I am new to the whole HTML5 and CSS3 advancement. And have question in respect to nesting one within an other.
I am working on a WordPress theme, and would like to place a Menu within the Header. Under the old ways of HTML and CSS I would just use a div id=”nav”, and nest this within the div id=header. But I don’t know if I could nest a NAV Tag within a HEADER Tag. Would this be proper Mark-Up? Or in this case, just use a div id=”nav”
