CSSComb CSSComb

Build Status

CSSComb is a coding style formatter for CSS. You can easily write your own configuration to make your style sheets beautiful and consistent.

The main feature is the sorting properties in specific order. It was inspired by the same-named @miripiruni's PHP-based tool. This is the new JavaScript version, based on powerful CSS parser Gonzales.

Installation

npm install csscomb

To run csscomb, you can use the following command from the project root:

./node_modules/.bin/csscomb path[ path[...]]
./node_modules/.bin/csscomb --help

  Usage: csscomb [options] <file ...>

  Options:

    -h, --help           output usage information
    -V, --version        output the version number
    -c, --config [path]  configuration file path
    -l, --lint           in case some fixes needed returns an error
