		amitu on Dec 18, 2013 \| parent \| context \| favorite \| on: Show HN: Myth – CSS the way it was imagined That would be a noop with LESS/SASS unless the input CSS was not a "valid" CSS. This project will "enhance" "normal" CSS to take care of polyfill, which alone is a win. Take any CSS file you got, and it suddenly has all browser prefixes thanks to this tool. This is something LESS/SASS can not do.

Styl(us) can. My point is that calling it a 'post-processor' is a misnomer.
