Accessibility: Best Practice – Page Must Not Have More Than One Banner Landmark

The role=”banner” ARIA landmark should only appear once on an element that is unique to the HTML document.

HMTL5 specification allows multiple instances of an equivalent header landmark value, however it is appropriate in most web designs to have only one banner landmark whether it is specified using ARIA or HTML5.
