I have an iframe that I am embedding into a responsive WordPress theme. It looks good on some mobile devices, but on iPhone, the iframe is a bit wider than it should and it gets out of the container so users can't see the right part of the iframe (which is probably around 20-30px). This happens on portrait mode - if the orientation is set on landscape, it looks ok.
The content of the iframe is responsive as well, I'm using bootstrap. Also it looks ok on resized desktop browsers and on Android mobile devices. So the problem is only with the portrait iPhone orientation.
I am using this in the head of my iframe:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Any ideas?
Thank you!
Mobile Safari seems to not recognize width attributes on iframe, but recognizes min-width.
iframe{
width: 1px;
min-width: 100%;
}
The problem is that mobile Safari ignores the iframe width attribute. I created a new question here and answered it myself with the solution: How to set the width of an iframe in iOS6?
For the meta tag try starting with:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
If that doesn't solve it, look for what's causing the frame to be too wide, e.g. iframe dimension settings, width, padding or margins of elements inside the iframe, as well as margins or padding on the WordPress div that contains the iframe.
Remember that the iframe content is a completely seperate document so you need to double check details in both the parent WordPress page and the iframe page.
Good luck!

You could also check it's not a default browser setting by using a reset in your WordPress CSS, e.g.
iframe{
margin: 0;
padding: 0;
border: 0;
font-size: 100%;
font: inherit;
}

I'm working on a responsive email template for my employer. For the desktop size, I was able to leave the default font size at 16px and just use rem to adjust sizes as necessary. It looks fine on the desktop, in Gmail, and is fully responsive. However, when viewed in Mail on iPhone, the font is SO SMALL. I had to add a media query that increases the base font size to 26px to get reasonable font sizes in the email. I've tried doing some research, but it doesn't seem as if other people have had to do the same. There is very little CSS in the code, but here is what I have:
body, table, td, a, p, span {-webkit-text-size-adjust: 100%; -ms-text-size-adjust: 100%;}
#media screen and (max-width: 600px) {
html, td {
font-size: 26px !important;
line-height: 1.3;
}
}
I also have
<meta name="viewport" content="width=device-width, initial-scale=1">
There is some other CSS having to do with resizing images, with margins, etc. but that is the only CSS dealing with font-sizes (all the rem info is inline so it isn't stripped out by Bronto/Gmail). If I resize it in the browser to a mobile size, the text looks massive, but when viewed on my iPhone, it looks great. I'm concerned that this may be an iPhone quirk though and that it will look massive on other types of devices. Does anyone have any insight?
Here is some code from the templates I use (where I don't see this issue):
Try making your <meta> tags look more like this:
<meta name="x-apple-disable-message-reformatting">
<meta name="viewport" content="width=device-width">
The first tag disables auto-scale in iOS 10 Mail, which could be affecting your text size. The second tag sets the viewport; forcing initial-scale shouldn't be necessary and could be throwing off your design.
Also try moving the inline body styles from the <body> tag to inside a universal selector in <style>, like so:
<style>
/* What it does: Stops email clients resizing small text. */
* {
-ms-text-size-adjust: 100%;
-webkit-text-size-adjust: 100%;
}
</style>
<body width="100%" bgcolor="#ffffff" style="margin: 0; mso-line-height-rule: exactly;">
Have you heard of the viewport meta tag? You should consider adding this tag to the meta on your site. Just be cautious though as it could manipulate other HTML elements you have already configured.
<meta name="viewport" content="width=device-width, initial-scale=1">
Here is a link to a page explaining what it does in further detail.
https://developer.mozilla.org/en/docs/Mozilla/Mobile/Viewport_meta_tag
Okay, finally figured it out. Luckily I had been going through and making all our email templates responsive, and one of them didn't have a hero image. Guess what? The font size looked massive on mobile for the imageless-template! So after some experimentation, I found that
img {
width: 100% !important;
}
completely resolved the issue, so that now the actual font-size matches what is set in the CSS. Despite all the width:100% styles set on the image itself and on its parent containers, somehow the image must have been too large and triggered a resize of all content, I guess? If anyone has an explanation I'd love to hear it.
FWIW, I think you are complicating your life trying to use the text-size-adjust property.
According to the browser compatibility chart on this MDN document, there is poor browser support and it's buggy.
Secondly, the way I read this W3C doc I don't think you are using it for its intended purpose. W3C states that:
This module contains features of CSS relating to one possible
mechanism for adapting pages designed for desktop computer displays
for display on smaller screens such as those of mobile phones...
Its purpose is to provide a solution for pages which were designed for desktop display only.
As you know, older web pages which don't use the viewport meta tag will be scaled down to fit the viewport of a mobile device. The problem with this is that text often becomes too small to read and this text-size-adjust property proposes to remedy this by enlarging text on mobile devices.
I think if you continue to use the viewport meta tag, make your template responsive, and size elements so that they display well in all devices you would get good results if you don't use text-size-adjust, i.e. some like the following:
body, table, td, a, p, span {font-size:16px;}
Good sources of info about text-size-adjust:
https://developer.mozilla.org/en-US/docs/Web/CSS/text-size-adjust?v=control
https://drafts.csswg.org/css-size-adjust/#text-size-adjust
https://caniuse.com/#search=font-size-adjust
My problem is that I cannot get media query to work on iPhone 5s iOS 9.3.2 Safari. I have a full screen video on my page what I'd like to change into an image on mobile. I have followed this tutorial to make it happen.
I have specified the viewport like this:
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
I have included !important tag in every css entry I need to be changed when being 640px, like this:
#media only screen and (max-device-width: 640px) {
html {
background: url('image.jpg') no-repeat center center fixed !important;
background-color: rgba(0, 0, 0, 0) !important;
}
#video {
display: none !important;
}
body{
background: rgba(0, 0, 0, 0) !important;
/*also tried with background:transparent !important*/
}
}
I decided to use 640px as it is the exact amount of pixels what gets rendered on iPhone 5s according to this source.
I have specified that the background should be transparent as it seems to be the only option to work around the default template style. Meaning when background becomes transparent the background image shows up.
I have read this and this. I have applied the suggested solutions to my problem but none of them worked.
NOTE: I don't have the Mac machine to test this issue via iPhone's web inspector. Making a VM on Windows seems to be not a one hour job.
I have tested my code in Chrome 50.0.2661.102 m (64-bit), Mozilla 46.0.1 and Edge on Windows Phone everything works fine.
I have tried to work with Safari 5.1.7 (the last version released for Windows), but it seems to be very outdated (as expected).
I have also cleared the cache with Ctrl+Shift+R and tried to use Incognito mode.
UPDATE: if I specify the color (for the sake of testing) before the image I will be then able to see the specified color in Safari, but no image:
background: green url('image.jpg') no-repeat center center fixed !important;
Any idea how to solve this?
While waiting for help I've found a workaround just for my case. Thanks to #daemeron's answer.
So instead of implementing separate styleheets for different devices it is just possible to hide the annoying Play button on the background by:
*::-webkit-media-controls-start-playback-button {
display: none!important;
-webkit-appearance: none
}
This works great on iPhone and Windows 10 mobile. Exactly what I was looking for.
I'm making a responsive website.
It is a wordpress website with a modified theme.
The theme has 5 stylesheets: max-479 px, max-767px,min-768px,min1024px
I already tested the website on the ipad and on the Nexus One(Android). And it works great!
However when i test it on an iphone 4S it causes a css bug on mobile safari and google chrome.
The css bug is that when viewing the site the user can still swipe sideways, even though i used the folowing css:
html
{
width:100%;
padding:0;
margin:0;
position:relative;
overflow-x:hidden!important;
}
body
{
padding:0;
margin:0;
max-width:100%;
position:relative;
overflow-x:hidden!important;
}
And i inserted this meta tag in the header.php
<meta name="viewport" content="width=device-width,maximum-scale=1.0">
I checked if divs inside the content were overflowing in any way. But they weren't.
I am totally clueless what is left to do so it doesn't shift when the user swipes horizontally.

I appreciate you're help.
-- EDIT
Fixed the problem thanks to #ChrisHerbert and #mrbubbles.
It seemed that the sidebar had an ul that has a width of 120%, setting it to 100% solved the problem!

Just a guess - have you tried using the full meta?
<meta http-equiv="Content-type" name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no, width=device-width">
I have a fairly strange issue that I'm experiencing with jquery mobile / phonegap and IOS.
I've created a web app with html / css and so far it works exactly as expected on android, (The content scrolls vertically in the viewport) however on ios (my test platform is an iphone 4s), the page is limited vertically to the viewport. It scrolls just fine, but all content that sits below the viewport vertically get's cut off, IE the only content that will display is what I see in the upper half of the page, nothing below the viewport will display.
an excerpt from my css file:
html, body {
min-height:100%;
overflow-x:hidden;
background-attachment:fixed;
}
body {
-webkit-touch-callout: none;
-webkit-text-size-adjust: none;
-webkit-user-select: none;
-webkit-font-smoothing: antialiased;
-webkit-backface-visibility: hidden;
-webkit-overflow-scrolling: touch;
}
and my html page, in the head section:
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="width=device-width; initial-scale=1; maximum-scale=1 minimum-scale=1; user-scalable=no" />
Here's a couple screenshots of the problem in action:
As you can see from the screen shots, the gradient "should" fill the whole page (ie, expand with content), and it doesn't as there seems to be a hard cutoff at the viewport edge, so any more than a single page of content is not getting displayed. While it's not visible in these screenshots the vertical scrollbars are appearing as they should and the scrolling works fine, just no content is displayed "below the fold".
I am not using iScroll or any other scrolling scripts, just fyi.
I'm not sure if this is some sort of height issue, as I have a min-height:100%; set on the html and body of the page, or if it's some sort of width-device-width issue in the meta tag? I also do not believe I have any overflow-y:hidden set, as that would have limited the content on other platforms, and they work perfectly.
I feel like I must be missing something really basic, as I'm sure it's got to be some sort of css setting somewhere that's limiting the content to the viewport only, and an exhaustive google search could find no similar issues.
Check if your apps default orientation is set to portrait instead of landscape, or if it even supports the portrait orientation. It almost looks like its displaying the app as if its in landscape mode while its clearly in portrait. You can find the available orientation in the Target>General tab, or in the info.plist.
So I've fixed it, and the weird thing is, I'm not exactly sure what I did to fix the issue.
I moved the .ui-page selector from the jquery-mobile file to my own css file, removed the min-height from the html selector and killed the overflow-x from the html, body selectors and boom, it now appears to be working as intended. Wacky... but hey, a win is a win. :)
I have used a fixed footer in one my HTML5 web-app. It works fine on IE10 phone browser, but when I try it out on WP8 Emulator using web-view
mainBrowser.Navigate(new URi("http://jqtouch.rediffmailpro.com/iScroll/win8Example1.html",URiKind.Absolute));
It leaves a gap at the bottom.
I read it somewhere, and edited the meta tag to include the height.
<meta name="viewport" content="width=device-width, height=541 initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0">
The gap is gone. But, I don't think this will a good idea because on orientation change the footer is lost, as height remains 541. I don't want to hard-code the height anywhere, since multiple devices might have different height.
It seems the view-port height is not correctly set for css. I am using bottom:0; position:absolute; to fix the footer. I have tried position:fixed too.
Here is the reference link: WP8 Scroll Demo
Please help.
Use iscroll4 and use few media queries in css:
#media screen and (orientation: portrait) {
#-ms-viewport {
width: 320px;
user-zoom: fixed;
max-zoom: 1;
min-zoom: 1;
}
}
#media screen and (orientation: landscape) {
#-ms-viewport {
width: 480px;
user-zoom: fixed;
max-zoom: 1;
min-zoom: 1;
}
}
This works fine on Windows Mobile 8 Phones. Here is a demo: http://jqtouch.rediffmailpro.com/iScroll/win8Example.html
