HTML header element

The <header> HTML element represents introductory content, typically a group of introductory or navigational aids. It may contain some heading elements but also a logo, a search form, an author name, and other elements.

When not nested within sectioning content, <main>, or an element with the same ARIA role as these elements’ implicit ARIA role, then the <header> element has an identical meaning to the site-wide banner landmark role. It defines a global site header, which usually includes a logo, company name, search feature, and possibly the global navigation or a slogan. It is generally located at the top of the page.
