The header element represents a group of introductory or navigational aids.

A header element is intended to usually contain the section's heading (an h1h6 element or an hgroup element), but this is not required. The header element can also be used to wrap a section's table of contents, a search form, or any relevant logos.

Here are some sample headers. This first one is for a game:

 <p>Welcome to...</p>

The following snippet shows how the element can be used to mark up a specification's header:

The header element is not sectioning content; it doesn't introduce a new section.

In this example, the page has a page heading given by the h1 element, and two subsections whose headings are given by h2 elements. The content after the header element is still part of the last subsection started in the header element, because the header element doesn't take part in the outline algorithm.
