Overview
Individual or compiled
Plugins can be included individually (using Bootstrap’s individual *.js
files), or all at once (using bootstrap.js
or the minified bootstrap.min.js
).
Do not attempt to include both.
Both bootstrap.js
and bootstrap.min.js
contain all plugins in a single file.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files). Consult our bower.json
to see which versions of jQuery are supported.
Data attributes
You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap’s first-class API and should be your first consideration when using a plugin.
That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with data-api
. This looks like this:
$(document).off('.data-api')
Alternatively, to target a specific plugin, just include the plugin’s name as a namespace along with the data-api namespace like this:
$(document).off('.alert.data-api')
Programmatic API
We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
$('.btn.danger').button('toggle').addClass('fat')
All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
$('#myModal').modal() // initialized with defaults
$('#myModal').modal({ keyboard: false }) // initialized with no keyboard
$('#myModal').modal('show') // initializes and invokes show immediately</p>
Each plugin also exposes its raw constructor on a Constructor
property: $.fn.popover.Constructor
. If you’d like to get a particular plugin instance, retrieve it directly from an element: $('[rel=popover]').data('popover')
.
No conflict
Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call .noConflict
on the plugin you wish to revert the value of.
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality
Events
Bootstrap provides custom events for most plugin’s unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show
) is triggered at the start of an event, and its past participle form (ex. shown
) is trigger on the completion of an action.
As of 3.0.0, all Bootstrap events are namespaced.
All infinitive events provide preventDefault
functionality. This provides the ability to stop the execution of an action before it starts.
$('#myModal').on('show.bs.modal', function (e) {
if (!data) return e.preventDefault() // stops modal from being shown
})
Third-party libraries
Bootstrap does not officially support third-party JavaScript libraries like Prototype or jQuery UI. Despite .noConflict
and namespaced events, there may be compatibility problems that you need to fix on your own. Ask on the mailing list if you need help.
Transitions transition.js
About transitions
For simple transition effects, include transition.js
once alongside the other JS files. If you’re using the compiled (or minified) bootstrap.js
, there is no need to include this—it’s already there.
What’s inside
Transition.js is a basic helper for transitionEnd
events as well as a CSS transition emulator. It’s used by the other plugins to check for CSS transition support and to catch hanging transitions.
Modals modal.js
Examples
Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
Overlapping modals not supported
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
Mobile device caveats
There are some caveats regarding using modals on mobile devices. See our browser support docs for details.
Static example
A rendered modal with header, body, and set of actions in the footer.
<div class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
Live demo
Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.
<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
Make modals accessible
Be sure to add role="dialog"
to .modal
, aria-labelledby="myModalLabel"
attribute to reference the modal title, and aria-hidden="true"
to tell assistive technologies to skip the modal’s DOM elements.
Additionally, you may give a description of your modal dialog with aria-describedby
on .modal
.
Usage
The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .model-open
to the <body>
to override default scrolling behavior and generates a .modal-backdrop
to provide a click area for dismissing shown modals when clicking outside the modal.
Via data attributes
Activate a modal without writing JavaScript. Set data-toggle="modal"
on a controller element, like a button, along with a data-target="#foo"
or href="#foo"
to target a specific modal to toggle.
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
Via JavaScript
Call a modal with id myModal
with a single line of JavaScript:
$('#myModal').modal(options)
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-
, as in data-backdrop=""
.
Name | type | default | description |
---|---|---|---|
backdrop | boolean or the string 'static' |
true | Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn’t close the modal on click. |
keyboard | boolean | true | Closes the modal when escape key is pressed |
show | boolean | true | Shows the modal when initialized. |
remote | path | false | If a remote URL is provided, content will be loaded via jQuery’s
|
Methods
.modal(options)
Activates your content as a modal. Accepts an optional options object
.
$('#myModal').modal({
keyboard: false
})
.modal(‘toggle’)
Manually toggles a modal. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal
or hidden.bs.modal
event occurs).
$('#myModal').modal('toggle')
.modal(‘show’)
Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal
event occurs).
$('#myModal').modal('show')
.modal(‘hide’)
Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal
event occurs).
$('#myModal').modal('hide')
Events
Bootstrap’s modal class exposes a few events for hooking into modal functionality.
Event Type | Description |
---|---|
show.bs.modal | This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event. |
shown.bs.modal | This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event. |
hide.bs.modal | This event is fired immediately when the hide instance method has been called. |
hidden.bs.modal | This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete). |
$('#myModal').on('hidden.bs.modal', function (e) {
// do something...
})
Dropdowns dropdown.js
Examples
Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.
Within a navbar
Within tabs
Usage
Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the .open
class on the parent list item. When opened, the plugin also adds .dropdown-backdrop
as a click area for closing dropdown menus when clicking outside the menu.
Via data attributes
Add data-toggle="dropdown"
to a link or button to toggle a dropdown.
<div class="dropdown">
<a data-toggle="dropdown" href="#">Dropdown trigger</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
...
</ul>
</div>
To keep URLs intact, use the data-target
attribute instead of href="#"
.
<div class="dropdown">
<a id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
Dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
...
</ul>
</div>
Via JavaScript
Call the dropdowns via JavaScript:
$('.dropdown-toggle').dropdown()
Options
None
Methods
$().dropdown(‘toggle’)
Toggles the dropdown menu of a given navbar or tabbed navigation.
Events
Event Type | Description |
---|---|
show.bs.dropdown | This event fires immediately when the show instance method is called. |
shown.bs.dropdown | This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete). |
hide.bs.dropdown | This event is fired immediately when the hide instance method has been called. |
hidden.bs.dropdown | This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete). |
$('#myDropdown').on('show.bs.dropdown', function () {
// do something…
})
ScrollSpy scrollspy.js
Example in navbar
The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well.

Usage
Via data attributes
To easily add scrollspy behavior to your topbar navigation, add data-spy="scroll"
to the element you want to spy on (most typically this would be the <body>
). Then add the data-target
attribute with the ID or class of the parent element of any Bootstrap .nav
component.
<body data-spy="scroll" data-target=".navbar-example">
...
<div class="navbar-example">
<ul class="nav nav-tabs">
...
</ul>
</div>
...
</body>
Via JavaScript
Call the scrollspy via JavaScript:
$('body').scrollspy({ target: '.navbar-example' })
Resolvable ID targets required
Navbar links must have resolvable id targets. For example, a <a href="#home">home</a>
must correspond to something in the DOM like <div id="home"></div>
.
Methods
.scrollspy(‘refresh’)
When using scrollspy in conjunction with adding or removing of elements from the DOM, you’ll need to call the refresh method like so:
$('[data-spy="scroll"]').each(function () {
var $spy = $(this).scrollspy('refresh')
})
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-
, as in data-offset=""
.
Name | type | default | description |
---|---|---|---|
offset | number | 10 | Pixels to offset from top when calculating position of scroll. |
Events
Event Type | Description |
---|---|
activate.bs.scrollspy | This event fires whenever a new item becomes activated by the scrollspy. |
$('#myScrollspy').on('activate.bs.scrollspy', function () {
// do something…
})
Togglable tabs tab.js
Example tabs
Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

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):
$('#myTab a').click(function (e) {
e.preventDefault()
$(this).tab('show')
})
You can activate individual tabs in several ways:
$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab a:first').tab('show') // Select first tab
$('#myTab a:last').tab('show') // Select last tab
$('#myTab 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.
<!-- Nav tabs -->
<ul class="nav nav-tabs">
<li><a href="#home" data-toggle="tab">Home</a></li>
<li><a href="#profile" data-toggle="tab">Profile</a></li>
<li><a href="#messages" data-toggle="tab">Messages</a></li>
<li><a href="#settings" data-toggle="tab">Settings</a></li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<div class="tab-pane active" id="home">...</div>
<div class="tab-pane" id="profile">...</div>
<div class="tab-pane" id="messages">...</div>
<div class="tab-pane" id="settings">...</div>
</div>
Fade effect
To make tabs fade in, add .fade
to each .tab-pane
. The first tab pane must also have .in
to properly fade in initial content.
<div class="tab-content">
<div class="tab-pane fade in active" id="home">...</div>
<div class="tab-pane fade" id="profile">...</div>
<div class="tab-pane fade" id="messages">...</div>
<div class="tab-pane fade" id="settings">...</div>
</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.
<ul class="nav nav-tabs" id="myTab">
<li class="active"><a href="#home" data-toggle="tab">Home</a></li>
<li><a href="#profile" data-toggle="tab">Profile</a></li>
<li><a href="#messages" data-toggle="tab">Messages</a></li>
<li><a href="#settings" data-toggle="tab">Settings</a></li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="home">...</div>
<div class="tab-pane" id="profile">...</div>
<div class="tab-pane" id="messages">...</div>
<div class="tab-pane" id="settings">...</div>
</div>
<script>
$(function () {
$('#myTab a:last').tab('show')
})
</script>
Events
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. |
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.target // activated tab

Tooltips tooltip.js
Examples
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.
Hover over the links below to see tooltips:

Four directions
Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
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).
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.
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 generated markup of a tooltip is rather simple, though it does require a position (by default, set to top
by the plugin).
1 <div class="tooltip">
2 <div class="tooltip-inner">
3 Tooltip!
4 </div>
5 <div class="tooltip-arrow"></div>
6 </div>
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 |
html | boolean | false | Insert HTML into the tooltip. If false, jQuery’s text method will be used to insert content into the DOM. Use text if you’re worried about XSS attacks. |
placement | string | function | ‘top’ | how to position the tooltip - top | bottom | left | right | auto. When “auto” is specified, it will dynamically reorient the tooltip. For example, if placement is “auto left”, the tooltip will display to the left when possible, otherwise it will display right. |
selector | string | false | If a selector is provided, tooltip objects will be delegated to the specified targets. |
title | string | function | ” | default title value if title attribute isn’t present |
trigger | string | ‘hover focus’ | how tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space. |
delay | number | object | 0 |
delay showing and hiding the tooltip (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: |
container | string | false | false |
Appends the tooltip to a specific element. Example: |
Data attributes for individual tooltips
Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.
Markup
<a href="#" data-toggle="tooltip" title="first tooltip">Hover over me</a>
Methods
$().tooltip(options)
Attaches a tooltip handler to an element collection.
.tooltip(‘show’)
Reveals an element’s tooltip.
$('#element').tooltip('show')
.tooltip(‘hide’)
Hides an element’s tooltip.

Popovers popover.js
Examples
Add small overlays of content, like those on the iPad, to any element for housing secondary information.
Plugin dependency
Popovers require the tooltip plugin to be included in your version of Bootstrap.
Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
Popovers in button groups and input groups require special setting
When using popovers 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 popover is triggered).
Popovers on disabled elements require wrapper elements
To add a popover to a disabled
or .disabled
element, put the element inside of a <div>
and apply the popover to that <div>
instead.
Static popover
Four options are available: top, right, bottom, and left aligned.
Popover top
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover right
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover bottom
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover left
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

and .in
class already applied to them.
.alert(‘close’)
Closes an alert.
$(".alert").alert('close')
Events
Bootstrap’s alert class exposes a few events for hooking into alert functionality.
Event Type | Description |
---|---|
close.bs.alert | This event fires immediately when the close instance method is called. |
closed.bs.alert | This event is fired when the alert has been closed (will wait for CSS transitions to complete). |
$('#my-alert').bind('closed.bs.alert', function () {
// do something…
})
Buttons button.js
Example uses
Do more with buttons. Control button states or create groups of buttons for more components like toolbars.
Stateful
Add data-loading-text="Loading..."
to use a loading state on a button.
<button type="button" data-loading-text="Loading..." class="btn btn-primary">
Loading state
</button>
Single toggle
Add data-toggle="button"
to activate toggling on a single button.
<button type="button" class="btn btn-primary" data-toggle="button">Single toggle</button>
Checkbox
Add data-toggle="buttons"
to a group of checkboxes for checkbox style toggling on btn-group.
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="checkbox"> Option 1
</label>
<label class="btn btn-primary">
<input type="checkbox"> Option 2
</label>
<label class="btn btn-primary">
<input type="checkbox"> Option 3
</label>
</div>
Radio
Add data-toggle="buttons"
to a group of radio inputs for radio style toggling on btn-group.
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="radio" name="options" id="option1"> Option 1
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2"> Option 2
</label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3"> Option 3
</label>
</div>
Usage
Enable buttons via JavaScript:
$('.btn').button()
Markup
Data attributes are integral to the button plugin. Check out the example code below for the various markup types.
Options
None
Methods
$().button(‘toggle’)
Toggles push state. Gives the button the appearance that it has been activated.
Auto toggling
You can enable auto toggling of a button by using the data-toggle
attribute.
<button type="button" class="btn" data-toggle="button">...</button>
$().button(‘loading’)
Sets button state to loading - disables button and swaps text to loading text. Loading text should be defined on the button element using the data attribute data-loading-text
.
<button type="button" class="btn" data-loading-text="loading stuff...">...</button>
Cross-browser compatibility
Firefox persists the disabled state across page loads. A workaround for this is to use autocomplete="off"
.
$().button(‘reset’)
Resets button state - swaps text to original text.
$().button(string)
Resets button state - swaps text to any data defined text state.
<button type="button" class="btn" data-complete-text="finished!" >...</button>
<script>
$('.btn').button('complete')
</script>
Collapse collapse.js
About
Get base styles and flexible support for collapsible components like accordions and navigation.
Plugin dependency
Collapse requires the transitions plugin to be included in your version of Bootstrap.
Example accordion
Using the collapse plugin, we built a simple accordion by extending the panel component.
<div class="panel-group" id="accordion">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
Collapsible Group Item #1
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse in">
<div class="panel-body">

</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">

</a>
</h4>
</div>
<div id="collapseTwo" class="panel-collapse collapse">
<div class="panel-body">

</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapseThree">
Collapsible Group Item #3
</a>
</h4>
</div>
<div id="collapseThree" class="panel-collapse collapse">
<div class="panel-body">

</div>
</div>
</div>
</div>
You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
simple collapsible
</button>
<div id="demo" class="collapse in">...</div>
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
.collapse
hides the content.collapse.in
shows the content.collapsing
is 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 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 selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the accordion-group 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
Examples
The slideshow below shows a generic plugin and component for cycling through elements like a carousel.
<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">
<div class="item active">
<img src="..." alt="...">
<div class="carousel-caption">
...
</div>
</div>
...
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
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.
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 active">
<img src="..." alt="...">
<div class="carousel-caption">
<h3>...</h3>
<p>...</p>
</div>
</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.
Usage
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.
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. |
Methods
.carousel(options)
Initializes the carousel with an optional options object
and starts cycling through items.
$('.carousel').carousel({
interval: 2000
})
.carousel(‘cycle’)
Cycles through the carousel items from left to right.
.carousel(‘pause’)
Stops the carousel from cycling through items.
.carousel(number)
Cycles the carousel to a particular frame (0 based, similar to an array).
.carousel(‘prev’)
Cycles to the previous item.
.carousel(‘next’)
Cycles to the next item.
Events
Bootstrap’s carousel class exposes two events for hooking into carousel functionality.
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…
})
Affix affix.js
Example
The subnavigation on the left is a live demo of the affix plugin.
Usage
Use the affix plugin via data attributes or manually with your own JavaScript. In both situations, you must provide CSS for the positioning of your content.
Positioning via CSS
The affix plugin toggles between three classes, each representing a particular state: .affix
, .affix-top
, and .affix-bottom
. You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions.
Here’s how the affix plugin works:
- To start, the plugin adds
.affix-top
to indicate the element is in it’s top-most position. At this point no CSS positioning is required. - Scrolling past the element you want affixed should trigger the actual affixing. This is where
.affix
replaces.affix-top
and setsposition: fixed;
(provided by Bootstrap’s code CSS). - If a bottom offset is defined, scrolling past that should replace
.affix
with.affix-bottom
. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, addposition: absolute;
when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the elemtn from there.
Follow the above steps to set your CSS for either of the usage options below.
Via data attributes
To easily add affix behavior to any element, just add data-spy="affix"
to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.
<div data-spy="affix" data-offset-top="60" data-offset-bottom="200">
...
</div>
Via JavaScript
Call the affix plugin via JavaScript:
$('#myAffix').affix({
offset: {
top: 100
, bottom: function () {
return (this.bottom = $('.bs-footer').outerHeight(true))
}
}
})
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-
, as in data-offset-top="200"
.
Name | type | default | description |
---|---|---|---|
offset | number | function | object | 10 | Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 } . Use a function when you need to dynamically calculate an offset. |
