I've a website that I'm building which is 700px width on desktops and mobile. On the desktop the 700px div is centred. On mobile the 700px div just needs to fill the screen.
Test code below
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<meta name="viewport" content="width=700" />
<style>
div#wrapper
{
width:700px;
margin-left:auto;
margin-right:auto;
}
</style>
</head>
<body>
<div id="wrapper">
<img src="/test.jpg" alt="Test image 700px width in 100px strips" />
</div>
</body>
</html>
This works fine across desktop browsers and most mobile phones. However on my daughters cheapo smartphone the browser zooms right in and only displays about 350px.
How should I approach this issue. You would think that it would be an easy situation to resolve but it's proving not too be! Messing about with the other meta tag attributes (initial zoom etc) has no effect on this particular smartphone.
The Huawei phones browser is Agent: Modzilla/5.0(Linux; U; Andriod 4.2.2;en-gb;HUAWEI Y330-U01 Build/HuaweiY330-U01)AppleWebKit/534.30(KHTML, likeGecko)Version/4.0 Mobile Safari/534.30
Use this
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
Explanation:
A <meta> viewport element gives the browser instructions on how to control the page's dimensions and scaling.
The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).
The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.
Here is an example of a web page without the viewport meta tag, and the same web page with the viewport meta tag:

Read this - https://css-tricks.com/snippets/html/responsive-meta-tag/ and this http://www.w3schools.com/css/css_rwd_viewport.asp
I don't have an Android device to verify this, but perhaps this would be solved with a relative width and a maximum width:
<style type="text/css">
div#wrapper
{
width:100%;
max-width:700px;
margin-left:auto;
margin-right:auto;
}
</style>
max-width overrides width when its conditions are met, so a smaller display like that on your daughter's phone should use a full width while a larger display would only be 700 pixels wide.
(I added the type attribute to your <style> tag for completeness. Your code should render just fine without it.)
Try this, hope it will solve your problem
<meta name="viewport" content="width=device-width"/>
instead of
<meta name="viewport" content="width=700" />
I would set your CSS width to 100%, not 700px. It's generally best to avoid hardcoding dimensions when possible. Also as suggested by another answer, max-width could be useful as it overrides width when specified.
You could then use screen size media queries(https://css-tricks.com/snippets/css/media-queries-for-standard-devices/) to put a border div around the image on large displays.
Add the below link inside the head tag
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
Style Sheet
<style type="text/css">
#media only screen and (max-width: 699px)//media query for the resolution below 700px {
div#wrapper
{
width:100%;// this will took full width
}
}
</style>

I have combined several large images into a Sprite. Each image when displayed full size, is larger than my iPad screen size. If there is a single image in the sprite, the full image is available to view. I simply scroll to the right or down to see the parts of the image which don’t fit on the screen initially.
If there are several images in the sprite, I can scroll right to see the part of the image which doesn’t fit on the screen initially, however the height of the image is truncated to fit the screen height, so I can’t scroll down to see the rest of it. If I turn my iPad from landscape to portrait the displayable image enlarges to the portrait height of the screen.
How can I fix this?

I don’t know why the monthly image sprite behaved differently from the single image sprite, but simply putting the image inside a div solved the problem.
<div>
<img id="img1" src="bates-sprite.jpeg" alt="Camberley Mail front page report">

In the following piece of code, I have attempted to make the width of a picture (a red square) equal to that of my — up to date — browser's viewport. However, the size of said picture is far from the latter's (as can be seen in this picture). The picture is 1560px high and 1560px wide.
I've tried every potential solution I could find online, including using the <picture> tag with the sizes attribute or trying to change the picture's height with vh instead, and nothing worked.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>foo</title>
</head>
<body>
<img src="bar.jpg" width="100vw" alt="bar">
</body>
</html>
How can I fix this sizing issue while keeping the width relative to the viewport (and therefore not using a fix such as width: 100%;)?
The <img> width attribute is always unit-less, and refers to pixels.
width: The intrinsic width of the image in pixels.
To apply a width with vw units, you must use CSS.
<style>
.full-width {
width: 100vw;
}
</style>
<img src="bar.jpg" class='full-width' alt="bar">
You need to use the style property, style="width:100vw", not the width attribute. The width attribute is always in pixels, so width="100vw" is translated into width="100px"
I made a very simple site www.abasi.info/viewport
Consists out of:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<p><img alt="18" src="18.gif" style="height:55px; width:550px;"></p>
</body>
</html>
The numbers should go until 18. But with my Android Phone (Version 2.3.6) the viewport doesn't adjust. It is zoomed in to much. I just had this one picture in the site (nothing else). And if the above viewport would work it would show all the numbers in the pictures until 18. It is very strange.
You need to make the Image 100% width and auto height, so the ratio won't mess up.
example -
img{
width:100%;
height:auto;
}

you also can use max-width, but make sure you define the image dimensions first.
To limit the viewport to 550px you will have to change it to-
<meta name="viewport" content="width=550, maximum-scale=1, user-scalable=no">
I've got some simple HTML/CSS that I want to roughly fill the browser window height-wise on a portrait-oriented iPhone and iPad. The code I've developed works great on the iPhone, filling it nicely. However, on the iPad it takes up maybe half of the screen. I've tried all kinds of scaling, width, height, etc. settings on the meta viewport tag, but can't find something that works for both.
Is it possible to set it to work on both equally well? I also want it to work well on Android if possible.
Here's the code I'm using:
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0,
user-scalable=0, target-densitydpi=medium-dpi, maximum-scale=1.0"/>
<style>
.box {
border:0px solid ddd;
text-align:center;
font-size:750%;
font-family:Helvetica;
font-weight:bold;
margin:0 auto;
padding-bottom:10px;
}
.gaptop {
margin-top:10px;
}
</style>
</head>
<body>
<div class="box">+</div>
<div class="box">–</div>
<div class="box gaptop">3</div>
</body>
</html>

Hope this may help you.
Consider the following rudimentary html code block:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>iPad test</title>
<meta name="viewport" content="width=device-width">
<style>
body
{
margin:0;
}
#content
{
margin: 0 auto;
width: 980px;
border:1px solid #c4c4c4;
background-color:#f5f5f5;
}
</style>
</head>
<body>
<div id="content">
A small amount of content
</div>
</body>
</html>
When viewed on an iPad, the main content area of 980px will not be auto zoomed to fit the iPad screen. However, if you replace A small amount of content with a large amount of content, ie... enough to cause vertical scrolling, the page is auto zoomed on the iPad.
Does anyone know why this is? I have been searching high and low and can't seem to find a way to force the auto zooming to occur when there is minimal content on the page.
Changing the viewport content to width=980 fixes the issue of course, however I am creating a responsive website, therefore the viewport needs to be device-width.
I am using a media query to alter the CSS for the content area on smart phones (to 100% width), and I was hoping to use the standard desktop version of the website for iPads.
Any ideas would be much appreciated.
Note: I am testing on an iPad with retina display, I'm not sure what happens on older models.
After a break from this, I came back with a different angle - if setting the viewport width to a specific value fixes my issue for the iPad, why not do just that.
So the solution for me was to default the viewport width to device-width to handle smart phone devices, then detect for iPads and adjust the viewport width:
<meta name="viewport" content="width=device-width">
<script type="text/javascript">
if(navigator.userAgent.match(/iPad/i)) {
viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=980');
}
</script>
Thanks for your suggestions insertusernamehere
Try this:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
The whole content will fit afterwards.
