Mutate CSS selectors.

grunt-css-selectors

Mutate CSS selectors.

This plugin requires Grunt ~0.4.1

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-css-selectors --save-dev

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

grunt.loadNpmTasks('grunt-css-selectors');

In your project's Gruntfile, add a section named css_selectors to the data object passed into grunt.initConfig().

grunt.initConfig({
  css_selectors: {
    options: {
      // Task-specific options go here. 
    },
    your_target: {
      // Target-specific file lists and/or options go here. 
    },
  },
})

Type: String Default value: ' ' (four spaces)

Intendation to apply to rules when Rework-ing the CSS.

Type: Object[] Default value: []

A collection of mutations to apply, in order, to selectors within the CSS. There are two types of mutations:

  • Prefix: A String selector to prefix all selectors with. html and body selectors are special cased by being replaced with the prefix.

  • Replace: Replace a selector or part of a selector with another selector. This uses String.replace() under the hood.

In this example, all of the selectors in foo.css will be prefixed with .foo:

grunt.initConfig({
  css_selectors: {
    options: {
      mutations: [
        {prefix: '.foo'}
      ]
    },
    your_target: {
      files: {
        'dest/foo-prefixed.css': ['src/foo.css'],
      },
    },
  },
})

In this example, all .pure in foo-pure.css selectors will be replaced with .yui3:

grunt.initConfig({
  css_selectors: {
    options: {
      mutations: [
        {search: /^\.pure/g, replace: '.yui3'}
      ]
    },
    your_target: {
      files: {
        'dest/foo-yui3.css': ['src/foo-pure.css'],
      },
    },
  },
})

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
