Stylelint
Stylelint is a modern linter for CSS and CSS-like languages that helps developers avoid errors and enforce consistent coding conventions. It analyzes CSS, SCSS, Less, and other stylesheet files to detect potential issues, enforce style rules, and automatically fix many problems. The tool is highly configurable with built-in rules and supports custom plugins for specific needs.
Developers should use Stylelint to maintain clean, error-free, and consistent CSS codebases, especially in team environments where multiple people contribute to stylesheets. It's particularly valuable for large projects, design systems, and when using preprocessors like SCSS or Less to catch syntax errors, enforce naming conventions, and ensure accessibility best practices. The automatic fixing capability (via 'stylelint --fix') saves time by resolving common issues without manual intervention.
