Stylelint Config Terra

NPM version Build Status

This configuration reflects Terra's supported stylelint policy for their UI library stylesheets. It extends the stylelint-config-sass-guidelines configuration which is based on sass-guidelines. Additionally, this configuration utilizes the stylelint-no-unsupported-browser-features plugin to check if the styles used are supported by the local browserslist being targeted.

What is Stylelint?

Stylelint is a mighty, modern CSS linter and fixer that helps you avoid errors and enforce consistent conventions in your stylesheets.


Install the module

$ npm install stylelint --save-dev
$ npm install @cerner/stylelint-config-terra --save-dev



  "stylelint": {
    "extends": "@cerner/stylelint-config-terra"
