- Principle: 2 Operable
What it is
Web content does not restrict use of input modalities available on a platform except where the restriction is essential, required to ensure the security of the content, or required to respect user settings.
How to test
- Check: Web content does not restrict use of input modalities available on a platform except where the restriction is essential, required to ensure the security of the content, or required to respect user settings.
- Use the sufficient techniques below as acceptable methods when applicable.
- Confirm none of the common failures apply.
Sufficient techniques (W3C)
- Only using high-level, input-agnostic event handlers, such as focus, blur, click, in Javascript (Potential future technique)
- Registering event handlers for keyboard/keyboard-like and pointer inputs simultaneously in Javascript; see Example 1 in Pointer Events Level 2 (Potential future technique)
Common failures (W3C)
- F98: Failure due to interactions being limited to touch-only on touchscreen devices
