April 5th, 2006 is the first annual CSS Naked Day. If you are viewing this on April 5th then you will see no styling. Any other day it will look normal. A properly written web page should fail gracefully and still be useable by browsers that do not understand CSS. It is the web standards way. 🙂
Welcome to the first annual CSS naked day which will be happening April 5th, 2006. The idea behind this event is to promote Web Standards. Plain and simple. This includes proper use of (x)html, semantic markup, a good hierarchy structure, and; well, a fun play on words. I mean, who doesn’t want to get naked?. Feel free to see the original reference article for more information.
