I use the below html.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=device-width, user-scalable=yes"/>
<title>Sample</title>
</head>
<body>
<div style="width: 250px; height: 50px; background: green;">250px</div>
<div style="width: 500px; height: 50px; background: yellow;">500px</div>
<div style="width: 1000px; height: 50px; background: red;">1000px</div>
</body>
</html>
I set UseWideViewPort to true
WebSettings settings = webView.getSettings();
settings.setUseWideViewPort(true);
From what I understand, the div with the 1000px should occupy the entire width, the one with 500px should scale to half the width and the one with 250px should occupy one-fourth the width.
But what really happens is the one with 500px and 1000px goes beyond the screen size. I have attached the screenshot for clarity. I also tried changing user-scalable=no with no effect.
How should I fix this?
What is happening is that since you have the
<meta name="viewport" content="width=device-width, user-scalable=yes"/>
and you specify the width in your divs, then an actual value of, say, 1000 pixels is being applied to the div. According to documentation:
When the value is true and the page contains the viewport meta tag, the value of the width specified in the tag is used.
If you want to achieve divs with widths in respect to one another, an easier ruote would be using percentages, something like:
<body>
<div style="width: 25%; height: 50px; background: green;">25%</div>
<div style="width: 50%; height: 50px; background: yellow;">50%</div>
<div style="width: 100%; height: 50px; background: red;">100%</div>
</body>
If you aim to have a 'wide' viewport, like a desktop, you should pass true and not specify a meta tag as mentioned:
If the page does not contain the tag or does not provide a width, then a wide viewport will be used.

My HTML has several inner divs with display: inline-block inside an outer div with text-align: center;. This is the expected behaviour: in a big screen, some divs will show up side by side (how many depends on the size of each inner div and the outer div) and the set will be center aligned. When the screen width gets narrower the divs will re-position, and in a small smartphone screen we'll have only one div per row, center-aligned.
This is my MCVE:
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta charset="UTF-8">
<title>Align center</title>
<style type="text/css">
body {
background-color: white;
}
div.container {
margin: auto;
max-width: 1000px;
text-align: center
}
div.block {
margin: 4px;
display: inline-block;
width: 320px;
height: 400px;
background-color: green;
}
</style>
</head>
<body>
<div class="container">
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
<div class="block"></div>
</div>
</body>
</html>
If you change the size of the window you'll see the divs repositioning (SO snippet is quite small to see this behaviour, but you can click "full page" and resize the window).
My problem:
In smartphones there is just 1 div per row, and this is exactly what I want. But my problem is that the div is not center aligned on iPhones, despite being perfectly aligned on Android phones.
Using the code above, this is the result in an Android phone, you can see that the white margins are the same on left and right:
But now on an iPhone:
The div is slightly positioned to the right.
What can I do to center-align the divs?
Note 1: I wrote Android and iPhone in the question's title because I'm not sure if this problem depends on the OS (Android vs iOs) or on the browser (mobile Chrome vs mobile Safari). I don't think this is a Safari problem, because the divs are OK on iPad and MacBook.
Note 2: It may not be an "alignment" problem: on iPhone, it's like the div was not "compressed" to fit the screen.
Add this in your head tags,
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
Remove div.container from your css
Change block css to
.block {
width: 100%;
height: 400px;
background-color: green;
display: flex;
justify-content: center;
align-content: center;
}
if you want to show the blocks 3 at a time in 1 row in full screen:
<div class="container">
<div class="col-lg-4">
<div class="block"></div>
</div>
<div class="col-lg-4">
<div class="block"></div>
</div>
<div class="col-lg-4">
<div class="block"></div>
</div>

Above code for responsive image works fine on iphone but when I open the page on android the image displays with a scrollbar on chrome. On firefox it works fine.
Update
The page works fine on firefox in responsive design view on desktop. It works fine on iphone. But it does not work as responsive as it's expected on android phone. On android phone, it shows scrollbars in browser and in email application as well.
How do I make image responsive so that it works on iphone, android, chrome, firefox and in an email as well ???
I have been fiddling with chrome, firefox and a custom browser on Android and with FF and chrome on a 24" screen on Windows 7 and they all show scrollbars.
Depending on the width and height of your image (actually its ratio: 3:2, 4:3, 16:9, 16:10 etc.) you will see scrollbars when resizing it on a screen with a different ratio than your image. I am not sure, but it may well be that the internal browser engines of FF and Chrome use the same kind of logic to handle image sizing (hense the same effect on Android's Webview and WebChromeClient views) and iOS does not.
You should ask yourself if it is worth all the trouble getting this issue worked out for you or simply accept it as it is (I'd opt for the last).
Have a look at the code below (download => Github renevanderlende/stackoverflow) It is not only an acceptable solution for your issue, but also adds some easy to understand Responsiveness to your page you can fiddle with!
The images in the code are from amazing Unsplash, a fantastic place to find high-quality public domain photos.
And if you are a beginner like me, a visit to Codrops really is a must. Great clear and free tutorials with awesome, ready to use code!!
Cheers, Rene

MAybe you should give a CSS code...
try it:
#media screen.... {
img {
max-width:100%;
}
}
Or you have overflowed any parent element
You have bigger the parent elements I think...
One of parent elements are bigger that phone display...check it
Try...
body {
margin-left: 0px;
margin-top: 0px;
margin-right: 0px;
margin-bottom: 0px;
overflow-x:hidden;
}
img, div {
max-width: 100%;
height: auto;
width:100%;
overflow-x:hidden;
}
A simple HTML page contains a div with overflow-y:auto inside of another div with overflow-y:auto. This page scrolls normally on touch devices with IOS Safari and Android Chrome browsers.
However, if I open the same page in a native Android v.4.0 to 4.3 browser and scroll the outer div, the inner div does not move synchronously with the remaining content and jumps to its place only after some delay.
The same happens if the internal div has overflow-x: auto.
Example page: http://jsbin.com/cojoluwo/1/
The code looks as follows:
<!DOCTYPE html>
<html><head>
<meta http-equiv='X-UA-Compatible' content='IE=edge' />
<meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>
<title>test</title>
<style>
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#content {
height: 100%;
overflow-y: auto;
}
#scroller{
height: 100px;
overflow-y: auto;
width: 200px;
border: 1px solid red;
}
</style>
</head>
<body class='sapUiBody'>
<div id='content'>
<div>
<p> some text
......
<p> some text
<div id=scroller>
<p>internal text
...........
<p>internal text
</div>
<p> some text
...........
<p> some text
</div>
</div>
</body>
</html>
Is it a bug? If yes, is there any workaround known?
there's no need for this:
#content {
height: 100%;
overflow-y: auto;
}
a scrollable div with a set overflow inside another scrollable div with a set overflow is not a good idea on mobile and since your css properties for #content are redundant and not useful, you can safely remove them and it will work

I have some html code and I load it to WebView. I need to set button width in percents (in order to not to depend on the screen resolution).
When I set button's width in percents I'm getting an error that page cannot be loaded butf I set it in pixels everything is okay.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type='text/css'>
body{ position: relative; }
button { width: 50%; display: block; position: relative; }
</style>
</head>
<body style='text-align:justify;color:white;'>
Some text
<br/>
<button>Boo!</button>
</body>
</html>
Any thoughts?
EDIT:
The solution was found based on #Zak's advice, i.e., by calling the js function after the page was loaded, getting the screen width and setting it to the element.
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script language='javascript'> function SetWidth(){ d = document.getElementById('but'); d.style.width=screen.width/2; } </script>
<style type='text/css'> body{ position: relative; } button { display: block; position: relative; } </style>
</head>
<body style='text-align:justify;color:white;'>
Text<br/>
<button id='but' >Scary!</button>
<script> window.onload=SetWidth; </script>
</body>
</html>
I have done this with DIVs that I need to be exactly X percent of screen resolution. The way I accomplished this was using JQuery after the page has loaded, because JQuery can detect exact screen width, then you can do the math, and set a width to exactly X pixels.
$(document).ready(function() {
var = myWidth = screen.width;
myWidth = myWidth / 2;
$('#button').width(myWidth);
});
I havent checked that.. But the concept uis sound I assure you
Also: Make sure this code is at the BOTTOM of the page to ensure it is rendered AFTER the page elements have loaded.
Note: I'm using jQuery and jQuery Mobile.
I have a mobile page which seems to work okay in iOS, as far as respecting elements' positioning when zooming (or pinching). In Android, this is another story. Employing the Android SDK Emulator, all of my content is getting squeezed. I know there's a way to enforce that the content does not shift when zooming; I've seen it on desktop websites while using the Android browser. Disabling zooming is not the answer because I have an image on the page and I want the user to zoom in on said image.
To sum up:
I want to keep all content undisturbed when zooming (enlarging).
Thank you very much for any help.

Update
I figured out if I specify a set width on the page like this:
<div data-role="page" id="Index" style="width:320px;">
The zooming does not disturb the contents of the page.
But I want to maintain a liquid layout, or a fluid (hybrid) layout, at best. I can use JavaScript to specify the width of the div to the width of the device. Other than JavaScript, or setting a specific pixel (or em) width in CSS, is there an equivalent method using a liquid layout design?
Thank you.

Unfortunately, if the orientation changes, then this won't be helpful, especially when zooming.
I suggest opening one of those desktop websites you are talking about and cheeking there hrml and css with some browser plugin . thats what i do all the time :)
