I don't think this is a parody site. The same author created the Hartija print css framework and a few other css frameworks. There is also good documentation and demo code available for the Golden CSS framework. It looks very interesting.

http://www.vcarrer.com/2009/02/golden-grid.html (linked from the "article") does make it sound like a spoof. e.g.:

"Dimensions

One, Two, Three - jump. Where is four? We usually stop at tree. Why? Three is the magic number. Three is a lucky number. Three is the fourth of Fibonacci. It is the first number that breaks the symmetry of 2.

I decided to build the golden grid based on this number.

3 + 3 and 3 + 3 + 3 +3 => 6/12 grid system"

Now I know how programmers must have felt when Why The Lucky Stiff came on the scene.
