Prioritizing critical CSS is essential for improving render times and enhancing the user experience. Critical CSS refers to the styles required to render the above-the-fold content of a webpage immediately.

Example Concept: Critical CSS involves extracting and inlining the necessary CSS for above-the-fold content directly into the HTML document. This reduces render-blocking resources by ensuring that essential styles are available immediately, allowing the browser to paint the visible portion of the page faster. Non-critical CSS can be loaded asynchronously or deferred to improve overall page speed.

Additional Comment:

Use tools like Critical or Penthouse to automate the extraction of critical CSS.
Inline critical CSS directly in the HTML document's section to eliminate render-blocking.
Load non-critical CSS asynchronously using the "media" attribute or JavaScript.
Regularly update critical CSS as the design and structure of your webpage change.
