Oh yeah, and here's a great cheat method. Cheats are the best shortcut, who wants to do it the right way, huh.
Find a site with some neat stuff you like - then check out their CSS file. Easy: look at the code source and get their CSS file - if it is /main.css then browse to:
www[DOT]neatsite.com/main.css
...and check it out. Then you'll get all the neat tricks like:
display:none;
text-align:justify;
...that maybe they don't tell you in the tutes.
