Carousel

How it works

The animation effect of this component is dependent on the prefers-reduced-motion media query. See the reduced motion section of our accessibility documentation.

Example

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

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

With controls

With indicators

With captions

Crossfade

Add .carousel-fade to your carousel to animate slides with a fade transition instead of a slide.

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

Dark variant

Add .carousel-dark to the .carousel for darker controls, indicators, and captions.

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:

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="".

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.
keyboard boolean true Whether the carousel should react to keyboard events.
pause string | boolean "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 false, hovering over the carousel won't pause it.

On touch-enabled devices, when set to "hover", cycling will pause on touchend (once the user finished interacting with the carousel) for two intervals, before automatically resuming. Note that this is in addition to the above mouse behavior.
slide string | boolean false Autoplays the carousel after the user manually cycles the first item. If "carousel", autoplays the carousel on load.
wrap boolean true Whether the carousel should cycle continuously or have hard stops.
touch boolean true Whether the carousel should support left/right swipe interactions on touchscreen devices.

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

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

Method Description
cycle Cycles through the carousel items from left to right.
pause Stops the carousel from cycling through items.
prev Cycles to the previous item. Returns to the caller before the previous item has been shown (e.g., before the slid.bs.carousel event occurs).
next Cycles to the next item. Returns to the caller before the next item has been shown (e.g., before the slid.bs.carousel event occurs).
nextWhenVisible Don't cycle carousel to next when the page isn't visible or the carousel or its parent isn't visible. Returns to the caller before the target item has been shown
to Cycles the carousel to a particular frame (0 based, similar to an array). Returns to the caller before the target item has been shown (e.g., before the slid.bs.carousel event occurs).
dispose Destroys an element's carousel. (Removes stored data on the DOM element)
getInstance Static method which allows you to get the carousel instance associated with a DOM element.

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">).

Event type Description
slide.bs.carousel Fires immediately when the slide instance method is invoked.
slid.bs.carousel Fired when the carousel has completed its slide transition.

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).
