What It Does

This plugin is deprecated and will be removed in the future. It was coded back in 2019 when WP Rocket did not have asynchronous support for CSS. Although this plugin operates at a lower level, which helps apply loadCSS to all styles, we recommend using WP Rocket's system instead.

This is a simple high-performance plugin to enhance WP Rocket's CSS output to use the loadCSS preload polyfill. This will ensure any CSS being loaded via the page output is deferred and utilizes a preload attribute. Note: This will not affect admin pages. It is designed only to process front-end pages.

It is recommended to enable the WP Rocket setting for 'Optimize CSS', which provides your pages with inline Critical-CSS to avoid an unstyled flash on page load.

This plugin will boost your Lighthouse and PageSpeed Insight scores.

We hope that WP Rocket will implement this as a feature of their plugin. The existing Load CSS Asynchronously only works for supported wp_enqueue styles, which not all plugins/themes properly utilize. For normal users, we recommend using WP Rocket's system instead of this plugin.

Requirements include enabling WP Rocket's setting for 'caching for Logged-In Users' if you want logged-in users to see the effect. You can also run the plugin without WP Rocket.

Features include FilamentGroup's LoadCSS inline injector and a high-performance Regular Expression approach to process WP Rocket's output buffer.

No fluff. Just a robust loadCSS implementation.
