Susy is Deprecated. It should no longer be used on new projects, and will no longer be receiving any updates.
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
- Susy.js CSS-in-JS port
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.
Make sure sass-loader is installed:
npm install sass-loader --save-devMake 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';Add a gulp task:
// gulpfile.jsgulp.task('sass',function(){returngulp.src('scss/*.scss').pipe(sass({outputStyle: 'compressed',includePaths: ['node_modules/susy/sass'],}).on('error',sass.logError),).pipe(gulp.dest('dist/css'));});Start using Susy:
/* app.scss */@import'susy';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';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.
At OddBird, we love contributing to the languages & tools developers rely on. We're currently working on polyfills for new Popover & Anchor Positioning functionality, as well as CSS specifications for functions, mixins, and responsive typography.
