| 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.
