I've decided to move on a bit and ditch tables in favour of using CSS (like the Hexus frontpage). Should I also look to use XTHML over HTML? The site I'm going to do won't be too demanding, but it will be nice to practice these things now if they are going to replace tables and HTML, and also which versions (XHTML 1.0/1.1, and which level of CSS 1/2).
Thanks
Also, any guides on CSS would be great, as well as the advantages they have over using tables etc.
