I just switched from blogger to wordpress. I didn't know CSS a few days ago, but learned it in the past two days.
I had been using the Minima Theme on blogspot, and used that to create my own modified Minima theme. It's all located inside a single .htm file.
I tried modifying the original blogger files, but I didn't understand how it worked, so I built mine from the groundup.
Here's the file: http://www.webdroid.net/wp-content/themes/Webdroid/mockup.htm
It looks correct to me in Flock/IE6, IE7, FF 1.7, FF2b2. I think I'm good to go before I turn it into a theme, but I was hoping that maybe I could get some people to review the CSS and let me know their opinions - I'm sure there are bugs and recommended ways of doing things that I haven't done since I'm so new to CSS.
