name: "Tabs (experimental)"
description: "The tabs component lets users toggle between related sections of content."
body: |
  This component is based on the [design system tabs component](https://design-system.service.gov.uk/components/tabs/)
  and is currently experimental. If using this component, please feed back any research findings to the
  design team.

  The tabs component lets users navigate between related sections of content on a single page,
  displaying one section at a time. Note that they are not intended to be used to navigate
  between different pages.

  The content block MUST be passed as a block to avoid the risk of unsanitised HTML.

  - Tabs must:
    * accept focus
    * be usable with a keyboard
    * indicate when they have focus
    * be usable with touch
    * be usable with voice commands
    * have visible text
