I am writing an Angular (v.9) web application which contains few tiles on the scrolling panel. When given option is out of order I set blurred grey background with text on it. It works fine on desktop chrome/firefox/edge and mobile chrome/firefox. However when I test it on iOS with Safari text becomes too large for the tile. Even though I set font-size property on the "p" element itself:
<p style="font-size: 14px">
sometimes computed style says 21px.
As you can see, I marked that with red rectangles. Moreover, the issue does not appear on all tiles - as you can see blue one looks fine - font size is 14px. Unfortunately the presence of the issue on the particular tile seems to be totally random.
I use BrowserStack for testing, problem appears only on all iPhones (checked 8, 10, 11, 12) with Safari. Running Chrome does not produce issue.
It is not possible to expand "font-size" tree so I have no idea where that value come from, I haven't set 21px anywhere.
Do you have any ideas how can I force Safari to use given font-size? I've already tried multiple tricks like using !important, changing size based on some properties or even set different font size on click - works on all browsers but Safari.
Try this (only for iPhones)
#media screen and (max-device-width: 480px){
body{
-webkit-text-size-adjust: none;
}
}
and also make sure your code has the correct device meta tag
<meta name="viewport" content="width=device-width; initial-scale=1.0;" />
This is the mixin that I use for the Safari browsers
#mixin safari-only {
#supports (-webkit-marquee-repetition: infinite) and (object-fit: fill) {
#content;
}
}
You can use that in your .scss file as follows:
#include safari-only() {
// your CSS
}
I have an iOS web app. I have the following css applied
body{
background-color:red;
}
This red background shows up in iOS safari but when I save it to the home screen the background is white.
Why is this happening and how can I fix it?
I'm sorry but I wasn't sure whether you were talking about the home screen icon or the website background color.
1. If you mean that the icon is getting white you can fix this by a meta tag:
<link rel="apple-touch-icon" href="the/url/of/your/icon-image" />
2. If you mean that the background color is white instead of red, I would suggest that you just put it as inlin styling, like this:
<body style="background-color:red">
Or you can use the background property, so your css will be like this:
body {
background:red;
}
I hope this answered your question and that it will work!
On my iphone phonegap app, whenever I've got text on a background color, the text seems to get a ghosting effect, the same text is repeated 2 or 3 pixels below, almost like a drop shadow but exactly below and in the same color as the text.
Any ideas how to get rid of this? I'm guessing its applying some kind of -webkit specific styling but I can't seem to find what it is.
Below is an image of what is happening, the text to the left, 'Web Deal' is the problem, whereas the text on the right is fine.
Ok, I managed to fix this, it was picking up a text-shadow property from jquery mobile css. It was applying it to all text but because its white it was only visible on text with a background colour. Thanks for your help
Please post your css.
If you are able to open the app on Chrome browser on a desktop, try inspect element and you can find which styles are applied to the text.
As you didn't provide any CSS I'll just assume that your text ist rendered bold.
Rendering bold type in mobile Safari or the WebView is buggy and causes the weird effect.
Try using a text-shadow instead.
.bold {
//font-weight: bold;
text-shadow: 0 0 0 2px white;
}
I recently upgraded our mobile application to use JQM 1.1.1, and noticed a very big problem on Blackberry 6 browsers.
The screenshots tell the story best.
In the first image you'll see the search text box rendered correctly.
However in the second image you'll see that when the input text box is focused, it makes the textbox black
Please see my screenshots:
Has anyone seen this issue?
I had the same problem, and fixed it with css like this:
input.ui-focus, textarea.ui-focus {
outline: none;
-webkit-box-shadow: none;
}
Thank you for your answer.
From my side, I had to set css to:
.ui-btn.ui-focus, .ui-input-text.ui-focus, ui-input-search.ui-focus
Hope it will help!
In recently testing a web application on Windows/Mac desktop browsers - and then on an iPad I noticed various differences in Safari that I wasn't expecting. Even though the version # is the same.
I'd like to compose a list of those differences (for myself and others) to have as a developer reference.
e.g. in Safari on the iPad
iPad Safari takes full control of Select list/option styling
iPad opens the onscreen keyboard when an input element receives focus, thus inline floating calendar widgets (and the like) may not work as expected (or need to be altered)
iPad Safari doesn't support position:fixed like desktop Safari < iOS 5
iPad Safari (similar to iPhone/iPodTouch Safari) automatically hyperlinks 10 digit numbers to offer phone #/contact options
iPad Safari prompt('long message...','default'); shows only 1 line of the message (though it does provide scrolling of the message
I've heard from others that certain JavaScript doesn't work, etc. etc. but I have yet to fully test it thus I'd be grateful for any discoveries that you may have encountered.
A few more for you:
No Flash
Lousy iFrame support (so facebook like etc. needs a custom implementation for iPad)
Weird caching limitations
HTML textAreas doesn't get a scroll bar (you have to double-finger swipe - which of course, is amazingly intuitive)
In general. Treat it like a scaled up iPhone, not a scaled down Desktop.
I thought this might be useful: Apple's guide to preparing web content for the iPad
Just been caught out by the position:fixed issue my self
Safari on iPad has the same issue with button width/padding as on the iPhone
iPhone <button> padding unchangeable? describes this problem and a solution for removing padding on a button with text, but this does not help you if you want a button to be narrower than the padding itself (e.g. for a button that only has a small icon on it). To do that, I had to surround the button with an outer element with a defined width and overflow: hidden like so:
<span style="border: solid 1px blue; display: block; width: 16px; overflow: hidden">
<button style="-webkit-appearance: none; border-width: 0"> </button>
</span>
(the blue border is to show where the button is, it's not critical to the hack)
jQuery's offset() doesn't work: http://bugs.jquery.com/ticket/6446
It also looks like iPad Safari has issues with elements with overflow:auto; that therefore should show scrollbars (test page with div's and iframe's).
iPad Safari seems to have trouble handling background images in rare cases, showing weird lines of lower lying content.
There's not a lot about this in Google (yet).
iPad browser doesnt support file uploading(even if it supports it will useless as iPad does not have a standard File Browser). The file field appears with a Choose File button grayed out.
Beside doesn't support scrollbar in TextAea, it seems that we can using javascript to make text in TextArea selected automatically too.
This code will only move cursor to the end of text in TextArea.
<div>
<textarea id="text-embed-code" autocapitalize="off" multiline="">
There is a fox running after chrome.
</textarea>
<button onclick="testSelectText(event);">select text</button>
</div>
<script>
function testSelectText(e) {
var box = document.getElementById("text-embed-code");
box.select();
e.preventDefault();
return false;
}
</script>
There appears to be a bug in iPad Safari where a CSS element with both a background image and a background color is rendered with a slight border in the color of the background color. It should fill with the background image all the way to the edge of the rendered element.
I just had the same bug on my site, when trying to view it on an Ipad. The HTML structure is like:
<div class="main"> <!-- background-color: white -->
<div class="left"></div> <!-- background-image: url(some_transparent_png) -->
<div class="content">...</div>
<div class="right"></div> <!-- background-image: url(some_transparent_png) -->
</div>
The left layer uses a background-image, whereas the main layer uses just a background-color. The Ipad view shows a slight border at the edge of the left and right layer.
When i add
-webkit-background-size: 100% 100%;
to the left and right layer, the border disappears.
You can now control the styling of select lists on iOS by resetting it with -webkit-appearance: none;
This rule fixes animation flickering in Safari on iOS devices:
body {-webkit-transform:translate3d(0,0,0);}
There appears to be a bug in iPad Safari where a CSS element with both a background image and a background color is rendered with a slight border in the color of the background color. It should fill with the background image all the way to the edge of the rendered element.
24 bit transparent PNGS ABOVE A CERTAIN FILE SIZE don't render on the iPad2.
I can however get 8 bit ones of the same dimensions to render.
I haven't found out what this maximum file size is in order to get them to render.
I'm currently working on a small responsive web-app which makes heavy use of the iframe youtube api. Apparently the ipad version of safari doesn't support a few html5 methods which I use heavily in this project.
One of them is window.postMessage, which is a way of interacting with scripts on other pages, for example the a script that is used "within" that iframe. Autoplaying videos also doesn't work.
Frame problems. iPad Safari will both hide scrollbars and expand frames to the size of their content.
Changing the frame tag to include scrolling="yes" and noresize="noresize" appears to do nothing.
Some sites look fine on everything, even a Dreamcast browser, but not on iPad. The issue can be fixed using tables and iframes instead of normal framesetting (cols and rows, etc).
I also discovered that contenteditable is not supported in mobile safari, thus using a plain textarea is a better bet. Apple Developer Docs
position: fixed;
Does not work in iOS 4 but does work on iOS 5.
