The <header> element is one of HTML5's semantic elements. Whereas non-semantic elements such as a <div> can be used for web page layout, it provides no information about the meaning of its content. The semantic elements allow search engine spiders to more accurately index a webpage, and allow to accessibility applications such as document readers to present a document.
