The HTML <header></header> element was first introduced in HTML5 and Gecko 1.9.3. This element represents a group of introductory or navigational aids. It may contain some heading elements but also others elements like a logo, wrapped section's header, a search form, and so on. This element is not sectioning content and therefore doesn't induce a new section in the outline of the page.
