There’s not much details about it. This is merely to see if you’re up to the challenge to put your website on the line. If you run an e-commerce website, you ought not participate; this is purely for those with personal blogs or for those who run publications or…whatever. All the more props to you if you run a large website!
The fact of the matter is, if you’re writing good solid markup to begin with, it shouldn’t be all that bad anyway. It will be a test case to see how usable your website is to others without a design.
So in the meantime, don’t hesitate to prepare your site for the big day. If you feel the need to explain why your site is naked
(without design) to your visitors, simply put the following markup at the top fo your page (remember that this is totally optional):
"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 of course, a good ‘ol play on words. It’s time to show off your <body>."
Then on April 9th, simply remove all CSS from your website, stripping it entirely of its design.
