Thought css lib would validate CSS but I was wrong =(
No luck with csslint either -_-
No luck with ycssmin either...
Turns out RECESS works but is built on top of LESS.Parser
However, it fails to fail on poor CSS properties
Going to open up an issue against this but dropping CSS validation for now
Repaired stylus but seems to be running into a double callback?
Back on the road of development
