sXwamp,I wouldn't worry about using CSS from another site for educational purposes. However, if you start to profit from it, you may have gone too far. As far as books, there are a few from O'Reily that you may check out at their website (google if need be). I always like to walk in a book store and look through a few books until I find a suitable one. This is really helpful when finding the right book for the right skill level.
P.S. I checked your site and saw your C++ with EMX ... glad my article on OS2ezine helped.
