Hello source code curious person from the INTERWEBS!
What you're doing is (in my opinion) the BEST way to learn and advance, that is, viewing the source. It's how I learnt, and how I'm still learning.
So go ahead, dig away and ask any questions. (see the contact page)
Techniques used on this site are all in the public domain, but the unique combination of CSS and images are what make this site's design.
Please don't steal wholesale, thats all I'm saying.
