In Bootstrap 3, there seems to have been an issue with the fluid grid causing a horizontal scrollbar to appear on small devices. My question is different...
I'm not getting any scrollbar, unless I click a text input. On an iPhone, there is an automatic zoom on the current field. This is ok (I guess), but after leaving the field, the zoom is not removed, so the content is clipped and there's an ugly horizontal scrollbar.
Is there a way to prevent the zoom? Or maybe tell mobile safari to set the zoom back to what it was?
First: you can create fluid-responsive tables. But you do not need it. If you don't give the <table> the class="responsive" the horizontal scroolbar doesn´t appear.
If you want to disable the zoom on small devices use this:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
Hope, it helps :)

I have an email that includes a long table and doesn't show well(gets jammed) in iOS mail because the width of the table is huge. I don't know how to enable horizontal scrolling for iOS mail application so the html emails will not wrap around.
Thanks

It's not a question of enabling horizontal scrolling. As long as your tables have defined widths you should be fine- the scroll bars will be there.
You could also define your viewport so zooming is disabled:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"/>
Maybe I'm not understanding your issue. Could you post a screengrab?
I'm trying to recompile an app for iOS 7, since nothing of the old one works so far.
One of the many problems is that I'm using some inputs inside UIWebViews. Text inputs, pickers etc.
Now, when the iOS 7 shining white keyboard appears, all the bottom fixed elements in the webpage (such as, confirm buttons) are scrolled upward, as if the 'top' of the virtual keyboard is the new bottom of my UIWebView. This is a substantially different behavior from iOS6.x
Is there any magic trick to make the virtual keyboard behavior work like it used to, without injecting JS/CSS to the webView?
This fixed the problem for my cordova app. I'm not sure if it applies to you but just in case.
Check your html meta tags for something like this:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">
Replace it with this:
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0, target-densityDpi=device-dpi" />
In our case this would fix itself as soon as user scrolls. So this is the fix we've been using to simulate a scroll on blur on any input or textarea:
$(document).on('blur', 'input, textarea', function () {
setTimeout(function () {
window.scrollTo(document.body.scrollLeft, document.body.scrollTop);
}, 0);
});
I ran across exactly the same problem & gave up after two days of experimenting. It seems that:
a) all bottom-fixed elements go upwards so that their bottom offset is relative to the top edge of the keyboard
c) all top-fixed elements stay in their original position (do not move upwards as they used to) - note that top-absolute elements work ok.
The only solution I found was to have a custom iPad stylesheet that replaces all fixed elements with absolute elements, sets the css bottom property to auto and uses top instead
Opposum, your solution worked for me but only when the scale was set to 1.0. If I set it to 0.9 then it would be like it was before your suggested fix. I set initial-scale, maximum-scale, and minimum-scale to 0.9 and the bouncing effect of the fixed objects when the keyboard appeared was still happening.
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 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
I developed a web app for the iPhone which has a page with a textarea widget. When I begin editing the contents of this textarea widget Safari zooms in and makes the text really, really big. Now I can't see the document anymore, just a little postage stamp sized piece of it.
Are there any properties I can set which will keep mobile Safari from doint this? I just want the textarea font to stay the same size when I edit its text. Thanks.
You can add:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no">
to your HTML header.
You would need to set your textarea font-size to 16px and have an initial-scale of 1.0.
But if your app is not really designed for the iPhone, that is, if it’s essentially a normal web page that users should be able to scale, then you should probably just become okay with it. The worst thing to do to your users is show them 6pt text they can’t zoom, you know? Some of them won’t have perfect vision.
