Use case

WAI-ARIA landmark roles provide a powerful way to identify the organization and structure of a web page. By classifying and labelling sections of a page, they enable structural information that is conveyed visually through layout to be represented programmatically. Screen readers exploit landmark roles to provide keyboard navigation to important sections of a page. Landmark regions can also be used as targets for "skip links" and by browser extensions to enhanced keyboard navigation.

Proposal

Add the following landmark roles to the the available semantics roles in existing widget libraries:

• banner (when in context of the body element)
• complementary
• contentinfo (when in context of the body element)
• main
• navigation
• region (when it has an accessible name using aria-labelledby or aria-label)
• sectionhead
