Answer

Optimizing CSS delivery is crucial for improving rendering speed and enhancing user experience. By minimizing render-blocking CSS, you can ensure faster page loads and better performance metrics.

<!-- BEGIN COPY / PASTE -->
    <link rel="preload" href="styles.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
    <noscript><link rel="stylesheet" href="styles.css"></noscript>
    <!-- END COPY / PASTE -->

Additional Comment:

Preload critical CSS to ensure it is available as soon as possible without blocking rendering.
Use media queries to load non-critical CSS conditionally, reducing initial load time.
Consider inlining critical CSS directly in the HTML to eliminate additional requests.
Minify CSS files to reduce their size and improve download speed.
Use a content delivery network (CDN) to serve CSS files from locations closer to users.
