If your animation is stuttering and you can’t tell whether it’s your math, your rendering, or just the browser being rude, this article is a solid cleanup pass.

It breaks down the usual performance traps without turning into a giant lecture, which is honestly rare.

I love when an animation perf article basically boils down to “stop making the browser do layout gymnastics every frame” and points people back to transforms/opacity. Half the “stutter” I see in the wild is just animating `top/left` (or box-shadow) and wondering why it feels like dragging a couch across carpet.

“dragging a couch across carpet” made me laugh because yeah, top/left and box-shadow always feel like that in devtools — have you found a reliable way to convince folks that “FPS looks fine” can still feel laggy when height/width (or even filter: blur) is chewing up layout/paint time? honestly not sure on that bit.
