Getting Started

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-unknown-css --save-dev

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

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

The "unknown_css" task

Detect undeclared CSS classes in your HTML.

Overview

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

grunt.initConfig({
  unknown_css: {
    all: {
      files: ['views/*.html', 'css/*.css']
    }
  },
})

This will parse all the class names from the css files in the css folder and match them with all the HTML files in the views folder. Any class name that's used in the HTML files, which doesn't exist in the CSS files, will be shown.

Options

options.whitelist

Type: Array Default value: []

A set of class names that should be allowed, even though they don't exist in the CSS files. You can also supply regexes here.

grunt.initConfig({
  unknown_css: {
    options: {
      whitelist: [ 'valid', /\{\{.*\}\}/ ]
    },
    all: {
      files: ['views/*.html', 'css/*.css']
    }
  },
})

The whitelist above will allow the use of the valid class, as well as classes such as icon-{{name}}.
