Can anyone explain to me what this does?<p>I gather that it reorders the CSS statements somehow, but I'm not clear about exactly how it reorders them or why this is important.
Does this make a difference at all?<p>I've never heard arguments for CSS ordering as a performance issue.<p>It seems like removing CSS that doesn't do anything would be time better spent.
Another great tool: <a href="http://css-tricks.com/autoprefixer/" rel="nofollow">http://css-tricks.com/autoprefixer/</a><p>That is a postprocessor not preprocessor, meaning that it works on the actual file (just like CSS Comb)
