A slideshow component for cycling through elements, like a carousel. Nested carousels are not supported.
The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
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.
The .active
class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
The .glyphicon .glyphicon-chevron-left
and .glyphicon .glyphicon-chevron-right
classes are not necessarily needed for the controls. Bootstrap provides .icon-prev
and .icon-next
as plain unicode alternatives.
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.
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.
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.
Call carousel manually with:
{% highlight js %} $('.carousel').carousel() {% endhighlight %}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 | null | "hover" | If set to "hover" , pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave . If set to null , hovering over the carousel won't pause it. |
wrap | boolean | true | Whether the carousel should cycle continuously or have hard stops. |
keyboard | boolean | true | Whether the carousel should react to keyboard events. |
.carousel(options)
Initializes the carousel with an optional options object
and starts cycling through items.
.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.
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. |
