This feature will make your page only load necessary CSS files when the page is opened.
The rest of the CSS files (shown in green below) will be postponed and loaded asynchronously when the rest of the resources are loaded.
This will improve page load speed and also render speed because the browser normally waits for all CSS files to load before displaying your page.
To access this page:
- In the module main configuration, click the button “Async CSS”
- Click the button “Configure async CSS”
