## How it works

The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. 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 >}}

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. Note the presence of the `.d-block` and `.w-100` on carousel images to prevent browser default image alignment.

{{< example >}}
<div id="carouselExampleSlidesOnly" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder 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">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
</div>
{{< /example >}}

### With controls

Adding in the previous and next controls. We recommend using `<button>` elements, but you can also use `<a>` elements with `role="button"`.

{{< example >}}
<div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder 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">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleControls" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleControls" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

### With indicators

You can also add the indicators to the carousel, alongside the controls, too.

{{< example >}}
<div id="carouselExampleIndicators" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="1" aria-label="Slide 2"></button>
    <button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="2" aria-label="Slide 3"></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder 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">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

### With captions

Add captions to your slides easily with the `.carousel-caption` element within any `.carousel-item`. They can be easily hidden on smaller viewports, as shown below, with optional [display utilities]({{< docsref "/utilities/display" >}}). We hide them initially with `.d-none` and bring them back on medium-sized devices with `.d-md-block`.

{{< example >}}
<div id="carouselExampleCaptions" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button type="button" data-bs-target="#carouselExampleCaptions" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
    <button type="button" data-bs-target="#carouselExampleCaptions" data-bs-slide-to="1" aria-label="Slide 2"></button>
    <button type="button" data-bs-target="#carouselExampleCaptions" data-bs-slide-to="2" aria-label="Slide 3"></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#555" background="#777" text="First slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>First slide label</h5>
        <p>Some representative placeholder content for the first slide.</p>
      </div>
    </div>
    <div class="carousel-item">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#444" background="#666" text="Second slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>Second slide label</h5>
        <p>Some representative placeholder content for the second slide.</p>
      </div>
    </div>
    <div class="carousel-item">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>Third slide label</h5>
        <p>Some representative placeholder content for the third slide.</p>
      </div>
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleCaptions" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleCaptions" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

### Crossfade

Add `.carousel-fade` to your carousel to animate slides with a fade transition instead of a slide. Depending on your carousel content (e.g., text only slides), you may want to add `.bg-body` or some custom CSS to the `.carousel-item`s for proper crossfading.

{{< example >}}
<div id="carouselExampleFade" class="carousel slide carousel-fade" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder 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">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleFade" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleFade" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

### Individual `.carousel-item` interval

Add `data-bs-interval=""` to a `.carousel-item` to change the amount of time to delay between automatically cycling to the next item.

{{< example >}}
<div id="carouselExampleInterval" class="carousel slide" data-bs-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active" data-bs-interval="10000">
      {{< placeholder 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" data-bs-interval="2000">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleInterval" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleInterval" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

### Disable touch swiping

Carousels support swiping left/right on touchscreen devices to move between slides. This can be disabled using the `data-bs-touch` attribute. The example below also does not include the `data-bs-ride` attribute and has `data-bs-interval="false"` so it doesn't autoplay.

{{< example >}}
<div id="carouselExampleControlsNoTouching" class="carousel slide" data-bs-touch="false" data-bs-interval="false">
  <div class="carousel-inner">
    <div class="carousel-item active">
      {{< placeholder 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">
      {{< placeholder 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">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#333" background="#555" text="Third slide" >}}
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleControlsNoTouching" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleControlsNoTouching" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

## Dark variant

Add `.carousel-dark` to the `.carousel` for darker controls, indicators, and captions. Controls have been inverted from their default white fill with the `filter` CSS property. Captions and controls have additional Sass variables that customize the `color` and `background-color`.

{{< example >}}
<div id="carouselExampleDark" class="carousel carousel-dark slide" data-bs-ride="carousel">
  <div class="carousel-indicators">
    <button type="button" data-bs-target="#carouselExampleDark" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
    <button type="button" data-bs-target="#carouselExampleDark" data-bs-slide-to="1" aria-label="Slide 2"></button>
    <button type="button" data-bs-target="#carouselExampleDark" data-bs-slide-to="2" aria-label="Slide 3"></button>
  </div>
  <div class="carousel-inner">
    <div class="carousel-item active" data-bs-interval="10000">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#aaa" background="#f5f5f5" text="First slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>First slide label</h5>
        <p>Some representative placeholder content for the first slide.</p>
      </div>
    </div>
    <div class="carousel-item" data-bs-interval="2000">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#bbb" background="#eee" text="Second slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>Second slide label</h5>
        <p>Some representative placeholder content for the second slide.</p>
      </div>
    </div>
    <div class="carousel-item">
      {{< placeholder width="800" height="400" class="bd-placeholder-img-lg d-block w-100" color="#999" background="#e5e5e5" text="Third slide" >}}
      <div class="carousel-caption d-none d-md-block">
        <h5>Third slide label</h5>
        <p>Some representative placeholder content for the third slide.</p>
      </div>
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleDark" data-bs-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-bs-target="#carouselExampleDark" data-bs-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="visually-hidden">Next</span>
  </button>
</div>
{{< /example >}}

## Custom transition

The transition duration of `.carousel-item` can be changed with the `$carousel-transition-duration` 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`).

## 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=""`.

### Methods

{{< callout danger >}}
{{< partial "callout-danger-async-methods.md" >}}
{{< /callout >}}

You can create a carousel instance with the carousel constructor, for example, to initialize with additional options and start cycling through items:

```js
var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel, {
  interval: 2000,
  wrap: false
})
```

<table class="table">
  <thead>
    <tr>
      <th>Method</th>
      <th>Description</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><code>cycle</code></td>
      <td>Cycles through the carousel items from left to right.</td>
    </tr>
    <tr>
      <td><code>pause</code></td>
      <td>Stops the carousel from cycling through items.</td>
    </tr>
    <tr>
      <td><code>prev</code></td>
      <td>Cycles to the previous item. <strong>Returns to the caller before the previous item has been shown</strong> (e.g., before the <code>slid.bs.carousel</code> event occurs).</td>
    </tr>
    <tr>
      <td><code>next</code></td>
      <td>Cycles to the next item. <strong>Returns to the caller before the next item has been shown</strong> (e.g., before the <code>slid.bs.carousel</code> event occurs).</td>
    </tr>
    <tr>
      <td><code>nextWhenVisible</code></td>
      <td>Don't cycle carousel to next when the page isn't visible or the carousel or its parent isn't visible. <strong>Returns to the caller before the target item has been shown</strong>
    </tr>
    <tr>
      <td><code>to</code></td>
      <td>Cycles the carousel to a particular frame (0 based, similar to an array). <strong>Returns to the caller before the target item has been shown</strong> (e.g., before the <code>slid.bs.carousel</code> event occurs).</td>
    </tr>
    <tr>
      <td><code>dispose</code></td>
      <td>Destroys an element's carousel. (Removes stored data on the DOM element)</td>
    </tr>
    <tr>
      <td>
        <code>getInstance</code>
      </td>
      <td>
        Static method which allows you to get the carousel instance associated to a DOM element, you can use it like this: <code>bootstrap.Carousel.getInstance(element)</code>
      </td>
    </tr>
    <tr>
      <td>
        <code>getOrCreateInstance</code>
      </td>
      <td>
        Static method which returns a carousel instance associated to a DOM element or create a new one in case it wasn't initialized.
        You can use it like this: <code>bootstrap.Carousel.getOrCreateInstance(element)</code>
      </td>
    </tr>
  </tbody>
</table>

### 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.
- `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">
  <thead>
    <tr>
      <th style="width: 150px;">Event type</th>
      <th>Description</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><code>slide.bs.carousel</code></td>
      <td>Fires immediately when the <code>slide</code> instance method is invoked.</td>
    </tr>
    <tr>
      <td><code>slid.bs.carousel</code></td>
      <td>Fired when the carousel has completed its slide transition.</td>
    </tr>
  </tbody>
</table>

```js
var myCarousel = document.getElementById('myCarousel')

myCarousel.addEventListener('slide.bs.carousel', function () {
  // do something...
})
```
