Nav (HTML element)
From Wiki @ Karl Jones dot com
In HTML5, the nav element represents side-wide navigation, or other major navigation links.
Semantic element
nav is a container for holding further content.
It has semantic meaning: "contents are navigation-related".
nav elements typically contain navigation bars, along with brand identification such as a logo, and so on.
HTML5 supports multiple nav elements per page. Use them sparingly, for major navigation. Avoid using nav elements for arbitary lists of links.
