Goal
- Allow navigation using the keyboard or input devices or other mechanisms that are not reliant on the mouse.
Implementation
Be careful not to hide or remove the visual focus effect that indicates which element has been reached when navigating with the keyboard. In particular, do not override the default value of the CSS outline property without replacing it with another custom value or a visual effect which is sufficiently noticeable.
Do not remove keyboard focus using JavaScript (use of the onblurevent).
Control
This check is carried out on all interactive elements, primarily using the tabulation key and, in the interface of certain widgets, using specific movement keys (arrow keys).
For each interactive element contained in the pages checked:
- Check that there is at least a visual indication of the browser's default focus, or that there is a specific visual indication.
