grunt-pixrem

Generate pixel fallbacks for rem units with Grunt.

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide which 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 the command:

npm install grunt-pixrem --save-dev

After the plugin has been installed, load it in your Gruntfile with:

grunt.loadNpmTasks('grunt-pixrem');

pixrem task

Run this task with the grunt pixrem command.

Grunt-pixrem is a CSS post-processor that generates CSS with pixel fallbacks or replacements for rem units. Check the browser data: if you want to use rem units and support < IE9, Opera Mini, or older Opera Mobile, this post-processor is for you.

For the node library, see node-pixrem.

Options

rootvalue

Type: String
Default: 16px

The root element font size. Can be px, rem, em, percent, or unitless pixel value.

replace

Type: Boolean
Default: false

Replace rules containing rems instead of adding fallbacks. Useful if you are generating a no-rem only stylesheet.

Usage examples

Add fallbacks with a root em value of 1.75em

grunt.initConfig({
  pixrem: {
    options: {
      rootvalue: '1.75em'
    },
    dist: {
      src: 'app/css/main.css',
      dest: 'dist/main.css'
    }
});

Create an IE8 / no-rem-support only stylesheet

grunt.initConfig({
  pixrem: {
    options: {
      rootvalue: '85%',
      replace: true
    },
    dist: {
      src: 'app/css/main.css',
      dest: 'dist/main.css'
    }
});
