CSSLint

It parses a block of CSS code and points out basic problems.

The rules against which code is checked are customizable.

The developer can set his own, or remove the ones he does not intend to comply to.

CSSLint is also available as a Node.js package as well.

Needless to say, CSSLint was inspired by JSLint.
