Optimize CSS file size

Large CSS files block rendering and increase the time it takes for the browser to construct the CSSOM, leading to a slower First Contentful Paint.

Quick Reference

• Keep individual CSS files small to speed up parsing and rendering
• Use minification and remove unused CSS (PurgeCSS)
• Leverage modular CSS or Tailwind to reduce duplication

Check

Audit the size of CSS files and identify those exceeding recommended limits (e.g., > 50KB gzipped).

Fix

Minify CSS, remove unused styles, and consider splitting large stylesheets into smaller, page-specific files.
