what does div stand for
A div tag defines a division (or section) of a HTML document. DIV elements can be used to structure HTML documents as a hierarchy of divisions. So it would be fair to say that 'div' is short for 'division'. You have to go back to the specification for HTML 3.2 to find that out though, as it isn't stated at all in any newer specifications. Here is the link: http://www.w3.org/TR/REC-html32#div.
