I have problem scrolling with touch scrolling, it's working just fine with mouse and keyboard arrows but not by touching.
This is the html code:
<div class="drive-dashboard">
<div id="dashboardContainer" class="dashboard-container"/>
</div>
And this is the CSS part
.drive-dashboard {
height: 100%;
width: 100%;
position: absolute;
overflow: auto;
}
Any suggestions where the problem is?
I've run into this before and in React i've been able to solve it with something like:
`document.addEventListener("touchstart", function() {}, true);`
But, I have to admit sometimes i've needed to use it and sometimes not, so I am not sure which html elements respond and which don't.
Here is some reference

I'm a bit confused about this but I think I've found the issue.
I have in my html:
<div class="dropdownz">
<button>HOVER_OR_CLICK</button>
<div class="dropdownz-content">
</div>
</div>
In my css I have:
.dropdownz {
float: left;
overflow: hidden;
}
.dropdownz-content {
display: none;
position: absolute;
z-index: 1;
}
.dropdownz:hover .dropdownz-content {
display: block;
position: fixed;
top: 50px;
}
So this basically means if I hover over the dropdownz class, the dropdownz-content display converts from none to block and the menu items show.
When I run this on an android touchscreen mobile device, I have to CLICK the dropdownz item in order for it to effect the hover and show the list, if I click it again, it effectively removes the hover.
This is desirable behaviour, it means I don't have to do any extra stuff for touch-screens. A "hover" becomes a click and the 2nd click removes the "hover". Great!
Apparently this doesn't work the same in SAFARI on an iPhone. I can't test it myself, I'm going via a friend who says it's not working, so I basically want to know:
Is this a known issue and what's the best way to remedy it? (Without JavaScript, surely!)
I'm thinking along the lines of :focus ?
try this :
.dropdownz:hover .dropdownz-content,
.dropdownz:active .dropdownz-content,
.dropdownz:focus .dropdownz-content{
display: block;
position: fixed;
top: 50px;
}
I have an element that overlays another element. The main element is a canvas where elements constantly have mouse interactions and the element directly overtop of it just shows elements that act as little markers. Same position, same size and it's important the overlay is overtop of the canvas.
What would it mean to make this "overlay" only exist visibility wise? As in having no possible user input because for its purposes it's not really there to be interacted with, just showing something.
Removing selection in CSS stops you from clicking on it but it's still overtop of the other element and doesn't allow mouse events. Hiding the element removes its presence but also makes it invisible.
In a normal desktop application you would just draw something to the screen and add functionality if you wanted but with HTML those two things are inherently the same.
I believe adding in the CSS the following code solves your issue:
.no-interaction {
z-index : -5
}
OR
.interaction {
z-index : 5
}
Turns out all it took was setting the pointer-events CSS attribute to none on whatever you want to have no presence.
I figured it would be a little more interesting than that, but there's a built in way in CSS.
<div id="canvas"></div>
<div id="overlay"></div>
#canvas, #overlay {
width: 500px;
height: 500px;
position: absolute;
}
#canvas {
background: blue;
}
#overlay {
background: red;
pointer-events: none; // right here
}
$('#canvas').click(function() {
alert('Clicked');
});

I am having some issues with a scrollable div on iOS. When trying to scroll by touching outside an input, it scrolls ok without any problem but when I try to scroll and I touch an input to start scrolling (there are a lot of chances that it happens because it is a div with a lot of inputs) it scrolls the whole window instead scrolling the div. I don't have that problem either in desktop or Android. I found a similar question (iOS HTML Input Tag Stops Scrolling in Scrollable Element) but it doesn't have any answer either. While I don't find any good solution, I decided to prevent the event touchmove when the user touches an input, but it is not exactly what I want.
Maybe someone already faced this problem and can help. I would really appreciate it, thanks in advance.
To get native momentum scrolling on iOS 5+, you'll need:
div {
overflow: scroll;
-webkit-overflow-scrolling: touch;
}
Source: Overflow
Maybe you also need:
div > * {
-webkit-transform: translateZ(0px);
}

This stuff made me crazy too, after testing everything, I found the following answer from Thomas Bachem here working and made it simpler in jquery.
Just add a class scrollFix to the inputs and you are ready to go. (or directly apply that js to any inputs/textarea using$('input, textarea')
Now when you touch and scroll on an input on iOS 8+, the input get all its "pointer-events" disabled (including the problematic behavior). Those "pointer-events" are enabled when we detect a simple touch.
$('.scrollFix').css("pointer-events","none");
$('body').on('touchstart', function(e) {
$('.scrollFix').css("pointer-events","auto");
});
$('body').on('touchmove', function(e) {
$('.scrollFix').css("pointer-events","none");
});
$('body').on('touchend', function(e) {
setTimeout(function() {
$('.scrollFix').css("pointer-events", "none");
},0);
});
Hacky workaround, but by doing this I was able to make scrolling work even on form inputs. The JS forces a reflow in the rendering engine, which is where the bug in iOS8 Safari lies. Changing the height to auto also improved scrolling when focused on a form element, since scrolling is forcibly handled by the browser when focused.
Markup:
<div class="modal-backdrop-container">
<div class="modal-backdrop">
<div class="modal> <!-- Content --> </div>
</div>
</div>
CSS:
.modal-backdrop-container {
z-index: 10;
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
height: 100%;
}
.modal-backdrop {
z-index: 10;
height: 100%;
background-color: rgba(255,255,255,0.5);
overflow: auto;
overflow-x: hidden;
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
}
.modal {
position: relative;
width: 400px;
max-width: 100%;
margin: auto;
background-color: white;
}
JS:
// reflow when changing input focus
$modalInputs = $('.modal').find(':input');
modalInputs.on('focus', function() {
var offsetHeight = modal.$backdrop[0].offsetHeight;
modal.$backdropContainer.css({
'height': 'auto'
});
});
modalInputs.on('blur', function() {
var offsetHeight = modal.$backdrop[0].offsetHeight;
modal.$backdropContainer.css({
'height': ''
});
});
Not sure of the var offsetHeight = modal.$backdrop[0].offsetHeight; line is needed, since both this and changing the height value should force a reflow.
I'm not able to click links inside a div the is position:absolute. It seems to not work on mobile android as it works fine on the desktop in Chrome and even ie8.
As soon as I remove the style it works. The class msg-inner is only for jQuery which has it scrollTop no styling on it. I've read many answers and to use z-index or position:relative on the inner div but none works. I even tried using position:fixed on msg_container and same problem. The inner div scrolls and everything looks right but just the links are broken, BTW sporadically some will work and some don't. I took away all styling and just put plain links inside to see if it was a format issue and still nothing.
<div id="msg_container" class="absolute" style="overflow-y:auto;width:100%;height:75%">
<div class="msg_inner">
.... stuff in here with links
</div><!--msg inner-->
</div><!--msg_container-->
CSS
.absolute {
position: absolute;
}
Your #msg_container shouldn't have a position of absolute, the .msg_inner should. Try this:
HTML
<div class="msg_container">
<div class="msg_inner">
.... stuff in here with links
</div><!--msg inner-->
</div><!--msg_container-->
CSS
.msg_container {
position: relative;
width: 400px;
height: 400px;
}
.msg_inner {
position: absolute;
top: 0px;
left: 0px;
}
Also note that I made msg_container a class, not an ID. It's considered bad practice to have multiple ID's of the same name. While I don't know your code of course, I assumed that you might have multiple msg_containers on a page... so I used a class instead.
I have an app built on Cordova and on some of my pages I am able to scroll horizontally out of my content into white space.
This is weird as I have nothing there that extends beyond my #wrapper, which is set to width: 100%.
So I was wondering if there was a way I could disable horizontal scrolling in the app altogether?
UPDATE:
Code on page as requested:
body {
background-color: #fff;
font-family:Arial, Helvetica, sans-serif;
color: #b7b8b9;
height: 100%;
width: 100%;
}
iframe{
border: none;
width: 100%;
/*margin-top: 50px;*/
}
#header{
height: 50px;
width: 100%;
}
<body>
<div id="wrapper">
<div id="header">
<div class="headerback">Home</div>
<div class="headerrefresh"><script>var pathname = window.location.pathname;</script><script>document.write('Refresh')</script></div>
<div class="headertitle"><h2>Get the Look</h2></div>
</div><!--HEADER-->
<iframe src="http://www.mbff.com.au/getthelook"></iframe>
</div>
</body>
Try to debug your page in Chrome (webkit) with the exact dimensions of your device. This solves most rendering issues for me.
I do not know the specific issue here, but it looks like one of your elements is flowing outside of the wrapper. You could for example try this in your css:
div.wrapper { overflow: hidden; width: inherit; }
Although it might be a better idea to find out why your page is expanding horizontally?
I was looking for the solution to this problem for a long time.
Finally I solved it in the following way.
I set style for bodyand html tags:
position: fixed;
width: 100%;
height: 100%;
overflow: hidden;
After that I've added div to body and set the style for it:
overflow-y: auto;
height: 100%;
So, I have got fixed body, which contains div with vertical scroll bar.
// Phone Gap disable only horizontal scrolling in Android.
// Add this code in your Phone Gap Main Activity.Initially Declare the variable
private float m_downX;
//Then add this code after loadUrl
this.appView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN: {
// save the x
m_downX = event.getX();
}
break;
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_CANCEL:
case MotionEvent.ACTION_UP: {
// set x so that it doesn't move
event.setLocation(m_downX, event.getY());
}
break;
}
return false;
}
});
Try adding the following code to your .html file:
document.body.addEventListener('touchmove', function(event) {
event.preventDefault();
}, false);
For the sake of completeness, I thought the answer which makes use of the official method of doing such a thing via the preference tag should be added:
<preference name="DisallowOverscroll" value="true"/>
Supported by Android and iOS according the documentation.
Default: false
Set to true if you don't want the interface to display any feedback when users scroll past the beginning or end of content. On iOS, overscroll gestures cause content to bounce back to its original position. on Android, they produce a more subtle glowing effect along the top or bottom edge of the content.
In my case it was broken styling like below
<body>
<div style="margin-left:5%; width:100%">Content</div>
</body>
which cause div to became horizontally bigger than body. I could see scroll when app run in browser. Set width to 90% (as it was initially intended) fixed the problem.
Generally, as it already pointed out here, enough to find element with wrong style which makes your page expanding horizontally and fix it.
BTW DisallowOverscroll was not helpful in above case.
