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.). - -{{< callout info >}} -{{< partial "callout-info-prefersreducedmotion.md" >}} -{{< /callout >}} - -Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards. - -## 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-bs-target` attribute (or `href` for links) that matches the `id` of the `.carousel` element. - -### Slides only - -Here's a carousel with slides only.

If multiple transitions are applied, make sure the transform transition is defined first (eg. `transition: transform 2s ease, opacity .5s ease-out`). - -## Sass - -### Variables - -{{< scss-docs name="carousel-variables" file="scss/_variables.scss" >}} - -## Usage - -### Via data attributes - -Use data attributes to easily control the position of the carousel. `data-bs-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-bs-slide-to` to pass a raw slide index to the carousel `data-bs-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`. - -The `data-bs-ride="carousel"` attribute is used to mark a carousel as animating starting at page load. If you don't use `data-bs-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: - -```js -var myCarousel = document.querySelector('#myCarousel') -var carousel = new bootstrap.Carousel(myCarousel) -``` - -### Options - -Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-bs-`, as in `data-bs-interval=""`. - -<table class="table"> - <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><code>interval</code></td> - <td>number</td> - <td><code>5000</code></td> - <td>The amount of time to delay between automatically cycling an item.
