This plugin requires Grunt ~0.4.5

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-split-images --save-dev

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

grunt.loadNpmTasks('grunt-split-images');

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

grunt.initConfig({
  split_images: {
    options: {
      output: 'dist/styles.images.css'
    },
    files: {
     'dist/styles.css': ['dev/styles.css']
    },
  },
});

Type: String Default value: ''

File in which to put the image declarations. A string value which needs a path and filename (eg. in dist/styles.images.css).

In this example, the default options are used to get two files which are generated to the specific folder. So if the dev/styles.css file has the content

a.top {
  background-repeat: no-repeat;
  background-image: url("data:image/svg+xml;charset=US-ASCII,%3C%3Fx.....");
}

the generated result would be that there are now two files. One which has the standard styles, the second with your image:

styles.css

a.top {
  background-repeat: no-repeat;
}

styles.images.css

a.top {
  background-image: url("data:image/svg+xml;charset=US-ASCII,%3C%3Fxml%20v.......");
}

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.
