Work with pure CSS Don’t learn a new syntax as with preprocessors such LESS or SASS. You write css and you get css, and if you stop using stylecow or change to other css processor your code will remain valid.

Fix css automatically Vendor prefixes, old flexbox syntax, old webkit gradient, rem values, opacity, resolution media queries, pseudoselectors, etc. Don’t spend your time fixing, but creating.

Latest or future features Variables, nested rules, custom media, custom selectors, color manipulation, extend, calc, flexbox, etc. All using the w3c syntax. See all available plugins.

Advanced code generator There are two styles (normal and minify) but you can create your own code style. Do you prefer spaces or tabs, simple or double quotes, 0.5em or .5em ?

Easy to install No need to search and install dozens of packages and care about the correct order or the plugins (like POSTCSS). There’s no plugin conflicts, just install and use.

Easy to use Stylecow was built with simplicity in mind. It can be used both by html+css developers without javascript knowledge as by people requiring a more advanced tool.

Easy to integrate The stylecow.json file contains all your settings (browser support, plugins to use, code format, etc). You can run it by CLI, grunt, gulp, webpack or jsTransformer.

Easy to extend There’s a clean and robust API to work with the AST and create plugins easily in just minutes. Learn how
