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.
