Mincss clears the junk out of your CSS finds and removes selectors you’re not using
In the past we�ve covered ways Web designers can keep their CSS clean, highlighting ProCSSor, a desktop app for the Mac which cleans up and compresses your code; as well as CSS Compressor; Code Beautifier; and CSS Beautify.
None of these options, however, remove unused CSS to help keep your site extra lean. That�s where mincss comes in.
As its creator Peter Bengtsson explains, mincss is a tool that when given a URL (or multiple URLs) downloads that page and all its CSS and compares each and every selector in the CSS� to find out what isn�t used. The result is your original CSS file with those unused selectors (not found in your HTML) removed.
Put more simply, if I style a paragraph of text, and then end up replacing that paragraph with a video, I would be left with unused paragraph styles in my CSS. Mincss makes sure you�ve removed these unused styles to keep your CSS light and clean.
Bengtsson notes that mincss is also particularly handy when using a heavy, uncustomized framework like Bootstrap. This tool, however, doesn�t play friendly with elements created by JavaScript.
