The <head> Tag in HTML 5
The <head> tag creates the head section of the document, which contains the HTML page title that appears in the title bar of the web browser window plus other metadata information describing the document and possibly linking to other related resources. The head element is the first of the two elements making up the inner HTML of the top html element, preceding the <body> start tag for the body section, which is created by the body element in the top html element inner HTML. The <head> tag is one of the structure tags in HTML.
