Stylecow: full featured node package to parse and manipulate your CSS code (oscarotero.github.io)

The main purpose of Stylecow is to bring more CSS support to all browsers. You write CSS and you get CSS. You don't have to learn another different language such LESS, SASS, etc. Stylecow converts your code to be more compatible with all browsers throught plugins without writing any non-standard code. So you can use Stylecow just to fix your modern CSS code and make it compatible with old browsers. And if you stop using Stylecow, your CSS code will remain CSS code.
