Banner role is assigned to the portion of the page which contains the website specific content rather than a page specific content. Usually the portion of the page that includes logo, navigation panel and the search functionality together are marked with role=â€bannerâ€. Take care that no more than one element is marked as role=â€bannerâ€ in the webpage.
<div role=”banner”>Header , navigation and search sections form a banner region </div>
