I'm trying to get my website to fit inside my phone screen. I have tried many variations of env(safe-area-inset-bottom) and constant(safe-area-inset-bottom) but both always return 0px (I've been using an app called Inspect to debug CSS on my iPhone 13).
Here's a link to the github repo. All code that relates to this issue should be in /src/app.tsx. Here is a link to the live site if you want to see the problem yourself.
UPDATE: I've been doing some testing and have found that in portrait mode, safe-area-inset-* is ALWAYS 0px, but in landscape mode it works as expected. Does this mean that safe-area-inset-* isn't the correct solution for ios 15 safari? Clearly the url bar obscures the 'safe area' in portrait mode...
I've made sure to add <meta name="viewport" content="width=device-width, initial-scale=1.0, viewport-fit=cover" /> to my head tag but this has no effect. Could someone please explain how I can ensure that my site doesn't go past the bottom URL bar on ios 15 Safari? I've attached screenshots from my phone showing the problem:
I think I made it work using -webkit-fill-available the other day which respects safe area.
body {
min-height: -webkit-fill-available;
}
On iPhone IOS 13 and iPadOS, Safari has tappable "AA"on the left of the web address bar.
Tapping it allows the user to enlarge or decrease the text and other element size.
If we decided our website actually looked better at 115% on iPhones and iPads after playing with that AA feature, what would we need to do to our existing CSS and HTML?
We tried the unsupported CSS:
zoom:115%;
on body, HTML and (body, html) but it didn't do anything until it was 120%, and even then the font sizes stayed the same.
What exactly does the iOS AA functionality do technically so we can mimic it? I did ask someone on Medium if that feature was programatically accessable but he said no.
UPDATE 1:
Based on the first comment below, I used:
<meta name="viewport" content="initial-scale=1.15, user-scalable=no, maximum-scale=1.15, viewport-fit=cover" />
and it worked on iOS iPad Safari. I did have to remove:
width=device-width
from that Meta though so the page wasn't too wide. Otherwise a horizontal scroll bar appeared and some content was over the page to the right.
Firefox Windows desktop had no effect for some reason.
And also when I rotated the iPad into Portrait view, the page items actually appeared smaller than when the initial-scale and max-scale was originally set to 1. Maybe 15% smaller. When I rotated it back to landscape the items were 1.15% larger than the orginal (e.g. the Meta tag above seemed to work for that).
FWIW: I think this has something to do with window.devicePixelRatio, at least this is what value changes on desktop browsers (by entering the above in the console) when you use the browsers zoom in/out functionality.
Not sure how to set this value programatically though. Oddly enough, when using the Aa zoom feature on iOS and inspect via Safari > Develop > iPhone on a Mac, entering window.devicePixelRatio always seems to return 2.
This also may be worth looking into if it hasn't been setup correctly: https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
When setting the meta tags
apple-mobile-web-app-capable
and
apple-mobile-web-app-status-bar-style
to create a full screen web app, the iOS status bar is at the top of the screen (translucent) and there's an additional empty black bar at the bottom.
Here's my code:
<!DOCTYPE html><html><head><meta charset="utf-8">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta name="apple-touch-fullscreen" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
</head>
<body><h1>Test</h1>
<p>Capture a photo using camera</p>
<input type="file" capture="camera" accept="image/*">
</body></html>
There's an additional problem with the tag apple-mobile-web-app-status-bar-style. After taking and accepting a photo via camera input black bars appear on the sides of the screen.
I'm using iOS8 GM on an iPad3.
I think this might be an iOS 8 bug but Apple doesn't seem to care about my bug report :(
Does anyone know a solution/workaround for this problem?
Update 1:
Apple marked my bug report as Duplicate (Closed) on Sept. 19th.
Update 2:
Bug is fixed in iOS 8.3 Beta 1
Technically this is not an answer to your question, but I have been documenting my findings while trying to resolve this issue myself, and here is what I've found so far. I was going to post it as it's own question, but figured it would be closed as a duplicate.
On iOS8 devices running pinned web applications. Regarding the tag :
<meta name="apple-mobile-web-app-status-bar-style" content="black">
From the Apple developer reference:
If content is set to default, the status bar appears normal. If set to black, the status bar has a black background. If set to black-translucent, the status bar is black and translucent. If set to default or black, the web content is displayed below the status bar. If set to black-translucent, the web content is displayed on the entire screen, partially obscured by the status bar. The default value is default.
To enable this functionality, you need to use
<meta name="apple-mobile-web-app-capable" content="yes">
In iOS6 and 7 this works more or less as expected.
In iOS8 this appears to be broken entirely. For example, iOS 8.0.2 running on an iPad Air in portrait has the following behaviour:
black results in a transparent background. There is a solid black bar at the bottom of the screen
default or not setting a value results in a transparent background and a solid white bar at the bottom of the screen
black-translucent results in a transparent background, but no annoying bars at the bottom of the screen
In all cases, the content appears "beneath" the bar. i.e. the bar does not push content down.
On an iPhone6, the status bar does not display at all in landscape. In portrait however, the following behaviour:
black works as expected, and content is pushed down (wow!!!)
default has an empty white bar at the top
black-translucent results in a transparent background, with content underneath
I have not had the opportunity to test on an iPhone6+
The iOS simulator in xcode does not appear to give reliable reproduction of the behaviour that occurs on real devices.
I have tried changing it dynamically with javascript, but it appears to have no effect.
Just to make this even more interesting/frustrating, you can COVER the status bar (clock/wifi etc) by setting styles on the html element. e.g.
html {background: black;}
body {background: #DDD; margin-top: 20px}
The same issue documented elsewhere:
https://discussions.apple.com/thread/6557230?start=0&tstart=0
The problem existed since iOS6.
I had previously posted to Apple's bug report with all details you are providing today, and later was marked as duplicate. This was 2 years ago and unfortunately today I discovered that it got even worst.
The original bug report has id 11966202 and is still (Open).
Since you have the same problem the only thing you could do is confirm the bug which will escalate it and they will fix it in the future.
As I said I am looking for a solution for more that enough to tell you there is no workaround.
The problem can be reproduced on all iOS devices, but behaves differently based on the screen size and orientation.
With iOS 8 we now experience a glitch where the viewport becomes just a very small portion of the screen and it closes/crashes completely.
EDIT: Apple Ticket is now closed
As of Monday, Apple had closed the ticket and I can confirm that using 8.1 finally resolves the camera and status bar issues I was having. Hope it resolved your issues too :)
The issue comes from using <meta name="apple-mobile-web-app-status-bar-style" content="black">In order to get rid of the black bar at the bottom of your app, you will need to use:<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent"> Using black-translucent will keep your app looking the same in both iOS7 and iOS8. You will still need to adjust any content at the top of your app to clear the iOS status bar icons.
Apple fixed this bug in iOS 8.3 beta 1
To expand on all of the above, my solution is:
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />
Then create a custom CSS for all the elements that need to shift down by 20px, particularly any position: fixed; top: 0px; that exists in your CSS for normal browser [desktop/mobile] view.
Add the custom CSS into the head section, below CSS links with the following script [my working example]
<script type="text/javascript">
if (window.navigator.standalone) {
document.write("<link type=\"text\/css\" rel=\"stylesheet\" media=\"all\" href=\"assets/css/style-body-ios8.css\" charset=\"utf-8\" \/>");
}
</script>
My result is desktop/mobile browser website view is as normal, then website added to home screen as a web app, on launch opens fullscreen, with status bar looking like it used to pre ios8 [fyi, I added a background color of black to my fixed header css for the status bar to show as black background
Tested on iPad/iPhone/iPod running ios 8.0.2 - all good. FYI, tested on old iPod ios 6.1.6 expecting an extra shift down of 20px and wasn't there - bonus!
It is worth noting that setting the status bar style to 'black' is working as expected as long as you open the Web App with your iPad in Portrait. Then even if you rotate the iPad the black bar is correctly visible.
The problem is only when you enter the Web App in landscape, at least for me. I am using iPad 3 with IOS 8.1, and I believe it is still the same in 8.3
Just add a 20px high div to the top of your app and let that act as that status bar
apple-mobile-web-app-status-bar-style is inactive in iOS 8.
If you add a fixed div on top, only add it for OS 8_0
if (navigator.appVersion.indexOf("OS 8_0 like Mac") > 0) ...
I'm developing the mobile version of a web and the client requested me to allow zooming.
The problem is that in some browsers (like the iexplorer of windows phone or the browser of android) it makes a normal zoom without resizing the window, so the elements simply are viewed bigger, but in other browsers (Safari on ios or chrome on android) it makes a "responsive" zoom, resizing the window and adapting the elements to the new size, changing their positions.
The client has seen this inconsistency and he likes the first type of zoom, so he asked me if i could make this "non responsive" zoom working on all the devices.
I have been researching how to do it but i didn't find anything about the browsers making different zooms or how to avoid the second type of zooming. So if anyone could explain me anything about this i would be very grateful. Thanks.
Add this to your HTML inside the <head> tag:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
I am trying to fix some layout issues with browsers on tablets. And currently the browsers on surface and Android works okay, but there are some problems with Ipad.
This the main page displayed by an Android Tablet browser:
And this is the main page displayed by Ipad (safari and chrome)
The webpage is using bootstrap and the URL is http://hra.case.edu.
Here is my meta tag
<meta name="viewport" content="width=device-width,initial-scale=1">
Also I set a min-width=100% to the header div, but it seems to be useless in a certain page on iPad, please see this image:
Anyone has some ideas about those problems?
