Programming
A few sites for beginners
For CSS used by this site, visit the page about CSS.
To build a stylesheet without table and javascript, you can have a look at my introduction to tableless CSS (with most web browsers, with recent browsers).
For CSS you can find very good examples and explanations at The CSS Know-How Site, tutorial - look ma! no tables or A list apart.
And if you need a very good tool to test style sheets, try TopStyle Lite.
I'm still looking for very good links towards PHP scripting but you can find here why I decided to switch to PHP.
