Best Practices
Prioritize Critical CSS
Inline the CSS required for above-the-fold content to improve perceived load time.
- Defer the loading of non-critical CSS to speed up initial rendering.
- Minify your CSS to remove whitespace and comments, and enable compression (Gzip/Brotli) on your server.
- Regularly purge unused CSS to keep your stylesheets lean.
