Details

Rule ID Role 10
Definition Overriding heading element's (h1-h6) default role of heading must only be done in special cases.
Purpose
  • Heading elements (h1-h6) have role restrictions as part of its definition in the W3C HTML5 Specification to help ensure the heading element semantics of identifying heading and tab content.
  • Heading elements (h1-h6) should only use role="presentation" if the content of the heading element is not being used to identify heading and tab content (e.g. repairing poor page semantics).

Techniques
  • Heading elements (h1-h6) typically do not need any role definition, there default role is heading.
  • Heading elements (h1-h6) used as the tabs in a tabpanel widget need to have the role="tab".
  • In rare cases role="presentation" can be used when a heading element does not provide a label for a section of content or is a tab in a tabpanel widget. Although a better solution is to change the element to something more semantically meaningful.

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.
