Interesante tutorial que muestra paso

a paso la construcción de layouts en CSS.

This guide will attempt to take you step by step, through the process of creating a fully functioning CSS layout. I will try my best to

explain the concepts behind each step, but a lot of the time other people have already covered these things better than I can. Because of this there will sometimes be links to more information on external

sites.
