Converting to CSS...

Hi,

Have just done an exhaustive search across the net and came across this
newsgroup. Am needing help to create a fixed height header row, a fixed
height footer row and a fluid center row. I have created a table structure
to demonstrate what I want to do at this URL:

There seems to be lots of pages on 3 cols css, but nothing on the effect
that I want to acheive... and as I'm fairly new to CSS, I am not sure where
to go. The reason for the change from tables to CSS is for web standards
compliance.

Any help would be greatly apprecaited. Many thanks

Thom.
