Grunt wrapper for criticalcss
This plugin requires Grunt ~0.4.2
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-criticalcss --save-devOnce the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-criticalcss');In your project's Gruntfile, add a section named criticalcss to the data object passed into grunt.initConfig().
grunt.initConfig({
criticalcss: {
custom: {
options: {
// Task-specific options go here.
}
}
},
