Take this markup, stick it in an html file, and view it in mobile Safari on an iPad. I'm using an iPad Mini 4 on iOS 9.3.2.

So basically we have 4 absolutely positioned divs for showing where you are on the page, inside a very tall div (.page-scroll), which is inside a relatively positioned div with overflow-y: scroll and -webkit-overflow-scrolling: touch (.page-container). The other parent divs (page-viewport and viewport) are there to ensure a consistent look across devices.
On every other device we've tried, swiping to scroll scrolls the page-scroll div inside the page-container div as expected. However, on iPad, we are seeing non-deterministic behavior. If you swipe quickly, the page scrolls normally, but if you swipe slowly, the page will sometimes rubberband. It's as if the touchstart event is getting sent to one of the parent divs, and so the iPad thinks it is at the bottom or top of the page.
However! If -webkit-overflow-scrolling: touch is removed from the .page-container div, the problem disappears. But you lose momentum scrolling, which sucks. I should also note that if this markup is loaded onto a page via an iframe, the problem goes away, but that is not really an option for us (because reasons).
I have tried the suggestion in this similar question to put yet another div inside .page-scroll and set height: calc(100% + 1px), but that did not fix the bug.
I do see a lot of related questions that indicate -webkit-overflow-scrolling: touch has a myriad of problems, but none of those questions are quite exactly this bug, I think.
Has anyone encountered this before? Any suggestions for workarounds?

When i load the screen on iOS scrolling in the X axis is not possible on iOS. No issues on android. When clicking a button which refreshes the data on the screen scrolling is possible again.
Anybody an idea what could cause this?
<div class="container">
<!-- CONTENT -->
<div class="scroll-container">
<!-- CONTENT-->
</div>
</div>
CSS
.container {
overflow-y: scroll;
width: 100%;
position: absolute;
overflow-x: scroll;
}
.scroll-container {
min-width: 100%;

According to the docs you can add a scrolling section in your content using ion-scroll:
ion-scroll
Scroll is a non-flexboxed scroll area that can scroll horizontally or
vertically. ion-scroll Can be used in places where you may not need a
full page scroller, but a highly customized one, such as image scubber
or comment scroller.
<ion-scroll scrollX="true" scrollY="true">
<!-- ... -->
</ion-scroll>
Demo source:
<ion-header>
<ion-navbar>
<ion-title>Scroll</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<ion-scroll scrollX="true" scrollY="true" style="width: 100%; height: 100%">
<div class="map-div"></div>
</ion-scroll>
</ion-content>
<style>
.map-div {
width: 2600px;
height: 1400px;
background: url('./assets/map.jpeg') no-repeat;
}
</style>
I know there seems to be a lot out there about this, but none of the solutions seem to fix my issue.
I am trying to apply a fixed button to the bottom of my screen within an iframe. With my current implementation, I am experiencing a terrible flicker with the button on iOS Safari whenever I scroll.
Here's essentially what I have:
HTML
<iframe>
<body>
<div class="app">
<div class="app-content">
<div class="card">
<h1>Header</h1>
<p>Content</p>
</div>
<button class="fixed-button">This is flickering</button>
</div>
</div>
</body>
</iframe>
CSS
iframe {
border: none;
position: absolute;
height: 100%;
width: 100%;
top: 0; left: 0;
}
app {
-webkit-overflow-scrolling: touch;
overflow:auto;
position:absolute;
width:100%;
height:100%;
}
fixed-button {
position: fixed;
bottom: 1rem;
}
I've got a WIP on my site here http://jaredrauh.com/iframe-fixed-elements-ios/. Any suggestions would be amazing.
Page A has an iframe (that loads Page B). That Page B has a div#OutputDiv. My goal is to make that div in that iframe scrollable.
SOLUTION (CREDIT TO STEVE!):
Include overflow: auto for that div. However you must specify height too. Simply give any fixed value. eg height: 0.
Use a javascript function to make the div's height always same as the window's, even after window resize. height is now not fixed.
Code:
#outputDiv {
font-size: 12px;
font-family: Arial;
margin-right: 1em;
overflow: auto;
overflow-x: hidden; (optional)
-webkit-overflow-scrolling: touch; (enable smooth scrolling on mobile)
height: 0; (omit-able)
}
$(window).resize(function(){
$("#outputDiv").css("height",0).css("height",$(this).height());
});
$(window).trigger("resize");
TL;DR Full story
Page A.html - has an iframe to load Page B. When on Page A, that div#OutputDiv in that iframe must be scrollable. Works fine on PC but not scrollable on iPad/Android. Page structure:
Page B.php - Left half div#OutputDiv, right half div#map-canvas containing Google Maps.
(Sidenote: I think the #map-canvas CSS is pretty unchangeable, for example changing something may cause the Maps to extend height beyond browser height, which is not what I want.)

I can't see any overflow controls specified in the CSS (apologies if I missed them).
Have you tried:
div#OutputDiv { overflow: auto; height: 200px; }
The height is just for testing purposes - but you could use Javascript to get the actual height and apply it using either raw javascript or jQuery.
A good example (including how to detect orientation changes if device goes portrait to landscape or similar) can be found on:
How do I get the new dimensions of an element *after* it resizes due to a screen orientation change?
I have done some absolute positioning with css. But in the following case, why in the firstBox , the top and left values are ignored? (I want top at 100 px and left at 100px). The Second box is pisitioned correctly.
<html>
<head>
<title>Testing</title>
<style type="text/css">
#firstBox {
color: white;
width: 500px;
padding: 1em;
background: red;
position::absolute;
top:100px;
left:100px;
z-index:2;
}
#secondBox {
color: white;
width: 500px;
padding: 1em;
background: blue;
position: absolute;
top: 100px;
left: 100px;
z-index: 0;
}
</style>
</head>
<body>
<div id="firstBox"> The First Box! </div>
<div id="secondBox"> The Second Box! </div>
</body>
</html>
It is because you are using 2 colons for position: absolute; for #firstBox
My Fiddle
I am working on an app for a client and am trying to create a button with a completely custom icon. The icon is 30px x 30px and transparent in the middle.
I have almost achieved what I want using this css code:
/* info button override */
.ui-icon-info-page {
background: url(images/G_help_icon_round.png) 50% 50% no-repeat;
background-size: 30px 30px;
background-color: black;
}
But there is a thin black circle that appears inside the icon, and also the icon image appears to be cut off:
I want to remove this circle and prevent the icon ? from being cut off. Also, I would like the question mark to be transparent instead of black, to show the image of the navigation bar beneath. If I try to set the background color to transparent though, the button appears entirely white:
How can I do this?
Update:
I tried applying this code:
/* info button override */
.ui-icon-info-page {
background: url(help.png) 50% 50% no-repeat;
background-size: 30px 30px;
width: 30px;
height: 30px;
margin-top: -15px !important;
box-shadow: none;
-webkit-box-shadow: none;
}
And got this result:
I'm able to move the icon around by adjusting the top and left margins, but it's edges are cut off outside a frame centered on the black circle:
Update 2:
Here is the button I am using (Note that it is invisible here because it is a white button on a white background):
Here is the html code that I use to load the button:
<div data-role="header" data-position="fixed">
<div><img border="0" src="images/G_iphone_navbar_logo.png" style="display:inline;"/> </div>
</div>
This should fix the issue
/* info button override */
.ui-icon-info-page {
background: url(help.png) 50% 50% no-repeat;
background-size: 30px 30px;
width: 30px;
height: 30px;
margin-top: -15px !important;
box-shadow: none;
-webkit-box-shadow: none;
}
Please ensure you are loading your application css file after jquery mobile css.
