Momentum Scrolling FTW!

The mobile experience for this page is responsive via relative sizing, images (such as they are) and media queries, but from Safari on iOS there was a distinct lack of snappiness in scrolling leading to a stagnant feeling. We must bring back the bounce!

‘Inertial’ or momentum scrolling is easily enabled with the CSS property -webkit-overflow-scrolling.1

Thanks to an article from CSS Tricks2, this was a simple matter of adding two lines to the body selector.

  overflow-y: scroll; /* has to be scroll, not auto */
  -webkit-overflow-scrolling: touch;

Page scrolling from mobile, that is to say, from iOS WebKit, now has the familiar bounciness. Cross-browser behavior at least from the point of view of device mode in Chrome Dev Tools seems to be looking A-OK as well.
