Stylelint Config Generator - Online CSS Linter Setup

Stylelint is a powerful, modern CSS linter that helps you avoid errors and enforce consistent conventions in your stylesheets. It can catch mistakes like invalid hex colors, duplicate selectors, or unknown properties before they reach production, saving you debugging time and maintaining code quality across large teams.

Copy the JSON output into a .stylelintrc.json file in your project root, or reference it directly from your package.json. Then install the required presets (e.g., stylelint-config-standard) and run Stylelint via CLI or integrate it into your build tools like webpack, Gulp, or your code editor.

The Recommended preset (stylelint-config-recommended) only enables rules that catch possible errors. The Standard preset (stylelint-config-standard) extends recommended and additionally enforces common stylistic conventions (like indentation, quotes, spacing). Use Standard for a full‑featured starting point, or Recommended if you only want error checking.

Yes, you can provide an array of extends: "extends": ["stylelint-config-standard", "./my-custom-config"]. Later configs override earlier ones. This generator currently supports a single string, but you can manually edit the output file to add more.

Off disables the rule completely. Warning shows a warning but does not cause a non‑zero exit code (ideal for deprecations). Error is the default and will cause Stylelint to exit with an error code, which is useful for CI/CD pipelines.

You can add an ignoreFiles array in your Stylelint config to ignore whole directories or patterns. For inline ignores, use /* stylelint-disable-next-line */. This generator focuses on rules; add ignoreFiles manually after downloading the file.
