-webkit-overflow-scrolling: touch; breaks in Apple's iOS8

Question

I'm working on a web app that uses -webkit-overflow-scrolling:touch in several places to give the overflown divs inertia scrolling.

Since updating to IOS8, -webkit-overflow-scrolling: touch stops you being able to scroll whatsoever, and the only way I have been able to fix this so far is by removing -webkit-overflow-scrolling: touch which leaves the standard sticky scrolling. Please help!

Here is an example of one of the standard classes that works in iOS5, 6, and 7:

.dashboardScroll {
    height: 100%;
    overflow-x: hidden;
    overflow-y: scroll;
    -webkit-overflow-scrolling: touch; /*MAKES OVERFLOWN OBJECTS HAVE INERTIA SCROLLING*/
    -webkit-transform: translateZ(0px); /*HELPS THE ABOVE WORK IN IOS5*/
} 

Answer 1

I had a similar problem with a (quite complex) nested scrollable div which scrolled fine in iOS 5, 6 and 7, but that intermittently failed to scroll in iOS 8.1.

The solution I found was to remove all the CSS that tricks the browser into using the GPU:

-webkit-transform: translateZ(0px);
-webkit-transform: translate3d(0,0,0);
-webkit-perspective: 1000;

By doing this, the '-webkit-overflow-scrolling: touch;' can still be included and still function as normal.

It did mean sacrificing the (for me, dubious) gains to scrolling performance that the above hacks gave in earlier incarnations of iOS, but in the choice between that and inertia scrolling, the inertia scrolling was deemed more important (and we don't support iOS 5 anymore).

I cannot at this stage say why this conflict exists; it may be that it is a bad implementation of these features, but I suspect there is something a bit deeper in the CSS that is causing it. I am currently trying to create a pared down HTML/CSS/JS configuration to demonstrate it, but maybe the heavy markup structure and the large amounts of dynamic data is necessary for it to happen.

Addendum: I did, however, have to point out to our client that if even with this fix the user starts trying to scroll on a non-scrollable element she will have to wait a second after stopping before being able to scroll the scrollable element. This is native behaviour.

I had this problem and found a solution. The solution is that, you have to put your content into two containers for ex:(.dashboardScroll > .dashboardScroll-inner) and give the inner container ".dashboardScroll-inner" 1px more height than the parent ".dashboardScroll" throug this css3 property

.dashboardScroll-inner { height: calc(100% + 1px);}

check out this :

or otherwise if you can't add another container use this:

.dashboardScroll:after { height: calc(100% + 1px);}

I had the same problem in a Cordova web app. For me, the problem was that I had a parent <div> that was animated and had the property animation-fill-mode: forwards;

Removing this property solved the problem and fixed the broken overflow-scrolling.

Answer 4

I was not able to solve the problem with previous answers. So after a few hours a gave the iScroll library a try, iScroll. I know including an extra library (and quite sizable) to add scrolling for just iOS is not great but this is what worked for me. Just follow the readme, the lite version suffices.

Disadvantages:

• Scrolling on Android now looks like crap, it is not native anymore.
• It is not possible to refresh the page by scrolling anymore
• You need to apply another fix for Android : Clicks not working

I am unsure if I will use it, but if you are in need give it a go.

Answer 5

I tried every solutions here without success. I was able to make it work by having the property -webkit-overflow-scrolling: touch; on the scrollable div AND on the parent container.

div.container {
    -webkit-overflow-scrolling: touch;
}

div.container > div.scrollable {
    -webkit-overflow-scrolling: touch;
    overflow-y: auto;
}

Preventing touch events from surrounding elements bubbling up the DOM is another potential solution, you may notice that scrolling stops when surrounding DIV elements receive the touch or drag events. We had this particular issue in a menu that needed to scroll smoothly. Turning off those events helped stop the "sticking" of the scroll able element.

$html.bind('touchmove', scrollLock );

var scrollLock = function(e) {
        if( $body.hasClass('menu-open') ){
                e.stopPropagation();
                e.preventDefault();
        }
};

$html.unbind('touchmove', scrollLock );

Answer 7

I've been having some trouble with it too but in a slightly different scenario.

I do have my divs with inertia without any problems.

I have a simple JSFiddle where you can have a look.

https://jsfiddle.net/SergioM/57f2da87/17/

.scrollable {
    width:100%;
    height:200px;
    -webkit-overflow-scrolling:touch;
    overflow:scroll;
}

Hope it helps.

I used the last method in mohammed Suleiman's answer (.dashboardScroll:after { height: calc(100% + 1px);}) but the result was that I had a 100% + 1px empty space below my content. I fixed this by changing height back to 1px after 500ms. Ugly, but it works.

This was a react.js app so my code was like this:

componentDidUpdate() {
    if (window.navigator.standalone && /* test for iOS */) {
        var self = this;
        setTimeout(function(){
            self.refs.style.innerHTML = "#content::after { height: 1px}";
        }, 500);
    }
}

and render:

render() {
    var style = '';
    if (window.navigator.standalone && /* test for iOS */) {
        style = "#content::after { height: calc(100% + 1px)}";
    }
    return (<div>
                <style type="text/css" ref="style">
                    {style}
                </style>
                <div id="content"></div>
            </div>);
}

I had this problem while using the angular bootstrap modal. I fixed it by creating my own stylesheet and removing the fixed width and margin in the media queries.

ORIGINAL:

  .modal-dialog {
    position: relative;
    width: auto;
    margin: 10px;
  }

@media (min-width: 768px) {
  .modal-dialog {
      width: 600px;
      margin: 30px auto;
  }
    .modal-content {
        -webkit-box-shadow: 0 5px 15px rgba(0, 0, 0, 0.5);
        box-shadow: 0 5px 15px rgba(0, 0, 0, 0.5);
    }
    .modal-sm {
        width: 300px;
    }
}
@media (min-width: 992px) {
    .modal-lg {
        width: 900px;
    }
}

CHANGES:

.modal-dialog {
    margin: 0px;
    margin-top: 30px;
    margin-left: 5%;
    margin-right: 5%;
}

@media (min-width: 768px) {
    .modal-dialog {
        width: auto;
        margin-left: 10%;
        margin-right: 10%;
    }
    .modal-content {
       -webkit-box-shadow: 0 5px 15px rgba(0, 0, 0, 0.5);
       box-shadow: 0 5px 15px rgba(0, 0, 0, 0.5);
    }
}

@media (min-width: 992px) {
    .modal-dialog {
        width: auto;
        margin-left: 15%;
        margin-right: 15%;
    }  
}

i fixed my issue by adding some inline css to the scrollable div with jquery.. adding the css to the div after the dom is loaded makes scrolling work.

$('.lightbox__scrollable-content').css('overflow-y', 'scroll');

Answer 11

My problem was that the body had position:fixed that came from body-scroll-lock.js. Removed it and everything worked fine.
