Details

Rule ID Role 9
Definition Overriding a footer element's default role of contentinfo landmark must only be done in special cases.
Purpose
  • A top-level footer element has role restrictions as part of its definition in the W3C HTML5 Specification to help ensure the footer element semantics of identifying contentinfo landmark content.
  • A top-level footer element should only use role="presentation" if the content of the footer element is not being used to identify contentinfo landmark content (e.g. repairing poor page semantics).

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

Column Definitions

Element Identifier
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
Element Position
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
