  • Paul Lewis writing for HTML5 Rocks, Avoiding Unnecessary Paints:

    What happens if I scroll and I happen to move the mouse at the same time? It's perfectly possible for me to inadvertently "interact" with an element as I scroll past it, triggering an expensive paint. That, in turn, could push me through my frame budget of ~16.7ms (the time we need to stay under that to hit 60 frames per second). I've created a demo to show you exactly what I mean. Hopefully as you scroll and move your mouse you'll see the hover effects kicking in, but let's see what Chrome's DevTools makes of it…
