A mighty, modern CSS linter and fixer that helps you avoid errors and enforce consistent conventions in your stylesheets.
Over one hundred and sixty built-in rules. Geared towards standard CSS syntax, these can:
Limit language features: e.g.:
calc()and level 4 selectors.
<style>tags (used by Vue and Web Components) and Markdown code fences.
With stylelint, it's easy to start linting your CSS:
Decide how you want to use stylelint:
Create your configuration object by either extending a shared config or crafting your own:
stylelint-config-recommended. We update the configs with each new release of stylelint, so it's easy to stay up to date. Both configs are geared towards standard CSS syntax. If you use non-standard syntax (like
@ifetc.) then you might want to use a community config designed for that syntax e.g.
stylelint-config-recommended-scss. The recommended config turns on just the possible error rules. The standard config builds on top of the recommended config by additionally turning on over 60 of stylelint's stylistic rules with sensible defaults. You can always override specific rules after extending either config. When using either config, you'll likely want to add (and configure to your specific needs) some of the rules that limit language features. Alternately, you can search for another community config and extend that instead.
To craft your own config, first learn about how rules are named and how they work together, then either:
null) the rules that you don't care to enforce.

stylelint follows semantic versioning. However, due to the nature of stylelint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, based on ESLint's semantic versioning policy we've defined the following semantic versioning policy for stylelint:
Patch release (intended to not break your lint build)
Minor release (might break your lint build)
Major release (likely to break your lint build)
According to our policy, any minor update may report more errors than the previous release (ex: from a bug fix). As such, we recommend using the tilde (
"stylelint": "~7.2.0" to guarantee the results of your builds.
