Easy Critical CSS for WordPress

Easy Critical CSS is a lightweight WordPress plugin that lets you add Critical CSS to any page on your site to improve loading speed and performance.

Features:

– Easily add Critical CSS and Secondary CSS to any page

– Secondary CSS removes unused CSS rules and stylesheets, ensuring only a single optimized CSS file loads

– Supports posts, pages, archives, and taxonomy pages

– Fully compatible with caching plugins (WP Rocket, W3 Total Cache, WP Super Cache, etc.)

– Customizable settings for individual pages

– Stores Critical CSS in your choice of the database or as static files

– Optional API service (API key required) for automated Critical and Secondary CSS generation via CriticalCSS.net

– Background processing to generate CSS without blocking page loads or admin actions

Why Use Critical CSS? Critical CSS ensures above-the-fold content loads first by reducing render-blocking CSS. This helps you boost Core Web Vitals, improve page speed scores, and deliver a better experience to your visitors.

Want to try it out first? You can generate free one-off Critical CSS at CriticalCSS.net and manually apply it to your site using the plugin settings.
