Eliminate Render Blocking Resources
What does Eliminate Render Blocking Resources mean?
The result is a delay in the display of the content to the visitor, during which time the page may appear blank or incomplete.
Eliminating render-blocking resources is essential to minimize this delay so the page can load and display content as soon as possible.
How WP Rocket can help
Render blocking CSS
WP Rocket has a feature called “Optimize CSS Delivery” which generates the critical path CSS needed to render the visible part of your website and load all the other CSS files asynchronously, that’s deferred, without render-blocking.
You’ll find this feature under Dashboard → WP Rocket → Settings → File Optimization → Optimize CSS Delivery.
Tip: Open your website page source and search by “rocket-critical-css” to have sure that this feature is working properly.
If no "rocket-critical-css" was found, try to Regenerate the Critical CSS path.
Pagespeed is still flagging jquery.js on render-blocking.
Remove the line and make sure that your website is working fine. If so the recommendation will be satisfied.
If you don’t find the exclusion there, it means it’s being excluded automatically as part of compatibility. That means that the site would break otherwise.
