Remarks

The header element is only supported for webpages displayed in a Windows Store app using JavaScript. For more information, see Defining Document Compatibility.

A header element can contain the section's heading (an h1-h6 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.

The header element is not sectioning content; it does not introduce a new section.
