Interesting CSS hack I wrote this week: apparently some elements are rendered differently during a transition - I noticed it as a small "jiggle" on my site's nav icons... (setting "backface-visibility" to "hidden" on the transformed element prevents the jitter)

I suppose the browser doesn't know when the back of an element is visible if animating a transform property, but does in a static position? (causing the jitter when it starts/ends)

Anyway, I have smooth un-jittery nav icons now. Just in case anyone was wondering how I did that.

(I know this seems trivial, but you have no idea how long I'd been searching for this fix - really, CSS is hard)
