TIL: Zooming into this animated div crashes Safari on iOS 14.2
A Hacker News user noticed that zooming on a page crashes their iPhone to the lock screen.
I was curious to see what the actual crashing element was, and narrowed it down to a single div with a CSS animation. I reproduced it on Codepen.
If you zoom in and out of that animated glow on an iOS 14.2 device, you should crash briefly to a black screen and then to the lock screen. I don't think there's any lasting harm, but try at your own peril.
It would be interesting to bisect the animation further to find out the part that is actually responsible of the crash.
