<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.

I love beagles <em>so</em> much! Like, really, a lot. They’re adorable and
their ears are so, so snugly soft!

Usage notes
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 define 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.
Otherwise, when nested within said elements, it loses its landmark status and represents a group of introductory or navigational aids for the surrounding section. It 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.
When placed inside an <article>, <main>, <section>, <nav>, <aside>, or an element with the same ARIA role as these elements' implicit ARIA role, the <header> element has the generic role instead, and is no longer considered a landmark. In this case, it cannot be labeled with aria-label or aria-labelledby.
