A Bit of CSS

I'm doing some experimenting with CSS, after many years of goofing off after a good start at web design in 1995 (yeah I know) it's time for a come-back!
I'm not sure what I can or cannot do here on Blogger, but I,m going to try some stuff since I don't have a webpage Blogger will do. Afterall it is really a ready made webpage that you personalize.
Let the fun begin.
