Where I found a CSS Guide for edit in my theme? A basic codes, please..... :-\
Search for CSS to read up on how to change the css of your theme to your liking. There is no css guide as such.
If you use Firefox, the web developer toolbar extension will be your best friend. :)
There are many pages on the net dedicated to CSS. For a start, go to http://w3schools.com/css/default.asp
