More on content-visibility
28.10.2020
Back in August 2020, when the content-visiblity property in CSS trickled its way into Chrome browsers, Una Kravets and Vladimir Levin wrote about it and we covered it. The weirdest part is that to get the performance value out of it, you pair it with contain-intrinsic-size on these big chunks...

Core Web Vital Tooling
26.10.2020
I still think the Google-devised Core Web Vitals are smart. When I first got into caring about performance, it was all: reduce requests! cache things! Make stuff smaller!

Vital Web Performance
21.9.2020
I hate slow websites. They are annoying to use and frustrating to work on. But what does it mean to be “slow”? It used to be waiting for document load. Then waiting for page ready. But with so many asynchronous patterns in use today, how do we even define what “slow” is? The W3C has […]
