While I agree that exceptions in very rare cases are needed, exceptions are becoming the norm and, like I said, are coupling functionality and content. This is why CSS was created, to decouple style from content, and now? We are are throwing all that work away because an entire generation of web devs are just too lazy to look it up.

By the way, a quick search for sticky page footer on Google turned up this as the first result -- no JS needed, and it didn't even look that hard (http://www.cssstickyfooter.com/using-sticky-footer-code.html).
