Extracts CSS classes from a selection of markup and formats it into a useable list to paste into your CSS/LESS/SASS/whatever. Uses htmlparser2 so should be reasonably good at finding the right stuff.
Uses the ncp package, may require external dependencies in Linux and macOS.
Many minor fixes. Tags with no attributes, empty classes and things other than tags (script blocks, comments etc...) will now be properly ignored
Special thanks to ardcore for this Atom plugin from which this extension draws its origins.
