<header>: The Header element

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

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.

Usage notes

The <header> element has an identical meaning to the site-wide banner landmark role, unless nested within sectioning content. Then, the <header> element is not a landmark.

The <header> element can define a global site header, described as a banner in the accessibility tree. It 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.

Otherwise, it is a section in the accessibility tree, and usually contains the surrounding section's heading (an h1 – h6 element) and optional subheading, but this is not required.

Historical Usage

The <header> element originally existed at the very beginning of HTML for headings. It is seen in the very first website. At some point, headings became <h1> through <h6>, allowing <header> to be free to fill a different role.

Attributes

This element only includes the global attributes.

Accessibility

The <header> element defines a banner landmark when its context is the <body> element. The HTML header element is not considered a banner landmark when it is descendant of an <article>, <aside>, <main>, <nav>, or <section> element.
