    Getting Started

    This plugin was developed against

    If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

    npm install grunt-contrib-csslint --save-dev
    npm install grunt-csslint-plus --save-dev

    Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


    N.B. since grunt-csslint-plus is an extension of grunt-contrib-css, both packages must be installed for it to work!


    To include your own custom rules for csslinting, you must provide an array of directories containing rules in the following way:

    csslint_plus: {
      rules: [

    Two example rules are provided in the node module

    Csslint Setup

    Since this package is an extension of Grunt CSSLint, this package needs to be set up as well. You can find installation instructions here.

    Or, add the following to your gruntfile.js

    csslint: {
        strict: {
            options: {
                import: 2
            src: ['.../**/*.css']

    Csslint Plus Task

    Run this task with grunt csslint_plus command

    Custom Rule Files

    To define your own custom css rules, you must provide rules in the following example format:

    var rule = {
      id: "example_id",
      name: "example_rule_name",
      desc: "description of rule",
      init: function(parser, reporter) {
        var rule = this;
        parser.addListener("startRule", function(evt) { ... } ), # example listeners
        parser.addListener("endRule", function(evt) { ... } ) # another example listener
    exports.Rule = rule

    Probably the best way to get documentation is to look through the rules available in csslint as there are a lot more listeners.


    npm i grunt-csslint-plus
