Several new tags or elements have been added in HTML5. The header tag (<header>) is one of them. It is used as header of one or more sections or as a header of the document. HTML5 header tag should be used as a container of introductory contents like <h1> – <h6> tags, table of contents, search form, logo etc. with or without navigational links. More than header element can be used in a HTML5 document and it is generally placed at the beginning of the document or <article> tag.
Important points need to be remembered:
1. <header> and <head> tags are completely different.
2. A <header> tag can’t be placed within <footer> or <address> tag. Also header element can’t be placed within another header element.
3. HTML5 header element is supported by latest versions of all web browsers. Internet Explorer 8 or earlier versions of Internet Explorer do not support header element.
