We use stylelint for CSS linting. stylelint catches syntax errors and helps you and your team stay consistent with modern CSS standards and conventions.
We've pre-configured it specifically for the boilerplate's styled-components setup (and following that package's recommendations).
However, you can (and should!) adapt it to your own style setup if you decide to modify it.
You can trigger stylelint using the npm run lint:css command or you can integrate with your IDE by downloading the relevant plugin. We recommend the latter.
