Very non-lottery-related; web programmers may be interested:

I finally found a terrific book about Cascading Style Sheets.  I have been looking for a good reference guide, which doesn't assume I'm a beginner, and that specifies every single element available in a straightforward way.  Like a dictionary for CSS.

It's a really nice size to sit on your desk as you program.

I'm going to be spending time this year updating Lottery Post to become closer to a strict HTML 4 standard, so use of quality CSS code is a must.
