I have some code which looks like this:
<iframe src="https://adamwilliams.eu/iframe.html" style="height: 100px; width: 300px; border: none;"></iframe>
Note that the iframe includes a position: fixed element at the bottom of the page. It is important that the iframe does not exceed 100px in height.
This works on almost every platform, except for mobile Safari where the iframe height is just ignored and it overflows into the parent.
Most StackOverflow posts that deal with mobile Safari and iFrames suggest placing it inside a fixed height overflow: auto; -webkit-overflow-scrolling: touch; element. As you can see from the screenshot below, this does not work properly because the fixed element is "no longer" fixed and is only visible when scrolling down to the very bottom:
I've tried resizing the iframe with JS to no avail. Is there anything else I can do to get this to work?

i have an phonegap app running on ios. (Tested on ios 10) In one of the views there is an iframe from an external source. the iframe loads fine, but the touch events inside the iframe are erratic. when i scroll down to the bottom of the iframe, there is a submit button on the form inside the iframe. when i try to tap on it, the tap is registered at near the top of the frame (the initial position of the iframe view before scrolling down the iframe). i found some articles regarding scrolling of iframe on iOS and added a div around the iframe and put the following css on it:
#wrap-iframe {
position: fixed;
top: 75px;
right:0;
bottom:0;
left: 0;
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
}
but it did not solve the problem. any ideas/pointers would be highly appreciated.
I have a div styled to truncate centered text with an ellipsis, with some padding on each side. It works when using a desktop browser, but on iPad the text seems to ignore the right padding and becomes centered incorrectly.
I'm using this for the styling:
div {
text-overflow: ellipsis;
width: 120px;
padding: 0 38px;
overflow: hidden;
white-space: nowrap;
border: 1px solid black;
text-align: center;
}
An example can be seen here. View on iPad to see the problem. http://jsfiddle.net/35Lyk9yp/
I'm thinking this might be some bug with the mobile browsers? It didn't work on iOS Safari or Chrome, but it's ok on Windows Safari and Chrome and Firefox. Is there a simple workaround for it?
Edit:
I found a workaround by using an inner div with the content that I used to do the ellipsis, and then used the outer div to set the padding. If there is a way around it with one element though, please let me know.
In order to get your code to work you need to have CSS overflow, width and display.
You are probably missing the display.
I'm trying to get momentum scrolling to work, by setting a class called momentum-scrolling on a top level div that wraps the part of the content that scrolls. The class is defined as:
.momentum-scrolling
{
overflow: auto;
-webkit-overflow-scrolling: touch;
}
Yet it is not working (testing in simulator on both iOS 7.1 and 8.1).
Here is a link to view the example on jsbin directly (suitable for viewing in a mobile device for testing):
http://jsbin.com/cewobokisi/1/
Here's the link to the editable stuff on jsbin:
http://jsbin.com/cewobokisi/1/edit?html,css,output
(Note that the CSS shown includes minified bootstrap, and a few other things. I left this like this because while it's a bit harder to edit, I was trying to reproduce the issue exactly as we have it in our site now, in case anything we're doing is causing the issue.)
Update
I've got a modified version here (http://jsbin.com/sibofucexe/1) where I've modified the .momentum-scrolling style to include position: fixed, height/width 100% (based on some other posts I found with momentum scrolling examples):
.momentum-scrolling
{
position: fixed;
height: 100%;
width: 100%;
overflow: auto;
-webkit-overflow-scrolling: touch;
}
And that does now allow for inertial/momentum scrolling to work!
However, now I lose the ability to tap on the top bar to scroll the window to the top, and occasionally I cannot scroll up or down (typically when the DOM is being manipulated by JavaScript, due to an ajax hit to add more data).
Any ideas on these issues? Am I doing this wrong?
I know this is a late reply, but for the sake of future Googlers:
According to CSS Tricks, you must use overflow: scroll rather than overflow: auto. That may cause your first example to work.

I have a MacBook Air, an iPhone 5 and an iPad Air so I phrase this for iOS 8.1.1 but obviously I want the solution to work for all tablets and smart phones across all platforms.
On the "Class Schedule" page of the site I have an iframe that works correctly on my MacBookAir running OS X Yosemite (10.1.1) but on my iPad Air and iPhone 5 running iOS 8.1.1 the frame width displays improperly. It extends to the right beyond the right edge of the page. If you visit the site on a a desktop or laptop then on a mobile device you should see what I mean.
My question is: what code do I use to get the iframe to display properly on mobile devices?
The relevant code is:
<div style="text-align: center">
<iframe src="url"; frame-border="1"; height="600px"; width="100%">
</iframe>
</div>
As I said, this code works correctly on the MacBook Air. The iframe occupies the width of the page. But on the iPhone and iPad the frame extends beyond the right border of the page. What am I doing wrong? (By the way, if I set the height to 100% I inexplicably get a frame about 200 px high although the source document takes 600px to view all of it.)
I've consulted two texts on HTML coding, searched other forum sites on the web and searched this site for the answer to similar questions but have had no luck. I've seen the item "Iframe on mobile devices problematic" on this site but I'm really hoping that I'm not stuck with that for an answer.
Any help will be greatly appreciated.
Thanks

The best responsive iframe code I've come up with thus far is:
// HTML:
<div class="iframe-container iframe-container-for-wxh-500x350"
style="-webkit-overflow-scrolling: touch; overflow: auto;">
<iframe src="http://urlToTargetSite.com">
<p style="font-size: 110%;"><em><strong>IFRAME:</strong> There is
iframe content here but your browser version does not support
iframes.</em> Please update your browser to its current version
and try again.</p>
</iframe>
</div>
// CSS:
.iframe-container {
position: relative;
margin: 5px;
height: 0;
overflow: hidden;
}
.iframe-container iframe {
position: absolute;
top: 0;
left: 0;
margin: 0;
padding: 0;
width: 100%;
height: 100%;
border: 1px solid #7a8b8b;
/* put following styles (necessary for overflow and
scrolling handling) in div container around iframe
because not stable in CSS
-webkit-overflow-scrolling: touch;
overflow: auto; */
}
.iframe-container-for-wxh-500x350 {
padding: 10px 10px 70% 10px; /* padding-bottom = h/w as a % */
}
The rationale behind the code can be seen at How To Make Responsive Iframes -- It's Easy!
There are three salient points:
Set no attributes in the iframe opening tag, specifically not width and height.
Put a div container around the iframe, and use CSS height: 0; and then padding-bottom: nn%; to give the container a height equal to the height:width ratio expressed as a percentage.
Style the div inline with -webkit-overflow-scrolling: touch; and overflow: auto; which are necessary to handle scrolling and overflow on mobile devices and are unstable in CSS.
There's an iframe, which basically has more content than fits into the frame. The sizing of the frame is based on the browser screen size and lets the overflow scroll, which works perfectly on all browsers, except for iOS. On iOS, safari decides to resize the frame to fit the content. Not what you'd expect.
Example code on jsFiddle:
http://jsfiddle.net/R3PKB/2/
Try it out on your iOS devices:
http://jsfiddle.net/R3PKB/2/embedded/result
The HTML:
<div class="frame_holder">
<iframe class="my_frame">
// The content
</iframe>
</div>
The CSS:
body {
position: relative;
background: #f0f0f0;
}
.frame_holder {
position: absolute;
top: 50px;
bottom: 50px;
left: 50px;
right: 50px;
background: #ffffff;
}
.my_frame {
width: 100%;
height: 100%;
border: 1px solid #e0e0e0;
}
You can make it work by adding a wrapping div with overflow: auto; and -webkit-overflow-scrolling:touch;.
Here's your example with it: http://jsfiddle.net/R3PKB/7/
According to previous questions on SO it's a bug since iOS 4. I found more info here:
https://stackoverflow.com/a/6721310/1047398
iframe on iOS (iPad) content cropping issue
This is an old question, but since it comes first on google and the issue exists on nowadays ios devices, I repost a better fix that I found on this page:
How to get an IFrame to be responsive in iOS Safari?
Basically, if you have an iframe with scroll (let's say a twitter widget), the solution above won't work very well because it makes the parent scrollable. The fix that worked for me is replacing height: 100% with height: 1px; min-height: 100%;.
If iOS Safari is displaying your iframe content from a different origin than expected (i.e. it is shifted over by some pixels), try adding scrolling="no" as an attribute to the iframe. This should prevent it from automatically fitting its content.
More here.
using height: 1px; min-height: 100%; did not work for me, though I did not need a scrolling element. I had to use the overflow:auto; on a surrounding div instead. Note that this method is discouraged as it may have unintended consequences, but I tested on Android/iOS and desktop browsers and could not find any issues yet. fingers crossed.
