CSS and browsers.

That's the good thing about CSS, if a browser doesn't understand a command then it will be ignored, although it can make the page look a bit boring.
If you are using position:fixed for a navigation bar then stick it along the top as  IE will just render it as an absolute and then not mess up the page. It will be position:fixed in Mozilla and Opera though.

You can try using two fixed sized

areas, one at the bottom for your logo's etc and use overflow:auto for the main

. This will provide an extra scroll bar giving the effect of a fixed area at the bottom..
This will work in IE and Mozilla but not in Opera,,aargh!
