Two scrolling behaviors that I found odd on this page and on the NY Times example[1] on iOS:<p>- You can&#x27;t scroll to the top by tapping the status bar.<p>- The scrolling momentum is different. There&#x27;s less friction, as if you were scrolling through a list view (e.g. Mail).<p>Anyone know how&#x2F;why? I thought it might be some -webkit-overflow-scrolling trickery[2] with a full-size container div or something, but I don&#x27;t see anything too weird like that.<p>[1] <a href="https:&#x2F;&#x2F;amp.gstatic.com&#x2F;v&#x2F;mobile.nytimes.com&#x2F;2015&#x2F;10&#x2F;08&#x2F;us&#x2F;reassurances-end-in-flint-after-months-of-concern.amp.html?amp_js_v=0" rel="nofollow">https:&#x2F;&#x2F;amp.gstatic.com&#x2F;v&#x2F;mobile.nytimes.com&#x2F;2015&#x2F;10&#x2F;08&#x2F;us&#x2F;r...</a><p>[2] <a href="https:&#x2F;&#x2F;css-tricks.com&#x2F;snippets&#x2F;css&#x2F;momentum-scrolling-on-ios-overflow-elements&#x2F;" rel="nofollow">https:&#x2F;&#x2F;css-tricks.com&#x2F;snippets&#x2F;css&#x2F;momentum-scrolling-on-io...</a><p>EDIT: Turns out there <i>is</i> some -webkit-overflow-scrolling trickery going on[3].
