Success Criterion 2.4.11 - Level AA
Focus Not Obscured (Minimum)
When a user interface component receives keyboard focus, the component is not entirely hidden due to author-created content.
The intent of this Success Criterion is to ensure that the item receiving keyboard focus is always partially 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.
