grunt-contrib-csslint

Lint CSS files

grunt-contrib-csslint v0.4.0

Lint CSS files

This plugin requires Grunt >=0.4.0

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

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

grunt.loadNpmTasks('grunt-contrib-csslint');

Run this task with the grunt csslint command.

Any specified option will be passed through directly to csslint, thus you can specify any option that csslint supports. The csslint API is a bit awkward: For each rule, a value of false ignores the rule, a value of 2 will set it to become an error. Otherwise all rules are considered warnings.

For the current csslint version, these rules are available:

  • important
  • adjoining-classes
  • known-properties
  • box-sizing
  • box-model
  • overqualified-elements
  • display-property-grouping
  • bulletproof-font-face
  • compatible-vendor-prefixes
  • regex-selectors
  • errors
  • duplicate-background-images
  • duplicate-properties
  • empty-rules
  • selector-max-approaching
  • gradients
  • fallback-colors
  • font-sizes
  • font-faces
  • floats
  • star-property-hack
  • outline-none
  • import
  • ids
  • underscore-property-hack
  • rules-count
  • qualified-headings
  • selector-max
  • shorthand
  • text-indent
  • unique-headings
  • universal-selector
  • unqualified-attributes
  • vendor-prefix
  • zero-units

For an explanation of those rules, check the csslint wiki.

Side note: To update this list, run this:

node -e "require('csslint').CSSLint.getRules().forEach(function(x) { console.log(x.id) })"

A few additional options are supported:

Type: string
Default: null

If this filename is specified, options and globals defined therein will be used. Task and target options override the options within the .csslintrc file. It should be a JSON file, but it supports comments:

{
  // unicorns
  "qualified-headings": true,
  "unique-headings": true,
  "known-properties": false
}

Type: array
Default: null

If the formatters options is specified, the grunt csslint task is able to use the all formatters provided by csslint.

For the current csslint version, the following formatters are supported:

  • text
  • compact
  • lint-xml
  • csslint-xml
  • checkstyle-xml
  • junit-xml

For an explanation of those formatters, check the csslint wiki, section Options/--format.

Type: boolean
Default: false

If the absoluteFilePathsForFormatters option is specified and set to true, the file names in the generated reports are absolute.

csslint: {
  strict: {
    options: {
      import: 2
    },
