This plugin requires Grunt ~0.4.0

npm install grunt-autoprefixer --save-dev

grunt.loadNpmTasks('grunt-autoprefixer');

The "autoprefixer" task

Overview

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

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

Options

options.browsers

Type: Array Default value: ['last 2 versions']

You can specify browsers actual for your project (by default, it’s "last 2 versions"):

autoprefixer.compile(css, ["last 1 version", "> 1%", "ie 8", "ie 7"]);

• last n versions is last n versions for each browser (for example, Google also uses “last 2 version” strategy).
• > n% is browser versions, which global usage statistics is more than n%.
• You can also set browsers directly.

Usage Example

Default Options

    },
    files: {
      'dest/styles.css': ['src/something.css', 'src/whatever.css']
    },
  },
