First off, after doing some research I am aware of previous issues relating to input fields causing issues on iOS. However, apparently this was fixed in iOS update 11.3. The device I am using for testing is an iPhone 5s running iOS 11.4.1.
I have created an html document (includes css and JS) and it is stored on the Google Cloud Platform here. If you open this link on either an Android or iPhone, everything displays and works as intended.
I am using AppPresser to create a mobile app. A page of the app loads the Google Cloud link and displays it with no issues. AppPresser provides a previewer app that can be installed on a device for testing the current app build. On an Android device, the html page still works perfectly as intended, but there are issues when testing on an iPhone. Here are some screenshots:
If the "Purchasing Price" input is focussed while at the bottom of the screen, it moves to the top as space is made for the keyboard.

After:
However, if the "Purchasing Price" input field is near the top of the screen and it is focused, everything seems to go haywire. The container vanishes and a previous container is shown. The user cannot see what data they are entering.

After:
I find this issue to be very strange, especially as the html page works perfectly on an iPhone when opened directly through the browser. Any feedback would be much appreciated.
Thanks
I thought I had tried all the fixes provided online, but adding the following css:
html,body{
-webkit-overflow-scrolling : touch !important;
overflow: auto !important;
height: 100% !important;
}
from this article, did the trick! I am still confused by two things that maybe someone can clear up for me.
Why did this issue only happen when previewing my app build, and not when loading the html file directly through the iPhone's browser (file is hosted on the Google Cloud Platform).
Why did I have to implement a fix for this, when apparently the input issues were addressed in iOS update 11.3

I'm using Font Awesome 5 Free via a kit. On desktop, the icons work perfectly. But on mobile (iOS chrome (normal and incognito), iOS firefox focus, iOS safari), they behave like Schrödinger's cats...
On first page load, the icons appear. Tap reload and they disappear and are replaced by small squares. Tap reload again and they reappear. Every other tap of reload shows or hides the icons.
I notice the same behavior if I toggle back and forth between "request desktop site" and "request mobile site". (I'm not sure what's really going on under the hood there since the page renders the same either way.)
Since they do appear correctly, at least part of the time, I don't think it's a cross-origin problem or a caching problem.
An example page is here: https://onlinesafetyzone.com/learn/learning-zone.php
I've read many posts, here and on GitHub and none of the solutions has worked. Anyone have a clue what's going on?
It seems you have somekind of a XSS issue. I would try to download the fontawsome resources and deploy them with the application. Can be that they have a CDN problem, every second time the fonts break :| so maybe one of the nodes is flipping.
My code is open source and that particular branch is currently deployed so you can see what is happening if you have an iPhone.
I've captured what is happening to show the problem.
This is only a problem on iOS, I am testing this with my iPhone SE, but I imagine newer iPhones will have the same issue.
On Android, this problem does not exist. It looks fine on Android!
The search input should be at the top, ready to receive input from the user.
How can I make it behave the same on iOS? I have already tried:
Giving position: fixed to the body.
I already tried window.scrollTo(0, 0); here.
UPDATE
I've created a little HTML/CSS file as a playgournd specifically for finding a fix. It is deployed here.
I'm not an expert in web and I composed and updated my website recently. I ran all the test that I could on DreamWeaver CC and tested on multiple mobile devices (tablet, android and iphone); all seems to work fine. Until I uploaded the site to my server, the site start to act weird.
1st problem:
It is a portfolio website with individual pages to corresponding projects. On each project page, the first image on the lightbox has always gone missing; but clicking into the lightbox I can find the missing image (the preview image and the lightbox image share the same source so if the lightbox can find the image it implies that the image is on the server and the path is correct).
2nd problem:
when the browser is shrink below certain size, a toggle menu will replace the content on the header, clicking the toggle menu will show a pop up menu to site links. For some reason, after uploading the site to server, the toggle menu pop up never work.
3rd problem:
The above problem is never apparent on desktop browser(all image shows up correctly; toggle menu works). To make the problem more complicated, I can't confirm if it is device or browser oriented problem. For example, the site works on chrome browser on my iphone and nexus 5(android), but problem occurs on my xperia tablet(android) chrome browser; on my xperia tablet, the site works perfectly on firefox.
Does anybody has any idea what the potential cause to the problem, and perhaps a direction to a solution?

Thank you for your time and look forward to any reply.
Looks fine to me (Google Chrome), you need to use media queries for some certain resolutions. You also need to use some cross browser css tags lide "-webkit, -moz, -o" etc.
I'm currently working on one of my first two projects and you can tell that I'm still at the beginning of my youtube-tutorials-&-SO-powered learning journey:
our neighbor's skin & beauty spa
Please don't be too harsh on my code :D I've hand-written everything from scratch in a little editor.
In short, everything seems to work A-OK on desktop computers (I tested FF and Chrome), but on the iPad and other tablets I'm experiencing nasty bugs - I'm having major trouble with two issues:
the Google Maps iframe is always visible (overlaps other
sections) on tablets even if the corresponding section isn't clicked
on in the menu, and I have no idea why! It seems that the
visibility:hidden on a position-fixed element isn't interpreted
correctly?
:focus works on the image gallery 'sneak peak', but
in the services section, the 4 sub-content areas are inaccessible.
(Unrelated?) When the page loads on my iPad (mini) the #logo_box
div appears at page load, but turns semi-transparent the very
instant as the map iframe appears.
EFFORT1: I removed the Google maps iframe-containing 'content' container altogether, and suddenly the :hover on the other content sections stopped working as well. This might be an indicator that something is 'linked' in a way that's not right...
EFFORT2: I assumed that the < label> is the culprit, but I can't pinpoint it. I tried this suggested solution, but it's for IOS4 (2011), and as Rob Fletcher commented last Feb., it doesn't work on IOS7.
EFFORT3: I feel that the .content div's {visibility:hidden/visible;} is causing trouble in the android mobile browser: input:checked hides instead of reveals the particular section while all others show.
Btw, how do I friggin' trouble-shoot tablets? I don't have any dev tool on ipad & android browsers.
Help is much appreciated!!
On iPad, you can go into the Settings App, then go Safari -> Advanced -> Web Inspector.
Then plug it into your Mac via USB and open Desktop Safari on the Mac. If you haven't already enabled the Develop menu, go Safari -> Preferences -> Advanced -> Show Develop Menu.
Then when you open a web page in Safari on the iPad, you can connect to it via the Develop menu on your Mac's Safari and use the web inspector.
If you're using Chrome on Android you can use remote debugging https://developer.chrome.com/devtools/docs/remote-debugging
Weinre provides similar functionality across more platforms (including Android native browser), but is a bit more involved to set up.
I'm developing a PhoneGap application. In iOS 5.1.1 there was no problem but in 6.1.3 there is a scrolling issue.
If I use a container with overflow:auto; -webkit-overflow-scrolling:touch; and the content is larger than 4000-5000 px, Safari crashes after scrolling.
You can test it with the link below. Click the map and scroll it after zooming in 4-5 times.

I know the problem is not SVG or too many DOM elements. Is there a bug in iOS 6.x? How can I see the crash report of Safari? I'm using Windows and these isn't CrashReporter under \Users\<username>\AppData\Roaming\Apple Computer\Logs\
Thanks in advance.
Maybe an iOS issue. Did you test on iOS 7 (for having an idea) ? On Mac, using Xcode Phonegap project and the debugger, you might have more informations. Maybe the problem comes when you load in one time all the content.
If you paginate ? Four by four with a button in the bottom to load others. It's not cool for your interface but if it's an iOS issue, you may not have the choice...
