Cool, thanks. Those are some pretty big numbers. What kind of a site is it?

It is really interesting to see the variance, btw. Twitter, KickStarter and Bootstrap running at thousands of rules, Google and Wikipedia at under 200. And a whole bunch in the 500-1000 range, such as Facebook, Amazon and Mozilla. I'm actually surprised at the relatively low rule-count for Facebook and Amazon as both those sites always gave me the impression (perhaps mistakenly) of having more CSS rules than I could read in a lifetime. Conversely, Github and Stack Overflow have more rules than I would have expected.

I guess that just goes to show that CSS complexity and visual clutter do not necessarily correlate.
