Change Details

See * <http://www.slideshare.net/firt/extreme-web-performance-for-mobile-devices-54478615#slide=143> * https://developer.mozilla.org/en-US/docs/Web/CSS/touch-action Use of `touch-action: manipulation;` should improve touch-to-click and touch-to-sroll feedback on mobile browsers, which otherwise have to wait for a certain amount of time to disambiguate the touch, as well as triggering JavaScript events. I haven't confirmed this myself nor verified how much it improves perceived performance on affected devices. I imagine also that if we have any touch event handlers, this may not work as expected and require additional explicit declarations to opt-in to those. {F2958044 size=full}
