CSSO [1] is a tool that removes duplicate declarations during minification instead of just warning about them. It also performs more advanced structural optimizations.

I think the purpose of this package is more about making existing source code easier to maintain (applying DRY principals to CSS) than about browser-oriented optimization (thus purpose of CSSO.)

You could keep the csscss'ed source in version control (easy to maintain), and use csso as an automated step before deploying.

css-ratiocinator [1] is also another tool someone mentioned to me after I launched cssscss.

And rework [1] allows you to change url()'s, inline images, change vendor prefixes and more...

Is there something that can do all of this and remove the unused css after clicking through the site with a browser?
