Techniques
  • The header element defines a banner landmark, except when it is a descendant of any of the following elements: article, aside, main, nav or section.
  • If the header element technique is not being used, a role="banner" attribute on the container element for the branding content can be used to define a banner landmark.
  • In websites that support mashups using iframe or frame elements, a banner landmark is allowed in each frame.
  • If the page is part of a website supporting mashups, use the aria-labelledby or aria-label attribute to differentiate banner landmarks in each frame.
Manual Checks
  • Banners are a convention used on most web sites to convey branding information, and may also be used as a location for advertising information.
  • The banner landmark identifies the banner content on the page.

"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.
