I built this because the only existing solutions to finding old legacy CSS that aren't being used anymore that I could find are Firefox plugins. Dust Me Selectors and CSS Usage being the two big ones. I found that I am often at a machine without Firefox, or I don't want to install an addon (or addon for an addon in the case of CSS Usage) just to quickly find out what CSS selectors aren't being used on a given page. All feedback is very welcome!
