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

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.
<!-- 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">Home</a></li>
<li><a href="#profile">Profile</a></li>
<li><a href="#messages">Messages</a></li>
<li><a href="#settings">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
e.relatedTarget // previous 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:
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.

Four directions
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>
or <span>
, and apply the tooltip to that element instead.
Usage
Trigger the tooltip via JavaScript:
$('#example').tooltip(options)
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.

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>
or <span>
, and apply the popover to that element instead.
Static popover
Four options are available: top, right, bottom, and left aligned.

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">

</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
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">
<!-- 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.
Please visit http://shouldiuseacarousel.com/ for more details
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…
})
