Eliminate Render Blocking

By default, CSS and JavaScript elements are considered render blocking, which means the browser won't render any processed content until the resource is downloaded and executed. To reduce the impact of render-blocking resources, critical codes are inlined into the page and the non-critical codes are deferred.

Eliminate CSS Render Blocking

The Optimize CSS Delivery eliminates CSS render blocking by automatically identifying the critical CSS that is required to render the section of the page above the fold on each page and inlines it in the <head> section of the HTML document. The combined CSS files are then loaded asynchronously using the preload link.

You can easily enable the Optimize CSS Delivery feature in the Basic Features section on The Dashboard .
