New tag

HTML5 provides new elements and attributes such as <nav> (site navigation block) and <footer>. This tag will facilitate indexing of search engines and better help with small-screen devices and visually impaired people, and provide new features such as <audio> and <video> tags for other browsing elements.

Some obsolete HTML4 tags will be canceled. These include tags that are purely display effects, such as <font> and <center>, which have been replaced by CSS.
