A mighty CSS linter that helps you avoid errors and enforce conventions.
Features
It's mighty as it:
has over 100 built-in rules for modern CSS syntax and features
supports plugins so you can create your own custom rules
automatically fixes problems where possible
supports shareable configs that you can create or extend
can be customized to your exact needs
has 15k unit tests making it robust
is trusted by companies worldwide like Google and GitHub
And it can be extended to:

How it'll help you
It'll help you avoid errors, for example:
invalid things, e.g. malformed grid areas
valid things that are problematic, e.g. duplicate selectors
unknown things, e.g. misspelled property names
And enforce conventions, for example:
disallow things, e.g. specific units
enforce naming patterns, e.g. for custom properties
set limits, e.g. the number of ID selectors
specify notations, e.g. for modern color functions
We recommend using a pretty printer like Prettier alongside Stylelint. Linters and pretty printers are complementary tools that work together to help you write consistent and error-free code.
