I think I am having a brain cramp.
I know that you are only supposed to use a "div id" once per page, and you can use "div class" multiple times (although, I think the page will still display fine, but validation will probably fail).
What is the reason for not just calling all of your divs "classes"? Always wondered. I know that you should normally use "div id" for your footers, headers, etc.
Guess I just don't totally understand why you cannot just call all of them "div classes". Could some please slap me in the head and explain this please? Thanks, Buffmin
