Where receiving pointer hover or keyboard focus triggers user interface components to be visible, information needed to identify that user interface components are available is visible, except when:
|Techniques:||Techniques are not yet available for WCAG 2.2 success criteria.|
The purpose of this success criterion is to ensure that users can easily locate controls.
How to Meet
The use of hidden controls is not common in digital publications because these works are typically read on devices without hover or keyboard interfaces. Controls are typically persistent so that they can work with touch devices.
If authors do create interfaces with hidden controls, however, they need to ensure that users can access persistent versions. This could be by allowing the user to make the hidden controls persistent (e.g., through a toggle) or by providing a persistent version of the control at some stage of interaction (e.g., making the controls persistent once the interface is activated).
The knowledge base does not currently include information on control visibility due to the lack of implementation in publishing formats. Refer to the WCAG guidance documents for additional information.
