# Lint CSS and SCSS files

CSS linting catches syntax errors, enforces consistent coding standards, and prevents maintainability issues before they reach production.

## Quick Reference

- Install Stylelint with stylelint-config-standard
- Add SCSS support with stylelint-config-standard-scss
- Enable auto-fix in your IDE and pre-commit hooks
- Include in CI/CD pipeline to catch issues early

## Check

Set up CSS/SCSS linting tools like Stylelint to automatically detect syntax errors, enforce coding standards, and maintain consistent code quality.

## Fix

Configure Stylelint with appropriate rules and integrate it into your build process and code editor for real-time error detection and fixing.

## Explain

Explain how CSS linting prevents errors, enforces consistent coding standards, and improves maintainability of stylesheets across the team.

## Code Review

Review stylesheets, component styles, and responsive states related to Lint CSS and SCSS files. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
