Getting Started

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-css-wrap-2 --save-dev

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

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

The "css_wrap" task

Overview

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

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

Options

options.selector

Type: String Default value: ''

The selector of the css-wrapper

Usage Examples

Default Options

Wrap all rules in a css-file with a certain selector.

css_wrap: {
  options: {
    selector: '.my-app'
  }
  files: [{
    src: 'src/styles.css',
    dest: 'build/styles.css',
  }]
}

Wrap all contents of a release directory and add a .wrap.css extension

determine the selector based on a function of the filename

css_wrap: {
  options: {
    selector: function(src){
        // if the file name is release/css/baseline.css
        // then the selector will be '#baseline'
        var split_src = src.split('/');
        var file_name_parts = split_src[3].split('.');
        return '#' + file_name_parts[0];
    }
  }
  files: [{
    expand: true,
    cwd: 'release/css',
    src: ['*.css', '!*.min.css'],
    dest: 'release/css',
    ext: '.wrap.css'
  }]
}
