A browser must process all your site’s stylesheets, which can cause delays in page loading. Inlining the Critical CSS (immediately needed styles) and deferring Uncritical CSS (styles needed later) can improve page load speed.
Recommendations
- Avoid any unnecessary styles such as duplicate styles via the WordPress Customizer.
- Set up critical CSS for above-the-fold content.
