Primer
Primer CSS is the Sass implementation of Primer, the design system that powers GitHub.
Migrating
🚨 If you currently use the primer or primer--prefixed npm packages, please read the migration guide!
Install
This repository is distributed with npm. After installing npm, you can install @primer/css with this command:
$ npm install --save @primer/css
Usage
The included source files are written in Sass using SCSS syntax. After installing with npm, you can add your project's node_modules directory to your Sass include paths (AKA load paths in Ruby), then import it like this:
@import "@primer/css/index.scss";
You can import individual Primer modules directly from the @primer/css package:
@import "@primer/css/core/index.scss";
@import "@primer/css/product/index.scss";
@import "@primer/css/marketing/index.scss";
