CSS is critical to rendering a page—a browser will not begin rendering until all CSS has been found, downloaded, and parsed—so it is imperative that we get it onto a user’s device as fast as we possibly can. Any delays on the Critical Path affect our Start Render and leave users looking at a blank screen. What’s the Big Problem?

FCP is a metric that measures the time between the point when a page starts loading to when the first bytes of content are rendered. The idea is that fetching assets that are part of that initial render earlier results in faster loading rather than waiting for other assets lower on the chain. Lazy loading other images.

Scott Jehl: One of the most impactful things we can do to improve page performance and resilience is to load CSS in a way that does not delay page rendering. That’s because by default, browsers will load external CSS synchronously—halting all page rendering while the CSS is downloaded and parsed—both of which incur potential delays. <link
