Elements in the focus order need a role appropriate for interactive content
Log in (Premium content) Request a demo
User input elements must have appropriate roles, whether native HTML or a custom widget, to convey to screen reader users their meaning when landed on and given focus. If a custom widget, appropriate ARIA
role values must be used instead of abstract roles in order to correctly expose the purpose of the element.
The Algorithm, in Simple Terms
Checks all interactive elements in the focus order to ensure that the role value is valid and appropriate, whether native HTML or a custom ARIA widget.
Why this is Important
Elements in the focus order need a role appropriate for interactive content so that screen reader technology can communicate that information to users.
If interactive content elements do not have appropriate roles, the role will not be able to perform the accessibility function intended by the developer.
How to Fix the Problem
Ensure all elements in the focus order have an appropriate
role="", and if a custom widget, that they correspond to valid ARIA roles.
Ensure all device-independent user input methods have appropriate roles to enable interaction with form content.
