I never used PostCSS, but from what I understand, not really. It seems to be a very arcane way of dealing with javascript. And you have to know about compilers to make any use of it. And I know a bit about compilers but so far I have no idea, how I could use it for my needs. But it seems to be some serious engeneering.
