Primer CSS

The CSS implementation of GitHub's Primer Design System

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";
