2. Run an Audit: Click the Run Audits button to initiate a comprehensive analysis of your project.
3. Unused CSS Detection: Under the Web Page Performance category, look for the Remove unused CSS rules item. Chrome will automatically scan all CSS files in your project and identify any unused selectors.
