Yup - if it's possible to scroll, then we have to (a) pay attention to the elements "below the fold", even if they'd otherwise be ignorable, and (b) paint at least some of the off-screen stuff, so that it'll be smooth if you start scrolling. Even if you never scroll at all, as long as it's *possible* to do so, such as in "overflow:hidden", you incur some of these costs. If you want to scroll via JS, don't use 'contain', just use "overflow:hidden". ~TJReceived on Tuesday, 3 December 2013 02:38:52 UTC
