Hardest problem in computer science: centering things

First time probably ever that I've had to disable Javascript because of the creepy and distracting mouse thing. It really feels like you're invading other people's privacy, and if it doesn't, having things randomly move across your field of vision makes it difficult to read.

Is the author here? Can you give us a toggle so we can turn off the moving cursors? It's a little distracting. Reader mode isn't working so well, so I deleted the element in developer tools in the mean time.

Ha, excellent. This needs a Wat video. I heard the sound in my head on every misalignment.

You're being downvoted, but here's an upvote from someone who also found this annoying. Confusing at first, then annoying once I saw what was happening.

I'm out of the web development game, but in my day it was still quite possible to vertically center text and icons consistently. You just had to notice it was busted in the first place, and then go in and fix it. It's not a technological problem, or at least not a non-trivial one.

The problem is that, if it's off by a couple pixels, the front-end engineer may not notice it, and the designer may not even look at it. Or, if they do notice it, they think "do I want to file a bug report right now, or do I want to work on my own ticket right now?" Having worked in both roles, this is my experience anyway.

I agree that there's no consistent way to center things that always works, no matter what, without anybody thinking about it or paying really careful attention. I think we prioritize solutions with those performance characteristics, which is a separate problem of even greater magnitude.
