What is the best way to learn how to layout your design images using CSS?

So I have finally caved and realized that 2009 means CSS no more table layouts or excessive HTML coding. It’s easy, but out of date. I have all my layout images sliced up and I want to use CSS to organize them to look like a layout again. Where is the best place for me to learn this. I am a pretty quick learner so I am not to worried about picking it up and have a little….very little experience with some CSS styles so hopefully that will at least be a start in learning this. Do you think i will struggle getting the hang of this?
