Combine media queries

Combine matching media queries into one media query definition. Useful for CSS generated by preprocessors using nested media queries.

This was written as a solution to a problem we have using LESS CSS for our mobile first sites.

Getting Started

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-combine-media-queries --save-dev

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

grunt.loadNpmTasks('grunt-combine-media-queries');

The "cmq" task

  cmq: {
    your_target: {
      // Target-specific file lists and/or options go here.
    }
  }
})

  cmq: {
    options: {
      log: false
    },
    your_target: {
      files: {
        'tmp': ['test/*.css']
      }
    }
