iPad Overlay does not completely cover screen - iphone

I use a modal div as overlay to kind of disable the background page while the overlay DIV is open. Here is the code;
#TB_overlay {
height: 100%;
left: 0;
position: fixed;
top: 0;
width: 100%;
z-index: 100;
}
Now this works fine on desktop browsers, but on the iPad, the overlay window only covers upto the screen height and not the entire page. How do I fix this issue?
I know there are some known position:fixed issues and also giving a fixed px height value can fix this issue?
But please let me know if there is any other workaround for this issue.

I solved this on my site by using jQuery to calculate the size of the whole page and then setting the overlay height accordingly.

Conveniently enough the iPad supports:
<link rel=”stylesheet” media=”all and (orientation:portrait)” href=”css/portrait.css”>
and/or
<link rel=”stylesheet” media=”all and (orientation:landscape)” href=”css/landscape.css”>
I recommend using min-width / min-height in your ipad.css file.

Header Stretch: (1) will not shrink to fit iphone (2) how to set max width for desktop?

I am working on a CSS tumblr theme header found here grandneue.tumblr.com.
(1) Stretch: I want it to be able to stretch but only up to a maximum size as the header gets too pixelated otherwise), probably around 800px.
(2) Shrink: The second issue I have is, while the header does shrink down to a certain size (it does when I change the desktop browser window and to a certain extent on the iphone5), it doesn't shrink down fully so it fits 100% on a vertical iphone5 browser display.
Can anyone please help me solve these two queries? The content is totally fine so I don't understand why the header won't follow suit!
Looks like the problem is with the image, there's a lot of white space around the logo. Edit the header image to be 800px width and make sure the logo fits right to the edges. Then set the background properties on .header-image.cover to;
.header-image.cover{
-webkit-background-size: 100%;
-moz-background-size: 100%;
background-size: 100%;
margin: 0 -1px;
}
Then finally make the container div .header-image-wrapper ;
.header-image-wrapper{
max-width: 800px;
}
If on mobile the image is right to the edges, just add padding to the container with a media query :)
Hope this helps!

Two CSS Problems - One only happens on mobile, one on chrome

[link removed] on iPhone, the top banner will not stretch all the way. Solution?
heres a screenshot: ![enter image description here][1]
Here's the CSS ive applied to the div:
#banner {
background-color: #F7F7F7;
background-size: cover;
box-shadow: 0 0 30px 2px #DCCFBF inset;
display: inline-block;
height: 200px;
width: 100%;
Issue 2. In chrome, when I resize the browser window, the bottom two nav icons shift (graphic design and social media). I put them in a container to try to keep them in place but it still happens... only on chrome. I realize the whole site shifts, but the other icons in the nav stop after a while and the bottoms one overlap them and it looks bad. Any suggestions?
The banner doesn't stretch all the way because your content is wider than what mobile Safari treats as the full width. It then scales down the whole page to fit the content and strands the header a bit.
see this answer to a similar question
It is usually fixed by adding
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
to the <head>
As for the icons, Chrome seems to be respecting the #media query value of width: 100% on #home (line 528 of main.css) as you shrink the browser window while Firefox does not, and retains the first value width: 1020px (l. 91)

Responsive website on iPhone - unwanted white space on rotate from landscape to portrait

I am creating a responsive website, and have just noticed a strange behaviour in my content pages when viewed on the iPhone. It scales correctly when loaded in portrait mode, and also when rotated to landscape. However, when rotating back to portrait the page seems to shift left, or not zoom correctly, and there is a strip of white space down the right-hand side. This white space also seems to be present on first loading in portrait as the user can swipe the page left
Rather than complicating the explanation any further, here's a link to a sample page where this behaviour is occurring. Have a look on an iPhone, then have a look at the home page which does not have this issue.
If you need to see anything further, just me know :)
Fixed it! The issue was coming from one particular div - to find it, it was a process of deleting the different elements until the issue went away.
To fix it I needed to add overflow-x: hidden to that div and it sorts it out! Hope this is useful to others with a similar issue.
I had the same problem, I fixed it by setting:
html, body { width:100%; overflow:hidden; }
This problem occurs when width of any division is greater than the width of iPAD's screen.
In my case, some divisions were having size of 1000px, so I just went for width:auto and it works. overflow-x:hidden also does the same thing, but is not a preferred way.
I don't have an iphone to test this on but I have come across something similar with websites I've created in the past. In my case its because there was a bug in safari mobile that messed with the scale when going from port to land.
The following code fixed it for me (can't remember where I got it from at the moment)
if (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPad/i)) {
var viewportmeta = document.querySelectorAll('meta[name="viewport"]')[0];
if (viewportmeta) {
viewportmeta.content = 'width=device-width, minimum-scale=1.0, maximum-scale=1.0';
document.body.addEventListener('gesturestart', function() {
viewportmeta.content = 'width=device-width, minimum-scale=0.25, maximum-scale=1.6';
}, false);
}
}
Using "overflow-x: hidden" solves part of the problem, but screws the scroll, acting with strange behaviors (as Jason said).
Sometimes, the hardest part is to discover what is causing the problem. In my case, after a few hours, if found that the problem was in Twitter's Bootstrap:
If you're using Twitter's Bootstrap with "control-group" zones for your forms, the problem could be there. In my case i solved the problem with:
.control-group .controls {
overflow-x: hidden
}
Now the white space on the right was gone :)
I'd like to add to Navneet Kumar's solution because it worked for me. Any div tag styled with width=100% cannot also have left or right padding. The mobile browsers (I noticed the problem on iPhone and Android devices) interpret the div as having a width greater than 100%, thereby creating the extra space on the right side. (I knew this regarding fixed widths, but not percentage widths.) Instead, use width=auto in conjunction with padding.
I know it's a while since this topic was opened but I came across a similar situation and found it was because I had an element with the following properties right: -999999px; position: absolute; hidden off screen.
Changing the above to left: -999999px; position: absolute; solved the same issue the OP had (white screen to the right and ability to swipe right).
I'm using Bootstrap 3.3. I tried all of these solutions, and nothing worked. Then, I changed my <div class="container"> to <div class="container-fluid"> in the section that I was having trouble with. This solved the problem.
I tried all what has been suggested here, nothing works. Then I've relized that it connect with scale of page. So then I added <meta name="viewport" content="width=device-width, initial-scale=1.0"> to header.php in my main theme's folder and it 's fixed problem.
Seems as though results are varying for different circumstances but a sitewide
html, body { width:100%; x-overflow:hidden; }
seems to have worked for me!
Fixed!
Had a similar problem. Fixed it by setting the width to a current device width.
body, html {
max-width: 100vw;
margin: 0 auto;
overflow-x: hidden;
}
SOLVED ¡¡
Since installing protostar joomla template 3.X and start adding content in the module K2 I noticed that annoying scroll with a blank space on the right side, visible especially in iphones.
A correct partial answer was gave for Eva Marie Rasmussen, adding to the body tag in the file template.css these values:
width: auto;
overflow-x: hidden;
But this solution is only partial.
Search div class or label that is causing this problem and once detected add to that class in the file templete.css the same values:
width: auto;
overflow-x: hidden;
In my case add to the class "span" these two lines to finally look like this:
[Class * = "span"] {
float: left;
min-height: 1px;
margin-left: 20px;
width: auto;
overflow-x: hidden;
And it´s working now¡¡

Line artifacts in mobile Safari

Safari renders black lines in between divs on my website at some scales. It is particularly bad when it breaks apart an image that is chopped in two different divs for a button or something. I can't put a BG in the parent of the two divs because they are transparent .pngs. Any solution or just deal with it?

TravisO also has the same problem, and I changed how the page was laid out, originally it was a simple table with 5 rows, I removed the rows and just went with images and br, still happens. I've tried to remove all padding and margins via CSS but it was pretty obvious the problem isn't the browser rendering, but with the resampling the browser does to convert the page into a size that fits on the screen. You can see my broken page at:
http://www.apinkdoor.com/show/
TravisO, you should get rid of the img styling in your css!
If you use only this:
<style type="text/css">
*
{
margin: 0px;
padding: 0px;
}
body
{
background-color: #f00;
text-align: center;
}
</style>
it should render properly on your iPhone!
This issue is a result of a rounding error produced in mobile safari when it rescales background images for display (it's a bug: http://openradar.appspot.com/8684766).
The solution is to increase the width of your right-button edge on its left side by 1 or 2px. Then adjust your CSS accordingly so the 1 or 2 pixels you added are not displayed by default.
The following CSS, added to the problematic div with a specified background-image, is what fixed it for me. Anything less than 3px would still show light artifacts at some Safari zoom levels.
margin-top: -3px; /* for Mobile Safari dark line artifact */
padding-top: 3px; /* for Mobile Safari dark line artifact */
I found changing the background colour of the element with the 'grey border' around it worked for me.
Adding an initial-scale value to the viewport metatag resolved this issue for me.
<meta name="viewport" content="initial-scale=1.0">
I had a similar problem when displaying a .png-image in a div-tag. A thin (1 px I think) black line was rendered on the side of the image. To fix it, I had to add the following CSS style: box-shadow: none;

How can I create a footer/toolbar in an iPhone web app?

I'm working on a web app and I need to get a div to stick to the bottom of the viewport. Always viewable and always on the bottom of the viewport. There's an example of what I want here: footer. Unfortunately, this doesn't work on the iPhone. I can think of some ways to do this using javascript but I would rather not. Any ideas on how to get this effect on the iPhone using only css?
This situation has changed with iOS 5. Now you can use overflow:scroll or position:fixed and it will do what is expected. For example, this type of code:
<header style="
position: fixed; top: 0; left: 0;
width: 100%; height: 20px; font-size: 20px">
Heading
</header>
<article style="margin: 20px 0">
Your page here
</article>
<footer style="
position: fixed; bottom: 0; left: 0;
width: 100%; height: 20px; font-size: 20px">
Footer
</footer>
...should work without problems.
Though there are still many devices running older iOS versions, so you might want to lazy-load Scrollability on older devices, which you can test with this javascript:
var isios = navigator.appVersion.match(/CPU( iPhone)? OS ([0-9]+)_([0-9]+)(_([0-9]+))? like/i);
// if that succeeds, it usually returns ["CPU OS X_Y_Z like",undefined,X,Y,Z]
if (isios && isios[2] < 5){
// load scrollability here. jquery example:
$.getScript("/js/scrollability.min.js", function() {
// code to run when scrollability's loaded
}
}
You can't. At least not the way you think.
You have to fake the entire thing is javascript. Use something like iScroll
It sort of sucks but Mobile Safari does not support any kind of fixed positioning at all. So you have to make the page size equal to the screen size and then use javascript to handle touches and set scroll offsets and animate scrollbars and what not manually.
This script I linked does a lot of that for you, but it's not as robust as a native solution would be.
Here is an example on how to combine CSS3, HTML, and JavaScript to create a navbar for the iPhone.
http://www.mindovercode.com/2010/09/12/iphone-navbar-using-xui/
ps: It does work in landscape mode.
Here is a working example, with code. It is not for the faint of heart:
http://doctyper.com/archives/200808/fixed-positioning-on-mobile-safari/
There is a new JavaScript for this that works much easier: http://joehewitt.github.com/scrollability/
Therefore in iOS 5 there will be fixed position and overflow scroll available!
