CSS design

two CSS sample webpages. Simple  
Hope you like them.

oh~!IT'S COOL!!! I LIKE IT---VERY MUCH.
AND CAN YOU DO SOME EXPLAIN OF CSS PAGES?

They are not cool, actually. Just simple. But it's good that you like them. I still need to do more research on CSS before I can explain the structure pf the HTML files and CSS files thoroughly.
If you like, you could have a look at www.csszengarden.com. Very good site to study CSS.
