There is a viewport issue on vertical orientation of the mobile.As you can see,below the footer,there is a white space which fills the screen.If i turn the orientation on horizontal, the viewport works fine,same for tablets,desktop,etc..this issue persists only on vertical orientation of the mobile.Is there any way to fix this?
I already have this metatag:
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
You need use media queries:
Start with your mobile (base) styles first in your CSS (This is typically a single column layout).
Then use media queries using min-width at progressively larger viewports breakpoints (This is where you would apply your grid styles).
Use each each larger min-width breakpoint to override the previous
styles to provide an appropriate layout based on the viewport size.
Make sure to use the <meta name="viewport" /> tag in your html to ensure optimal mobile presentation.
Using Cascading min-width media queries will allow you to know exactly what properties are being applied based on the screen width and make troubleshooting your css easier.

.half {
float: left;
margin: 0;
width: 50%;
}
.row:after {
content:"";
display:table;

Mobile browsers handle orientation changes slightly differently. For example, Mobile Safari often just zooms the page when changing from portrait to landscape, instead of laying out the page as it would if originally loaded in landscape. If web developers want their scale settings to remain consistent when switching orientations on the iPhone, they must add a maximum-scale value to prevent this zooming, which has the sometimes-unwanted side effect of preventing users from zooming in:
<meta name="viewport" content="initial-scale=1, maximum-scale=1">

I hope it helps.
I'm not sure if the " marks make a difference but you could always try.
<meta name=viewport content="width=device-width, initial-scale=1">

Edit 1: Try working with Media Queries if that solves the problem https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries
Did you try maximum-scale?
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

i have a issue in my Android page on input focus, i can't disable auto-zoom
only in (orientation: portrait) :
http://ufficio.web-project.it/smlapalma/akenta/invia-scusa.html
I have already try this codes:
meta name='viewport' content='user-scalable=0'
or
input:focus { font-size: 16px!important}
but nothing.
Thanks in advance.

This would be the right meta-tag:
<meta name="viewport" content="width=device-width, user-scalable=no">
But, this won't solve your problem because this meta tag doesn't change the size of your sites components. Let's say you have a <div> with the width of 1200px, the user's browser will view it 1200px wide.
I looked at your website, and the problem lies in the foundation of your CSS. You are using px a lot, where you might want to use %. If you use percentage, you will see that your site adjusts to the screen size. You should also use em as unit for font size instead of px. My tip is to avoid px-units as much as possible.
But of course, this means you will have to change your entire CSS, which is much work. But eventually this will solve your problem.
When I test my development website on any Android mobile phone, the website doesn't fit full screen on the mobile screen. Attached is the snapshot. I' am just trying to make it mobile friendly.
I' am using wordpress with Twitter Boostrap to make my website. On my head tag, I have few meta tags that I found on the Internet for mobile friendly websites. Please note that this is not a responsive website.
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9,chrome=1">
Please help?
If you were designing a responsive site, but want to "fix" the width of the site in mobile i.e. 800px max width, I found that my only solution was to update the initial scale size. What worked nice for me was something like this, notice the "initial-scale" value:
<meta name="viewport" content="width=device-width, initial-scale=0.4">
Hope this helps someone!
I have had recently the same issue on tablets/phones and fixed that with the following snippet.
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
#-webkit-viewport { width: device-width; }
#-moz-viewport { width: device-width; }
#-ms-viewport { width: device-width; }
#-o-viewport { width: device-width; }
#viewport { width: device-width; }
</style>
<script>
// Important for windows phone 8
if (navigator.userAgent.match(/IEMobile\/10\.0/))
{
var msViewportStyle = document.createElement("style");
msViewportStyle.appendChild(document.createTextNode("#-ms-viewport{width:auto!important}"));
document.getElementsByTagName("head")[0].appendChild(msViewportStyle);
}
</script>
Make sure you're using the responsive classes included with Bootstrap in order to allow for design within the Bootstrap framework. In Bootstrap, all content is on a 12 "column" grid, and then split up based on that grid.
In Bootstrap 2.x
<div class="container">
<div class="row">
<div class="span6">
Content here
</div>
<div class="span6">
Content here
</div>
</div>
</div>
will produce two divs that span the width of the page.
In Bootstrap 3, they changed their class names slightly to account for different window sizes. The same example, provided you're on a mobile, device would be:
<div class="container">
<div class="row">
<div class="col-xs-6">
Content here
</div>
<div class="col-xs-6">
Content here
</div>
</div>
</div>
You can remove responsiveness in Bootstrap 3 by following these steps:
http://getbootstrap.com/getting-started/#disable-responsive
More information can be found here: http://getbootstrap.com/css/#grid
I know it's an old question but since it shows up in google I thought I'd share the solution I came up with, in case anyone else needs it:
If your website isn't responsive, you don't need the extra meta tags at the header. Try to remove them and it should work as expected.
No one ever quite answered this similar question,
Blurry images on stock android browser
So I'm going to post my own version specific to my situation.
The problem is that position:fixed causes child image elements to be blurry in some android browsers. In my case, it causes the stock browser of Galaxy Note v1 running Android 4.0 to experience this issue. Others have said the same thing for some Galaxy S3. Here's my code:
Preview # http://jl.evermight.net/blurryposition/
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, maximum-scale=1.0,initial-scale=1.0, user-scalable=no" />
</head>
<body>
<div id="top-nav-container"
style="
display:block;
top:0px;
position:fixed;
width:100%; height:5.2rem;
">
<a style="background-image:url(logotest_big.jpg);
background-size:20%;
display:block;
width:500px;
height:200px;
"></a>
</div>
</body>
</html>
You'll notice that the OPTIX Testing logo is blurry at first. If you remove position:fixed from the #top-nav-container, then the logo is crisp and clear. So my question is, how do I keep both position:fixed and a crisp logo?
In my real website, the top navigation is supposed to stay fixed while you scroll through the site. I tried using position:absolute and using javascript to reposition the top navigation on scroll, but that caused a whole bunch of jumping/flickering effects. So if I can't use position:fixed or position:absolute to fix the top navigation to the top of a mobile web browser, what are my other options? How do other mobile websites achieve this result?
Additional Info:
I did some more experiments with the resizing image, changing view port, and changing the position:fixed/absolute and came to some interesting results. See below:
position:fixed no-background-size with-viewport - fuzzy
position:fixed no-background-size without-viewport - crisp
position:fixed background-size:20% with-viewport - fuzzy
position:fixed background-size:20% without-viewport - fuzzy
position:absolute no-background-size with-viewport - fuzzy
position:absolute no-background-size without-viewport - crisp
position:absolute background-size:20% with-viewport - crisp
position:absolute background-size:20% without-viewport - crisp
Here's how to read this chart:
first column states whether #top-nav-container is using position:fixed or position:absolute
second column states if i used background-size:20% or if i omitted it
third column states whether i included the <meta viewport> tag in the head
fourth column states whether the optix testing logo is fuzzy or crisp.
Looking at the results, you can see that the only time you get a crisp image with a container that has position:fixed is when an image has not been stretched or compressed via background-size or or with the view port. Also, the only time you get a fuzzy image with a container that has position:absolute is when an image has been stretched with background-size and with a viewport.
Using position: fixed is still a bad idea on mobile devices. The overwhelming majority of websites fall back to a static header for mobile views (ie. no floating navbar).
I experienced similar issues recently, as illustrated in this question.
A few resources for you:
Read this article on Quirksmode to learn about the problem: http://www.quirksmode.org/blog/archives/2010/12/the_fifth_posit.html
See which mobile browsers support position: fixed in this table: http://caniuse.com/#search=fixed
add inside top-nav-container.
<div id="top-nav-container"
style="
display:block;
top:0px;
position:fixed;
width:100%; height:5.2rem;
">
<a style="background-image:url(logotest_big.jpg);
background-size:20%;
display:block;
width:500px;
height:200px;
"></a>
</div>
I got this problem too when creating fixed action bar with div using background-image as icon. But when I add Text in that action bar, that background-image become crisp. So I just add as replacement for Text if I don't want any Text on my action bar.
Sorry for my bad English :D
Instead of user-scalable=no change it to user-scalable=0
try this:
img {
transform: scale(1) rotate(0) translate3d(0,0,0);
}
<div style="position:fixed;"><img/></div>
<div style="position:fixed;"></div><!--add it-->
add a "fixed" element follow the "fixed", just like up.
I have an application with several screens as HTML loaded in WebView.
The default CSS for texts is font:normal 14px Arial, Helvetica, sans-serif, which, as I assumed, is supposed to look the same (in terms of font size) on all devices.
For some reason, on some devices the font looks like size 26+ which causes the font to overflow in constricted elements.
What am I doing wrong?
there are other parameters play role in determining size of elements in HTML page in Android like :
<link rel="stylesheet" href="css/hdpi.css" media="only screen and (-webkit-min-device-pixel-ratio:1.5)">
<meta name="viewport" content="user-scalable=no, width=device-width, target-densitydpi=device-dpi">
try to integrate those parameters and you will get more stable view ..and then later you may update those values through JS or activity ..
good luck
Try this setting for webview .. this sets the initial scale for the WebView
setInitialScale (int scaleInPercent)
I have a fixed-width web page (640 pixels wide). I would like this page to shrink to the width of a mobile device. However, if the device's native width is larger than 640 pixels, I do not want it stretched. Seems simple enough:
<meta name="viewport" content="width=640, maximum-scale=1.0" />
This works as expected in iPad/iPhone. However, on an Android tablet (ex. in landscape mode), the content gets scaled up to fit the display. In other words, Android is simply ignoring maximum-scale=1 . You can see an example page with the problem here. For the sake of completeness here is the source:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Test Viewport</title>
<meta name="viewport" content="width=640, maximum-scale=1.0" />
<style>
div.bar {
position: absolute;
width: 636px;
height: 50px;
background-color: yellow;
border: 2px solid black;
left: 50%;
margin-left: -320px;
}
</style>
</head>
<body>
<div class="bar">
</div>
</body>
</html>
I've been doing a lot of researching and experimentation with the viewport meta-tag. I've read just about everything on the topic, but haven't seen this seemingly basic issue mentioned.
Two notes:
This is not a target-densitydpi issue
Setting the viewport width to device-width is not helpful in this case because the content width is fixed and larger than (for example) a phone's portrait device width. If I set width=device-width, the page will not automatically be scaled down to fit the phone..
Thanks much.
After more banging my head against a table, I have found a solution:
Unfortunately it seems that iOS and Android simply behave differently (Android is very clearly not doing what the spec says by ignoring maximum-scale). The solution is to specialize based on resolution using JavaScript:
If the screen width (see note below) is greater than or equal to the fixed page width (640 in my example), then set the viewport meta-tag's content width to the screen width
Else set the viewport meta-tag's content width to fixed page width (640)
Presto. Lame that it requires JavaScript specialization, but such is life.
Note that the Javascript screen.width on iPad/iPhone is incorrect if the device is landscape mode (the iPad still reports the portrait width instead of the landscape width, unlike Android which gets it right in this case!). Therefore, you'll need to check window.orientation on iPad/iPhone and use screen.height instead of screen.width if you are in landscape.
I'd rather use
width=640, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, target-densityDpi=device-dpi
Instead of just the Max scale property...
The target-densityDpi property si Android specific, maybe it can fix your problem.
