mobile - iOS 7 Safari auto shrinking/hiding UI elements not working when scroll -

-

when scroll on web page in ios 7s safari url bar shrinks , bottom navigation bar disappears. in site working on these 2 things not happen.

the momentum/inertial scrolling not working until added -webkit-overflow-scrolling: touch; html element.

i can't imagine element have added code have lock mobile safari this.

hoping isn't repeat question, it's hard know call besides "shrinking/hiding".

i accidentally stumbled upon solution last night in article maximiliano firtman's article breaking mobile web. article points out many issues new mobile safari in ios 7.

the solution problem close answer (his being if there overflow: scroll; on page not trigger auto ui hide feature) mine overflow: hidden; style.
