Content Collection

Level

The content on hover is the content that appears and disappears in coordination with keyboard focus or mouse pointer. This activity can sometimes cause accessibility issues, such as:

  • the user may not have intended to trigger the interaction
  • the user may not know new content has appeared
  • the new content may interfere with a user’s ability to do a task

Using the content on hover can be accessible if it is dismissible, hoverable or persitant

Dismissible

A mechanism is available to dismiss the additional content without moving pointer hover or keyboard focus unless the additional content communicates an input error or does not obscure or replace other content.

Hoverable

If pointer hover can trigger the additional content, then the pointer can be moved over the additional content without the additional content disappearing.

Persistent

The additional content remains visible until the hover or focus trigger is removed, the user dismisses it, or its information is no longer valid.
