After reading benefits of CSSLint there is no doubt in my mind that we should use it. Here [1] are some of the benefits. They range from possible errors to compatibility to performance, etc. With grunt we can use grunt-lesslint [2], which employs CSSLint under the hood so we can also tweak it using CSSLint rules.
What do you guys think?
