How does Elegantizr work?
The source is really small ( http://code.google.com/p/elegantizr/source/browse/trunk/elegantizr.css ) and I can't figure out how it works.
As far as how it works, there is a CSS property called "content" (more on it here: https://developer.mozilla.org/en/CSS/content).
This utilizes the :before pseudo-selector on any given HTML page and outputs "April Fool ô¿ô" several times above the page (since it is a :before).
Then as I read I realized it was April Fools joke. Peace!
