What's the best way to reduce render-blocking CSS on my site?

Asked on Nov 17, 2025

Answer

Reducing render-blocking CSS is crucial for improving page load speed and enhancing the user experience. This can be achieved by optimizing how CSS is delivered and loaded in the browser.

Example Concept: To reduce render-blocking CSS, you can use techniques such as inlining critical CSS for above-the-fold content, deferring non-critical CSS, and using the "media" attribute for conditional loading. These methods allow the browser to render the visible part of the page faster while loading additional styles asynchronously.

Additional Comment:

Identify critical CSS that affects the initial viewport and inline it directly in the HTML.
Load non-essential CSS using the "media" attribute or "async" techniques to prevent blocking rendering.
Consider using tools like Critical or Penthouse to automate the extraction of critical CSS.
Regularly audit your CSS to remove unused styles and reduce file size.
