nah this site is fine, and its
HTML certified

I like
and sometimes centered does suit, and work really well. others well not sure, minute44 is wanting me to change rooflineuk.com but thats more hassle than its worth, next site i make i will center it and see how it goes
Bear in mind 2weeks ago id never used
CSS before, not to the extent of rooflineuk.com or for its real purpose.
