Primer is the CSS framework that powers GitHub's front-end design. Primer CSS includes 23 packages that are grouped into 3 core meta-packages for easy install. Each package and meta-package is independently versioned and distributed via npm, so it's easy to include all or part of Primer within your own project.
The Primer CSS repo is managed as a monorepo that is composed of many npm packages.
$ npm install --save primer-css
The source files included are written in Sass (
scss) You can simply point your sass
include-path at your
node_modules directory and import it like this.
You can also import specific portions of the module by importing those partials from the
/lib/ folder. Make sure you import any requirements along with the modules.
For a compiled CSS version of this module, a npm script is included that will output a CSS version to
build/build.css The built CSS file is also included in the npm package.
$ npm run build
