It is a bit dishonest to call it "css" when most of the heavy lifting (the math) is done by javascript.

Agreed, the CSS is basically just importing the Latin Modern font and doing some spacing and font-size specifications. Not wanting to be mean, but there's nothing special about it. The credit should go to MathJax [1] which is rendering the math.
