It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators. - -In browsers where the [Page Visibility API](https://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.). - -{% include callout-info-prefersreducedmotion.md %} - -Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards. - -Lastly, if you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util). - -## Example - -Carousels don't automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they're not explicitly required. Add and customize as you see fit. - -**The `.active` class needs to be added to one of the slides** otherwise the carousel will not be visible. Also be sure to set a unique id on the `.carousel` for optional controls, especially if you're using multiple carousels on a single page. Control and indicator elements must have a `data-target` attribute (or `href` for links) that matches the id of the `.carousel` element. - -### Slides only - -Here's a carousel with slides only. Note the presence of the `.d-block` and `.w-100` on carousel images to prevent browser default image alignment. - -{% capture example %} -<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel"> - <div class="carousel-inner"> - <div class="carousel-item active"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" %} - </div> - </div> -</div> -{% endcapture %} -{% include example.html content=example %} - -### With controls - -Adding in the previous and next controls: - -{% capture example %} -<div id="carouselExampleControls" class="carousel slide" data-ride="carousel"> - <div class="carousel-inner"> - <div class="carousel-item active"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" %} - </div> - </div> - <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev"> - <span class="carousel-control-prev-icon" aria-hidden="true"></span> - <span class="sr-only">Previous</span> - </a> - <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next"> - <span class="carousel-control-next-icon" aria-hidden="true"></span> - <span class="sr-only">Next</span> - </a> -</div> -{% endcapture %} -{% include example.html content=example %} - -### With indicators - -You can also add the indicators to the carousel, alongside the controls, too. - -{% capture example %} -<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel"> - <ol class="carousel-indicators"> - <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li> - <li data-target="#carouselExampleIndicators" data-slide-to="1"></li> - <li data-target="#carouselExampleIndicators" data-slide-to="2"></li> - </ol> - <div class="carousel-inner"> - <div class="carousel-item active"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" %} - </div> - <div class="carousel-item"> - {% include icons/placeholder.svg width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" %} - </div> - </div> - <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev"> - <span class="carousel-control-prev-icon" aria-hidden="true"></span> - <span class="sr-only">Previous</span> - </a> - <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next"> - <span class="carousel-control-next-icon" aria-hidden="true"></span> - <span class="sr-only">Next</span> - </a> -</div> -{% endcapture %} -{% include example.html content=example %} - -### With captions - -Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`.

</a> -</div> -{% endcapture %} -{% include example.html content=example %} - - -## 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. If you don't use `data-ride="carousel"` to initialize your carousel, you have to initialize it yourself. **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 %} -var myCarousel = document.querySelector('#myCarousel') -var carousel = new bootstrap.Carousel(myCarousel) -{% endhighlight %} - -### Options - -Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`. - -<table class="table table-bordered table-striped"> - <thead> - <tr> - <th style="width: 100px;">Name</th> - <th style="width: 50px;">Type</th> - <th style="width: 50px;">Default</th> - <th>Description</th> - </tr> - </thead> - <tbody> - <tr> - <td>interval</td> - <td>number</td> - <td>5000</td> - <td>The amount of time to delay between automatically cycling an item.

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. -- `from`: The index of the current item -- `to`: The index of the next item - -All carousel events are fired at the carousel itself (i.e. at the `<div class="carousel">`). - -<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> - -{% highlight js %} -$('#myCarousel').on('slide.bs.carousel', function () { - // do something... -}) -{% endhighlight %} - -### Change transition duration - -The transition duration of `.carousel-item` can be changed with the `$carousel-transition` Sass variable before compiling or custom styles if you're using the compiled CSS. If multiple transitions are applied, make sure the transform transition is defined first (eg. `transition: transform 2s ease, opacity .5s ease-out`). |
