Unused CSS Detector

About Unused CSS Detection

This tool analyzes your HTML and CSS to identify selectors that aren't being used. Removing unused CSS can significantly reduce file size and improve load times.

Important Notes

• • This tool analyzes static HTML - dynamic content may require different selectors
• • Pseudo-classes like :hover and :focus are conservatively marked as "used"
• • Always test your site after removing CSS to ensure nothing breaks
• • Consider using tools like PurgeCSS for production builds
• • Review unused selectors manually before removing them
