Success Criterion 2.4.12 - Level AAA

Focus Not Obscured (Enhanced)

When a user interface component receives keyboard focus, no part of the component is hidden by author-created content.

The intent of this Success Criterion is to ensure that the item receiving keyboard focus is always visible in the user's viewport. For sighted people who rely on a keyboard (or on a device that operates through the keyboard interface, such as a switch or voice input), knowing the current point of focus is critical. The component with focus signals the interaction point on the page. Where users cannot see the item with focus, they may not know how to proceed, or may even think the system has become unresponsive.
