Indicating Scroll Position on a Page With CSS

24.3.2020
Scrolling is something we all know and do on the web to the extent that it’s an expectation or perhaps even a habit, like brushing our teeth. That’s probably why we don’t put too much thought into designing the scrolling experience — it’s a well-known basic function. In fact, the popular “there...

I've had a number of browser tabs open to articles all related to web performance and gosh darn it if blogging them is a way for me get some closure. They are all good! Manuel Matuzovic, Why 543 KB keep me up at night: Yes, I know, it depends. 543 KB aren't always bad, but on that specific page...

CSS Can Influence Screenreaders

23.3.2020

What Does `playsinline` Mean in Web Video?

18.3.2020
I got myself confused about this the other day, went around searching for an answer and came up empty on finding something clear. The answer actually is quite clear and I feel a little silly for not knowing it. With it in place, like this: <video src="..." controls playsinline</video Mobile...

Playing With Particles Using the Web Animations API

18.3.2020
