A carousel, or slider, provides a way to have a gallery or series of slides of content that are automatically advanced.

The carousel plugin provides the styles and interactivity. To use this plugin, you'll need to follow these markup instructions:

  1. Create a generic wrapper element <div> that will house the carousel and give it a class of flexslider.
  2. Add a list element <ul> and give it a class of slides.
  3. Add list item elements <li> for each slide of content you'd like to have displayed.
    Any content can be put into the list item as a slide. The most common use is to include an image element <img>. Each slide should be the same size to avoid awkward styling.
  4. Load the carousel plugin with <script>WDN.initializePlugin('carousel');</script>
    Please note, you only need to run this script once per page. Putting it at the bottom of your content ensures that the carousel loads when ready.

Accessibility Considerations: 

  • All content included in the slides should contain all necessary accessibility markup, like alt attributes on images.
  • While the plugin provides some general help for accessible users to limit the advancing of slides while interacting or focusing on a slide of content, the transitions may cause issue for people with visual impairments.
  • You should avoid hiding the navigational, paging elements of the carousel as these provide useful targets for accessible users to quickly advance content. Keyboard shortcuts are enabled by default.

Usability Considerations: 

  • The use of carousels for anything other than photo galleries is generally discouraged. Research has shown that visitors often ignore this moving, changing content. Try to focus on a single piece of content or call-to-action in order to maximize the impact.
  • Hiding page content behind an interaction can frustrate visitors that a looking for a specific piece of content.
