I have a div set to width: 100%. When I load it initially in the portrait view of the iphone the element width is picking up at 480px.
The odd thing about this is that when I console log the width at load I am getting 320px. Also, if I manually change the orientation to landscape and then back to portrait then the element is getting the correct sizing.
I have tried a handful of suggestions to the meta viewport tag, but nothing seems to be working. Here is the current tag info:
<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1.0, maximum-scale=1, minimal-ui">
Also, when I change the zoom after initial load, then the element gets the correct sizing.
Any suggestions on how I can get the right size at initial load?
I was going to delete this post, but since someone upvoted it I figured I would provide the answer. The issue was that this element had position: fixed. I simply added position: absolute for the media query on mobile and it is now functioning properly. :)

I have one issue regarding ipad design i use one slider in to that when i turns mode portrate to landscape then it is not taking width of landscape
It takes width of Portrate mode and we have to reload the site to see perfect in to landscape mode i don`t want to reload site can anyone help me out form this issue
Use proper meta tags in your header. Try this.
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
I'm optimizing a web-app to work on the iPad Portrait mode. The web-app is built as an iFrame with a width of 350px.
I use the following meta viewport tag:
<meta name="viewport" content="initial-scale=1.0, user-scalable=no, width=350" />
I expect this to behave as follows:
- The width of my visible viewport will be 350px.
- My web application is initially scaled at it's original size, which means the 350px iFrame will be fully rendered in the 350px viewport(with no white space at the borders of the visible viewport.
However, the iPad Portrait mode seems to ignore the width=350 property and renders the page as width=device-width.
Can somebody explain why this is happening and how I have to interpret this behaviour?
In iOS, iframes ignore all viewport settings and render as device defaults. Very annoying.
See -
iOS Safari expands frameset larger than viewport
In our case the viewport size on iPad was equal to the content which is first rendered. So if you have your main container spread to the whole width of the page iPad says "the viewport of that iframed page is same as the devide-width". The solution in our case was to set strict size of the iframe by using the width, height and style attributes. Then simple apply overflow: hidden on the main container.
Here is a page I am working on for a class. Don't worry that it's all divs - the exercise allows that as it was to experiment with web fonts.
My problem is that the page renders fine in IE, Firefox, Safari, but on the iPad it doesn't center and the scale is off. If you look at the top left header "Top of the Napkin", it actually breaks into 2 lines on the iPad. There is no left margin yet quite a bit of right margin.
thanks for any help -
The above answer did not work for me on the iPad. Here is what did work.
In the body tag I added the minimum width of what I would want in a browser.
body { min-width:1080px; }
This worked without adding
<meta name="viewport" width=device-width />
but I left it in the header for good measure.
I checked the page on my iPad (latest IOS v5.1) and I can see the text "Top of the Napkin" on one line, though you are right about the entire page not getting center aligned..
For that, I would suggest you to do 2 things;
A. Set the viewport width as below (add this line inside your head element);
<meta name="viewport" width=device-width />
The above line would set your viewport width to device-width (i.e. 768px on the iPad). You can even hard code the value as
<meta name="viewport" width=900 />
Though this is not the best approach.
B. The other thing you can try is giving the following style to your body element
margin:0 auto
This would effectively center align your entire page.
There is some real good information on how to design websites for mobile (iPhone/iPad, etc) on http://bit.ly/rs1npZ
You probably need a viewport meta tag. Check the link for info on what this does and which to choose. http://www.allenpike.com/2010/choosing-a-viewport-for-ipad-sites/
I had the same problem.
for my part, the page was broken because of div elements bigger than their container.
i fixed it by playing with overflow-x property.
You may try putting overflow-x:hidden; on your containers.
I had the same problem. Here is how I fixed it:
<meta name="viewport" content="width=device-width, maximum-scale=.9" />
I am using CSS media queries to create a web site with responsive design. When I open my test page on the iPad in either landscape or in portrait orientation, it looks fine.
However, when I switch from landscape to portrait mode, the page is shifted to the left. I can tell that the correct CSS is loading because other things on the page change. I can also drag the page to the right and it appears exactly as it does if I had opened the page in portrait initially.
I have my viewport set to:
meta id="view" name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0"
I added JavaScript to fix the iOS viewport scaling bug which used to cause the page to be zoomed in when switching from portrait to landscape. (I used the solution described here: https://gist.github.com/901295 )
I'm having problems finding the name for the bug I'm experiencing when switching from landscape to portrait. Has anyone else seen this or know how to fix?
The problem owner says that she "can also drag the page to the right and it appears exactly as it does if I had opened the page in portrait initially."
This makes me think that, for some unknown reason (a bug?), the page is scrolled to the left at an orientation change to portrait mode (otherwise you wouldn't be able to drag it back).
I had a similar issue and solved it with the following JavaScript workaround:
// ...
// Optionally add a conditional here to check whether we are in Mobile Safari.
// ...
window.addEventListener('orientationchange', function() {
if (window.orientation == 0 || window.orientation == 180) {
// Reset scroll position if in portrait mode.
window.scrollTo(0, 0);
}
}, false);
Maybe this will work for others too.
I managed to sort my similar issue out - perhaps this will work for you?
You'll need to work out if it's a particular div or other element that's causing it by deleting/reinstating different bits and retesting the page. Once you've worked it out try adding an overflow: hidden property to that element in your CSS - I used overflow-x: hiddensince my issue was horizontal scrolling but you may need to vary it.
Hope this is of use... good luck!
Jereon, your JavaScript worked for me. My viewport is:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no" />
I'm using the Drupal Corporate Clean responsive theme. I have not had this problem using the Omega responsive theme framework.
The solution for this is as proposed by #ellawson
Problem is caused by some element not being scaled correctly by the browser when rotating the device. Find that element and apply overflow: hidden; or overflow-x: hidden; as he says.
Note: this question is a duplicate. I'll post the gist of my answer here.
2015 update
All the other answers are unfortunately incorrect, outdated, or misguided. Here's what works:
window.addEventListener('orientationchange', function () {
var originalBodyStyle = getComputedStyle(document.body).getPropertyValue('display');
document.body.style.display='none';
setTimeout(function () {
document.body.style.display = originalBodyStyle;
}, 10);
});
The code listens to the orientationchange event and forced a re-flow of the body element by hiding it and showing it 10 miliseconds later. It does not depend on any <meta> tags or media queries.
You said,
When I open my test page on the iPad in either landscape or in portrait orientation, it looks fine. However, when I switch from landscape to portrait mode, the page is shifted to the left
That is key. You just need to force a re-paint of the body.
Answers that suggest adding <meta name="viewport" content="width=device-width, initial-scale=1.0"> or variations thereof, as of Safari 7, no longer wors. Here's a demo. To make sure you see how it doesn't work, start with the iPad in landscape mode, load the page, then rotate. Notice the page doesn't expand to full height, despite using flexbox all the way.
Compare that to this page, where we use the hide/show body technique in production.
I came across this problem with an iPad and applied html { overflow-x:hidden; } . That seems to have resolved the issue.
try adding the following setting to your content properties: maximum-scale=1
or try this: user-scalable=no
here is the ios documentation
i have a mobile website for iphone and ipad where i disable user zooming with
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
this works fine as long as the site is in landscape mode. the width of the website is exactly the width of the screen.
then if i rotate the device into portrait mode it gets scaled down so that it fits the new (shorter) width. this is also ok.
but then if i rotate it back to landscape mode it is suddenly scaled to about 125% that means horizontal scrolling is now possible and zooming is not possible since initially disabled.
how can i make it back at 100% zoom when rotated back to landscape?
thanks!
try experimenting with maximum-scale and minimum-scale like so
<meta name="viewport" content="width=device-width, maximum-scale=1.0, minimum-scale=1.0" />
and see if you can achieve what you are looking for..
Disabling zoom is a bad idea. It's not a perfect solution, but targeting webkit's scaling of font size on orientation change can help minimize the problem. You would leave the head of the document with:
<meta name="viewport" content="width=device-width, initial-scale=1">
Then you would address the font-size scaling in your CSS like this:
body {
font-size: 1.5rem;
line-height: 2.3rem;
-webkit-text-size-adjust: 100%;
}
/* This prevents mobile Safari from freely adjusting font-size */**
Using the maximum-scale and minimum-scaleto stop zooming don't really work because then you take away the user's ability to zoom. That's really a bad idea because it makes your users with bad eyes angry that your website doesn't zoom, while other websites do...
I tried timeouts and all kinds of fancy javascript, then I found this:
https://github.com/scottjehl/iOS-Orientationchange-Fix
via this related question: How do I reset the scale/zoom of a web app on an orientation change on the iPhone?
On that post, Andrew Ashbacher posted a link to the code written by Scott Jehl:
/*! A fix for the iOS orientationchange zoom bug. Script by #scottjehl, rebound by #wilto.MIT License.*/(function(m){if(!(/iPhone|iPad|iPod/.test(navigator.platform)&&navigator.userAgent.indexOf("AppleWebKit")>-1)){return}var l=m.document;if(!l.querySelector){return}var n=l.querySelector("meta[name=viewport]"),a=n&&n.getAttribute("content"),k=a+",maximum-scale=1",d=a+",maximum-scale=10",g=true,j,i,h,c;if(!n){return}function f(){n.setAttribute("content",d);g=true}function b(){n.setAttribute("content",k);g=false}function e(o){c=o.accelerationIncludingGravity;j=Math.abs(c.x);i=Math.abs(c.y);h=Math.abs(c.z);if(!m.orientation&&(j>7||((h>6&&i<8||h<8&&i>6)&&j>5))){if(g){b()}}else{if(!g){f()}}}m.addEventListener("orientationchange",f,false);m.addEventListener("devicemotion",e,false)})(this);
That is a solution wrapped nicely in an IIFE so you don't have to worry about name-space issues.
Just drop it in to your script (not into document.ready() if you're using jQuery) and viola!
All it does is disable zoom on devicemotion events that indicate that orientationchange is imminent. It's the best solution I've seen because it actually works and doesn't disable zoom.
EDIT: this approach is not always reliable, especially when you are holding the ipad at an angle. also, i don't think this event is available to gen 1 ipads
