading without title

</div>Panel with footer
Wrap buttons or secondary text in .panel-footer. Note that panel footers do not inherit colors and borders when using contextual variations as they are not meant to be in the foreground.
Panel content
<div class="panel panel-default">
<div class="panel-body">

<div class="panel-footer">Panel footer</div>
</div>Contextual alternatives
Like other components, easily make a panel more meaningful to a particular context by adding any of the contextual state classes.

<div class="panel panel-warning">...</div>
<div class="panel panel-danger">...</div>With tables
Add any non-bordered .table within a panel for a seamless design. If there is a .panel-body, we add an extra border to the top of the table for separation.
Panel heading
Some default panel content here. Nulla vitae elit libero, a pharetra augue. Aenean lacinia bibendum nulla sed consectetur. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Nullam id dolor id nibh ultricies vehicula ut id elit.

<div class="panel-heading">Panel heading</div>
<div class="panel-body">

</div>
<!-- Table -->
<table class="table">

</table>
</div>If there is no panel body, the component moves from panel header to table without interruption.

</ul>
</div>Wells
Default well
Use the well as a simple effect on an element to give it an inset effect.
Look, I'm in a well!
<div class="well">...</div>Optional classes
Control padding and rounded corners with two optional modifier classes.
Look, I'm in a large well!
<div class="well well-lg">...</div>
Look, I'm in a small well!
<div class="well well-sm">...</div>Togglable tabs tab.js
Example tabs
Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus. Nested tabs are not supported.

Extends tabbed navigation
This plugin extends the tabbed navigation component to add tabbable areas.
Usage
Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
$('#myTabs a').click(function (e) {
e.preventDefault()
$(this).tab('show')
})You can activate individual tabs in several ways:
$('#myTabs a[href="#profile"]').tab('show') // Select tab by name
$('#myTabs a:first').tab('show') // Select first tab
$('#myTabs a:last').tab('show') // Select last tab
$('#myTabs li:eq(2) a').tab('show') // Select third tab (0-indexed)Markup
You can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling, while adding the nav and nav-pills classes will apply pill styling.
<div>
<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">

</div>Methods
$().tab
Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM. In the above examples, the tabs are the <a>s with data-toggle="tab" attributes.
.tab('show')
Selects the given tab and shows its associated content. Any other tab that was previously selected becomes unselected and its associated content is hidden.
$('#someTab').tab('show')Events
When showing a new tab, the events fire in the following order:
hide.bs.tab(on the current active tab)show.bs.tab(on the to-be-shown tab)hidden.bs.tab(on the previous active tab, the same one as for thehide.bs.tabevent)shown.bs.tab(on the newly-active just-shown tab, the same one as for theshow.bs.tabevent)
If no tab was already active, then the hide.bs.tab and hidden.bs.tab events will not be fired.
| Event Type | Description |
|---|---|
| show.bs.tab | This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
| shown.bs.tab | This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
| hide.bs.tab | This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use event.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively. |
| hidden.bs.tab | This event fires after a new tab is shown (and thus the previous active tab is hidden). Use event.target and event.relatedTarget to target the previous active tab and the new active tab, respectively. |
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.target // newly activated tab
e.relatedTarget // previous active tab
})Tooltips tooltip.js
Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.
Tooltips with zero-length titles are never displayed.
Examples
Hover over the links below to see tooltips:
Tight pants next level keffiyeh you probably haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown. Farm-to-table seitan, mcsweeney's fixie sustainable quinoa 8-bit american apparel have a terry richardson vinyl chambray. Beard stumptown, cardigans banh mi lomo thundercats.

Static tooltip
Four options are available: top, right, bottom, and left aligned.
Tooltip on the left
Tooltip on the top
Tooltip on the bottom
Tooltip on the right
Four directions
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
One way to initialize all tooltips on a page would be to select them by their data-toggle attribute:
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})Usage
The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
$('#example').tooltip(options)Markup
The required markup for a tooltip is only a data attribute and title on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).
<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
<!-- Generated markup by the plugin -->
<div class="tooltip top" role="tooltip">
<div class="tooltip-arrow"></div>
<div class="tooltip-inner">
Some tooltip text!
</div>
</div>Multiple-line links
Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
Tooltips in button groups and input groups require special setting
When using tooltips on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).
Accessible tooltips for keyboard and assistive technology users
For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a tabindex="0" attribute.
Tooltips on disabled elements require wrapper elements
To add a tooltip to a disabled or .disabled element, put the element inside of a <div> and apply the tooltip to that <div> instead.
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".
| Name | Type | Default | Description |
|---|---|---|---|
| animation | boolean | true | Apply a CSS fade transition to the tooltip |
| container | string | false | false |

Data attributes for individual tooltips
Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.
Methods
$().tooltip(options)
Attaches a tooltip handler to an element collection.
.tooltip('show')
Reveals an element's tooltip. Returns to the caller before the tooltip has actually been shown (i.e. before the shown.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.
$('#element').tooltip('show').tooltip('hide')
Hides an element's tooltip. Returns to the caller before the tooltip has actually been hidden (i.e. before the hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$('#element').tooltip('hide').tooltip('toggle')
Toggles an element's tooltip. Returns to the caller before the tooltip has actually been shown or hidden (i.e. before the shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$('#element').tooltip('toggle').tooltip('destroy')
Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$('#element').tooltip('destroy')Events
| Event Type | Description |
|---|---|
| show.bs.tooltip | This event fires immediately when the show instance method is called. |
| shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.tooltip | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.tooltip | This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete). |
| inserted.bs.tooltip | This event is fired after the show.bs.tooltip event when the tooltip template has been added to the DOM. |
$('#myTooltip').on('hidden.bs.tooltip', function () {
// do something…
})Popovers popover.js
Add small overlays of content, like those on the iPad, to any element for housing secondary information.
Popovers whose both title and content are zero-length are never displayed.

Make expand/collapse controls accessible
Be sure to add aria-expanded to the control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of aria-expanded="false". If you've set the collapsible element to be open by default using the in class, set aria-expanded="true" on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.
Additionally, if your control element is targetting a single collapsible element – i.e. the data-target attribute is pointing to an id selector – you may add an additional aria-controls attribute to the control element, containing the id of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
.collapsehides the content.collapse.inshows the content.collapsingis added when the transition starts, and removed when it finishes
These classes can be found in component-animations.less.
Via data attributes
Just add data-toggle="collapse" and a data-target to the element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you'd like it to default open, add the additional class in.
To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.
Via JavaScript
Enable manually with:
$('.collapse').collapse()Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-parent="".
| Name | type | default | description |
|---|---|---|---|
| parent | selector | false | If a selector is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the panel class) |
| toggle | boolean | true | Toggles the collapsible element on invocation |
Methods
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object.
$('#myCollapsible').collapse({
toggle: false
}).collapse('toggle')
Toggles a collapsible element to shown or hidden.
.collapse('show')
Shows a collapsible element.
.collapse('hide')
Hides a collapsible element.
Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
| Event Type | Description |
|---|---|
| show.bs.collapse | This event fires immediately when the show instance method is called. |
| shown.bs.collapse | This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.collapse |
This event is fired immediately when the hide method has been called.
|
| hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete). |
$('#myCollapsible').on('hidden.bs.collapse', function () {
// do something…
})Carousel carousel.js
A slideshow component for cycling through elements, like a carousel. Nested carousels are not supported.
Examples
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
<div class="item">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
...
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>Accessibility issue
The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
Transition animations not supported in Internet Explorer 8 & 9
Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
Initial active element required
The .active class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
Optional captions
Add captions to your slides easily with the .carousel-caption element within any .item. Place just about any optional HTML within there and it will be automatically aligned and formatted.
<div class="item">
<img src="..." alt="...">
<div class="carousel-caption">
<h3>...</h3>
<p>...</p>
</div>
</div>Usage
Multiple carousels
Carousels require the use of an id on the outermost container (the .carousel) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's id, be sure to update the relevant controls.
Via data attributes
Use data attributes to easily control the position of the carousel. data-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, use data-slide-to to pass a raw slide index to the carousel data-slide-to="2", which shifts the slide position to a particular index beginning with 0.
The data-ride="carousel" attribute is used to mark a carousel as animating starting at page load. It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.
Via JavaScript
Call carousel manually with:
$('.carousel').carousel()Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-interval="".
| Name | type | default | description |
|---|---|---|---|
| interval | number | 5000 | The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle. |
| pause | string | "hover" | Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave. |
| wrap | boolean | true | Whether the carousel should cycle continuously or have hard stops. |
| keyboard | boolean | true | Whether the carousel should react to keyboard events. |

Events
Bootstrap's carousel class exposes two events for hooking into carousel functionality.
Both events have the following additional properties:
direction: The direction in which the carousel is sliding (either"left"or"right").relatedTarget: The DOM element that is being slid into place as the active item.
All carousel events are fired at the carousel itself (i.e. at the <div class="carousel">).
| Event Type | Description |
|---|---|
| slide.bs.carousel | This event fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$('#myCarousel').on('slide.bs.carousel', function () {
// do something…
})
