Optimizing Critical CSS for Lightning-Fast Rendering

CSS is a render-blocking resource; the browser will not paint pixels to the screen until all external stylesheets are fully downloaded and parsed.

Minifying stylesheets reduces byte transfer over the wire and speeds up First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

Frequently Asked Questions
