Rule ID Heading 7
Definition If a contentinfo, complementary, form, navigation or search landmark contains a heading element, the first heading should be an h2 element.
Purpose
  • Headings provide a redundant way for people to navigate and orient themselves to content on a web page.
  • The use of an h2 element as the first heading in a landmark (except the main and banner landmarks) supports a consistent use of headings for finding the main sections in a web page.

  • h2
Techniques
  • Locate an h2 element at the beginning of the content in the landmark to describe the content in the landmark.
  • The h2 element can be used as the accessible name for a landmark using the aria-labelledby attribute on the landmark to point to an id attribute on the h2 element.
  • The h2 element can be hidden from the graphical rendering using offscreen CSS positioning (e.g. position: absolute )techniques.

"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).

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.
