Builder Critical CSS Tools provides developer-friendly controls to:
<ul>
<li>Clear builder static CSS caches (Divi supported via its internal cache API)</li>
<li>Trigger a safe Critical CSS workflow by clearing caches and optionally warming key URLs</li>
<li>Show a reminder when site changes likely require regeneration</li>
<li>Record evidence: last regeneration trigger time and cache warming completion time</li>
</ul>
This plugin does not replace your builder’s performance engine. On Divi sites, clearing static resources typically prompts Divi to regenerate generated CSS (including Critical CSS) as pages are requested.

Tools to clear builder CSS caches and manage Critical CSS workflows on builder-based themes (including Divi).

This plugin will automatically have the CriticalCSS.com web service get the needed above the fold CSS for every page on your site to help improve your user experience and site speed. This is commonly required by google pagespeed as one of the last steps to do.
This plugin alone will not improve site performance. You need a minify and/or caching plugin as well.
This plugin does not handle any minification or re-ordering of assets. I recommend using <a href="https://wp-rocket.me/" rel="nofollow ugc">WP Rocket</a> with my <a href="https://wordpress.org/plugins/rocket-footer-js/">WP Rocket Footer JS</a>, <a href="https://wordpress.org/plugins/rocket-async-css/">WP Rocket ASYNC CSS</a>, and the plugin <a href="https://wordpress.org/plugins/the-preloader/">Preloader</a>
