Apple Music has this “Spatial Audio” feature where the direction of the music in your headphones is based on the location of the device. It’s tough to explain just how neat it is. But that’s not what I’m here to talk about. I opened up the Apple Music app and saw a featured playlist of hit songs that support Spatial Audio....

This is a neat idea for a research project. The big map is fun, but the research had some tidbits in it worth looking at. The average favicon network request takes 130ms, at least from our speedy cloud instance. Fast, but not that fast, particularly for a file that nearly every website in the world has. All the more...

I’ve got some blind spots in CSS-related performance things. One example is the will-change property. It’s a good name.

The browser has long been a medium for art and design. From Lynn Fisher’s joyful A Single Div creations to Diana Smith’s staggeringly detailed CSS paintings, wildly creative, highly skilled developers have — over the years — continuously pushed web technologies to their limits and crafted innovative, inspiring visuals.

Maybe 1,000 icons is a little bit of an edge case, but hey, 250 rows of data with four icons in each gets you there. Tyler covers the nuances carefully in the post. The different techniques tested: inline <svg>,...

Many business websites need a multilingual setup. As with anything development-related, implementing one in an easy, efficient, and maintainable way is desirable. Designing and developing to be ready for multiple languages, whether it happens right at launch or is expected to happen at any point in the future, is smart. Changing...
