原文外掛簡介
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.
External services
This plugin interacts with external third-party services in order to provide its functionality. Below is a detailed breakdown of these interactions:

Kinsta Cache Clear (localhost)
If your site is hosted on Kinsta, this plugin can trigger a cache clear after generating new critical CSS, ensuring immediate availability of updated styles.
