|
A slideshow component for cycling through elements—images or slides of text—like a carousel. In browsers where the [Page Visibility API](http://www.w3.org/TR/page-visibility/) is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.). **Nested carousels are not supported.**

<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
|
|

|
|
<span class="sr-only">Previous</span>
|
|
</a>
|
|
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
|
|
<span class="icon-next" aria-hidden="true"></span>
|
|
<span class="sr-only">Next</span>

</a>
|
|
</div>

#### Transition animations not supported in Internet Explorer 9
|
|
|
|
Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 9 doesn't support the necessary CSS properties. Thus, there are no slide transition animations when using that browser. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
|
|
{% endcallout %}
|
|
|
|
{% callout warning %}
|
|
#### Initial active element required
|
|
|
|
The `.active` class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
|
|
{% endcallout %}
|
|
|
|
### Optional captions
|
|
|
|
Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. Place just about any optional HTML within there and it will be automatically aligned and formatted.
|
|
|
|
<div class="bd-example">
|
|
<div id="carousel-example-captions" class="carousel slide" data-ride="carousel">
|
|
<ol class="carousel-indicators">
|
|
<li data-target="#carousel-example-captions" data-slide-to="0" class="active"></li>
|
|
<li data-target="#carousel-example-captions" data-slide-to="1"></li>
|
|
<li data-target="#carousel-example-captions" data-slide-to="2"></li>
|
|
</ol>
|
|
<div class="carousel-inner" role="listbox">

#### 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.
|

{% endcallout %}

|
## 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:
|
|
|
|
{% highlight js %}
|
|
$('.carousel').carousel()
|
|
{% endhighlight %}
|
|
|
|
### Options
|
|
|
|
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.
|
|
|
|
<div class="table-responsive">
|
|
<table class="table table-bordered table-striped">

|
|

|
|
<tbody>
|
|
<tr>
|
|
<td>interval</td>
|
|
<td>number</td>
|
|
<td>5000</td>
|
|
<td>The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.</td>
|
|

|
|

|
|

|
|

|
|
<td>"hover"</td>
|

|

|
|
<td>wrap</td>
|
|

|
|

|

|

|
|
<tr>
|
|

|
|

|
|

|

</tbody>
|

</table>
|
|
</div>
|
|
|
|
### Methods
|
|
|
|
#### `.carousel(options)`
|
|
|
|
Initializes the carousel with an optional options `object` and starts cycling through items.
|
|
|
|
{% highlight js %}
|
|
$('.carousel').carousel({
|
|
interval: 2000
|
|
})
|
|
{% endhighlight %}
|
|
|
|
#### `.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. 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">`).
|
|
|
|
<div class="table-responsive">
|
|
<table class="table table-bordered table-striped">
|

<thead>
|
|
<tr>
|
|
<th style="width: 150px;">Event Type</th>
|
|
<th>Description</th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr>
|
|
<td>slide.bs.carousel</td>
|
|
<td>This event fires immediately when the <code>slide</code> instance method is invoked.</td>
|
|
</tr>
|
|
<tr>
|
|
<td>slid.bs.carousel</td>
|
|
<td>This event is fired when the carousel has completed its slide transition.</td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
</div>
|
|
|
|
{% highlight js %}
|
|
$('#myCarousel').on('slide.bs.carousel', function () {
|
|
// do something…
|
|
})
|
