9.11 WCAG 2.1 Success Criterion 1.4.13 - Content on Hover or Focus

If additional content appears on focus/hover, you should ensure all of the following:

  • Dismissible: User can dismiss the additional content with the keyboard without moving focus/hover, e.g. via the escape key;
  • Hoverable: User can move the pointer over the additional content without making the additional content disappear; and
  • Persistent: The additional content remains visible until the hover or focus trigger is removed, or the user dismisses it, or its information is no longer valid.

Before Rectification

When user activates the “Support” menu via keyboard, a mega menu is displayed, which covered part of the main content. User is unable to view the content unless he/she moves the mouse pointer away from the mega menu.

After Rectification

A webpage sample with a mega menu disappeared.

Function is added for user to close the mega menu by pressing Escape key without moving the mouse pointer.
