Usage notes
The <header>
element is not sectioning content and therefore does not introduce a new section in the outline. That said, a <header>
element is intended to usually contain the surrounding section's heading (an h1
–h6
element), but this is not required.
Historical Usage
Although the <header>
element didn't make its way into specifications until HTML5, it actually existed at the very beginning of HTML. As seen in the very first website, it was originally used as the <head>
element. At some point, it was decided to use a different name. This allowed <header>
to be free to fill a different role later on.
Attributes
This element only includes the global attributes.
