Thank You!!! Rated 5 out of 5 stars
I've been looking for a tool to do this for a while now, and while it's not hard to find something that will reformat or clean your CSS for you, it's been difficult to find something that will audit your whole website and show a simple list of unused css selectors that can be removed....until now. Thank you very much for your work on this addon!
Now as I said there are already some "css cleaner" tools around, but it would be kind of nice if this addon were able to output new css files with the unused selectors removed and the remaining css cleaned up as much as possible. That's not a critical comment about something lacking though, just a suggestion ; )
BTW, I tried the url posted by Alex-1 about a tool he wrote to clean the styles out, but all I see on that site is a project that is totally unrelated to CSS. I'd just ignore the comment from Alex_1 as it is either outdated, or just off-topic spam.
