Terra Stylelint Shared Config

NPM version License Build Status Dependencies status devDependencies status

This repo is archived and active development has moved to terra-toolkit.

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 browsers being targeted. Terra's targeted browsers are specified by the browserslist-config-terra module.

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 stylelint-config-terra --save-dev



  "stylelint": {
    "extends": "stylelint-config-terra"

Extending Terra's Configuration

It is possible to specify and override the rules defined by stylelint-config-terra. Read more about it here.

For example, it is possible to override the browsers specified to the no-unsupported-browser-features plugin.

    "extends stylelint-config-terra",
    "rules": {
      "plugin/no-unsupported-browser-features": [
        "browsers": ["iOS >= 10"],
        "severity": "warning",
