    Power Tools For The Web [Deprecated]

    Susy is Deprecated. It should no longer be used on new projects, and will no longer be receiving any updates.

    npm version

    Susy is a design-agnostic set of tools for creating powerful, custom layouts. We didn't want another grid system full of rules and restrictions — we wanted a power tool for building our own damn systems. Version Three is trimmed down to it's most basic components — functions that can be used to build any grid system.


    "I like the idea of grids-on-demand, rather than a strict framework."
    – Chris Coyier, CSS Tricks

    "Susy and Zendesk have been getting along magically… It’s precisely what you need and nothing more."
    — Stephany Varga, Zendesk

    "If you’re interested in reading Sass poetry, be sure to look at Susy’s source code!"
    — Kitty Giraudel, SitePoint


    Third-Party Tools


    npm install susy

    There are two imports to choose from. The default sass/susy comes with un-prefixed versions of the core API functions. If you want Susy to be name-spaced, import sass/susy-prefix instead.

    // un-prefixed functions
    @import '<path-to>/susy/sass/susy';
    // susy-prefixed functions
    @import '<path-to>/susy/sass/susy-prefix';

    Using Eyeglass

    With eyeglass set up, you can @import 'susy'; without providing the npm-modules path.

    Using Webpack

    Make sure sass-loader is installed:

    npm install sass-loader --save-dev

    Make sure you have sass-loader enabled in your webpack configuration:

    // webpack.config.js
    module: {
      rules: [
          test: /\.scss$/,
          use: ['style-loader', 'css-loader', 'sass-loader']

    Start using Susy:

    /* app.scss */
    @import "~susy/sass/susy";

    Using Gulp

    Add a gulp task:

    // gulpfile.js
    gulp.task('sass', function() {
      return gulp.src('scss/*.scss')
              outputStyle: 'compressed',
              includePaths: ['node_modules/susy/sass']
          }).on('error', sass.logError))

    Start using Susy:

    /* app.scss */
    @import 'susy';

    Using Grunt (and Yeoman)

    To add Susy to the Sass task, edit your Gruntfile.js at the root level of your project and look for the Sass-related rules. Add require: 'susy' inside the options object:

    // Gruntfile.js
    sass: {
      dist: {
        options: {
          style: 'expanded',
          require: 'susy'
        files: {
          'css/style.css': 'scss/style.scss'

    Assuming you’ve already installed Susy, it will now be added to the project and will not clash with Yeoman's grunt rules.

    Start using Susy:

    /* app.scss */
    @import 'susy';

    Susy vs Su

    You may notice that some functions have a susy- prefix, while others only have su-. This helps distinguish between the two distinct layers:

    • The core grid-math layer is called Su, and is made up of "pure" functions that expect normalized values. This is useful if you prefer argument-syntax to shorthand syntax, or if you are building your own Susy mixins.
    • The upper Susy layer provides syntax-sugar – global defaults, shorthand-parsing, normalization, and a smaller set of common-use functions that call on the core math as necessary. This is the primary API for most users.


    npm i susy
