Content on Hover or Focus

Rule ID Keyboard 7
Conformance Required
Definition When pointer hover or keyboard focus triggers additional content to become visible and then hidden, the content is dismissible, hoverable and persistent, there are some exceptions.
Purpose
  • Users with low vision who view content under magnification will be better able to view content on hover or focus without reducing their desired magnification.
  • Users who increase the size of mouse cursors via platform settings or assistive technology will be able to employ a technique to view obscured content on hover.
  • Users with low vision or cognitive disabilities will have adequate time to perceive additional content appearing on hover or focus and to view the trigger content with less distraction.
  • Users with low pointer accuracy will be able to more easily dismiss unintentionally-triggered additional content.
