Principles of Least Technology.
I have very strong opinions on certain things, especially in Web Design. Lately I've been forming the Principles of Least Technology - the idea that if you can accomplish the same effect using multiple technologies, you should use the oldest technology available. Why use a Flashy navigation when CSS and rollovers may be just as well? Even though browser compatibility and high resolution computers are less of problem than they used to be, there are still micro-devices to worry about - like PDAs, cellphones, and the Nintendo DS.
But I can't get my tables to behave quite properly when I'm using them to wrangle advanced graphic effects like you've seen here. Perhaps it's time to haul my ass out of 1999 and get more CSS on.
