Carousel

The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators. Please be aware that nested carousels are not supported.

Sizing

Carousels don’t automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. When using images in each slide, ensure they all have the same dimensions (or aspect ratio).

When using img-src or img-blank on <b-carousel-slide>, you can set the image width and height via the img-width and img-height props on <b-carousel> and have these values automatically applied to each carousel-slide image.

Note that images will still be responsive and automatically grow or shrink to fit within the width of its parent container.

Internally, <b-carousel-slide> uses the <b-img> component to render the images. The img-* props map to the corresponsing props available to <b-img>.

Interval

Carousel defaults to an interval of 5000ms (5 seconds). To pause the carousel from auto sliding, set the interval prop to 0. To restart a paused carousel, set the interval back to the number of ms.

In browsers where the Page Visibility API 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.).

Controls and Indicators

Set the prop controls to enable the previous and next control buttons.

Set the prop indicators to show the slide indicator buttons.

Both indicators and controls can be set at the same time or independently.

V-model support

Programmaticaly control which slide is showing via v-model (which binds to the value prop). Note, that slides are indexed starting at 0.

Accessibility

Carousels are generally not fully compliant with accessibility standards, although we try to make them as accessible as possible.

By providing a document unique value via the id prop, <b-carousel> will enable accessibility features. It is highly recommended to always add an ID to all components.

All carousel controls and indicators have aria labels. These can be customized by setting the various label-* props.
