A lot of sites now are using CSS instead of tables to have a lighter markup. First you can find an interesting compilation of 3 columns CSS layout methods here.
On different projects, however I am not satisfied by the fact that most of the CSS layouts are ‘liquid’ which means the columns size increase or decrease with the browser size. What I am looking for is the strict equivalent of a classic Table design and I think I found something very neat.
It’s a page generator, totally free and it will save you a lot of time. The number of parameters is impressive but the result is amazing!
Problem solved :-)
