An oldie but goodie. This was my first exposure to CSS and the foundation for the years I taught web design to low-income high schoolers. We would all go to an end-of-the-year web design competition at the local community college. The kids would have to explain CSS to the judges because they had no idea. :)

Many students walked away winning desktop computers (available due to computer lab upgrades). Probably the proudest accomplishments of my career.

If I remember right, I actually sent a few questions to Dave Shea, Eric Meyer, Andy Budd, etc and they replied with help. Forever grateful.
