Definition |
Overriding a nav element's default role of navigation landmark must only be done in special cases. |
Purpose |
- A
nav element has role restrictions as part of its definition in the W3C HTML5 Specification to help ensure the nav element semantics of identifying navigation landmark content.
- A
nav element should only use role="presentation" if the content of the nav element is not being used to identify navigation landmark content (e.g. repairing poor page semantics).

Techniques |
- The
nav element with no role value by default defines a navigation landmark, but the role="navigation" is allowed to support legacy pages.
- If the
nav element does not identify a navigation landmark content use a different element that does identify the semantics of content.
- In rare cases
role="presentation" can be used when the nav element does not represent the website or page navigation links on the page (e.g. repairing poor page semantics).
- Any other
role values are not allowed on nav elements.
