I Have Written The Following Code . It Is Showing Absolutely Fine In Mozilla and Chrome . But IN Internet Explorer , it is not center aligned and display at the left side . Here Is The Code:
<html>
<head>
<title>ProgramEngine Website Registration</title>
<style type="text/css">
div#login
{
background-color:#f1f1f1;
width: 510px;
height: 1024px;
border: 1px solid grey;
margin-left: auto;
margin-right: auto;
}
</style>
</head>
<body>
<div id="login"></div>
</body>
</html>
So Can AnyBody Suggest Me What is the Problem And How To Overcome It.
You can use jquery for good solution.
See this Link
$(document).ready( function(e){
var screen = $('body').width();
screen -= 51; //51 is width of div
screen /= 2;
$('#login').offset({top:0,left:screen});
});
if you need use top in offset value.
Here, browser can't makes problem.
Are you using correct DOCTYPE? Without the DOCTYPE, IE automatically goes into Quirks render mode - this is your problem, probably.

After pulling all my hair out it has come down to this minimal html page that seems to be rendering wrongly on iOS:
<!doctype html>
<html>
<head>
<style type="text/css">
#fold
{
background:url(https://s3.amazonaws.com/gigantt_pub_imgs/2012/07/1342078193.png) top left;
min-height:350px;
}
#features
{
background:url(https://s3.amazonaws.com/gigantt_pub_imgs/2012/07/1342078193.png) top left;
min-height:350px;
}
</style>
</head>
<body>
<div id="fold">
</div>
<div id="features">
</div>
</body>
</html>
When viewing in iOS (or for that matter in the iOS simulator) you can see a while line between the two blue divs.
This white line disappears if you zoom in. And of course it's not visible in any other desktop browser I've tried, either.
So, am I going nuts or is anybody else getting this? Any idea how to work around it?
It could be construed as a bug (I think it is) - but it has to do with the way iOS handles background images.
The quick answer - add a negative margin to one of your elements. See this JSFiddle.
The relevant portion is this:
#features
{
background:url(https://s3.amazonaws.com/gigantt_pub_imgs/2012/07/1342078193.png) top left;
min-height:350px;
margin-top: -2px;
}
You can target this using media queries.
I am using chrome version 18.0.1025.162 m
I have html file with iframe within it.
i cant change the containing page or its css (main.htm)
i can only change the iframe (show.htm) and its css.
The problem is that when i scroll down and then scroll back up then the adminbar div get replicated several time.
I am attaching 2 screenshots the first one is the screen before scrolling and i also add the code so that the bug can be reproduced.
I think it may be a bug in chrome, i am not sure.
I would like to know if it is a a bug and more importantly if there is a work around by only changing the iframe and that it does not include removing the background color from the iframe.
(removing the background color from the iframe solve the issue but i need the background color)
so this is how it looks:
before scrolling:
after scrolling (admin bar get replicated on screen)
now code to reproduce the bug in chrome
first file - main.htm (i cannot change this code)
<!-- main.htm -->
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en-US">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style type="text/css">
#adminbar
{
background-color: #464646;
height: 28px;
position: fixed;
width: 100%;
top: 0;
}
#body-content
{
float: left;
width: 100%;
}
</style>
</head>
<body >
<div id="body-content">
<iframe src="show.htm" width="100%" height="943"></iframe>
<div id="adminbar" class="" role="navigation">
</div>
</div>
</body>
</html>
and the show.htm
<!-- show.htm -->
<!DOCTYPE html>
<head>
<style type="text/css">
body
{
background: #e0e0e0;
}
</style>
</head>
<body>
<br/>
<p style='margin-bottom:500px;'>bazinga</p>
<p style='margin-bottom:500px;'>bazinga</p>
<p style='margin-bottom:500px;'>bazinga</p>
</body>
</html>
i think i found a workaround.
i created a file background.png which has one pixel with the color i want (#e0e0e0).
i then replace this:
body
{
background: #e0e0e0;
}
with this:
body
{
background: #e0e0e0 url(background.png) repeat-x;
background-attachment: fixed;
}
Add -webkit-transform: translate3d(0,0,0); to your body-content CSS
CSS
#body-content {
float: left;
width: 100%;
-webkit-transform: translate3d(0,0,0);
}
This seems to force Chrome to use your GPU and smooth out the rendering issue.
UPDATE: Since you can't change main.htm, what about changing the background color of show.htm to a background image of the same color? I tested this and it worked. Is that a possibility?
I recreated your setup and then added a script to the body of show.htm. As a quick measure I added a name="if1" to the <iframe /> in main.htm, but you could always find a handle on the element without using an explicitly assigned name.
It seems to solve the issue for the dummy setup that you provided, if and only if main.htm is scrolled all the way to the top. Think it's weird, join the club! See if this works for the real thing... Either way, it may just be a nudge in the right direction! :)

var _parentScale = parent.document.body.style.webkitTransform;
parent.document.body.style.webkitTransform = _parentScale;
}
</script>
</body>
</html>
I also tried to experiment with the following until it became bed-time!
<script type="text/javascript">
window.onscroll = function(){
console.log("It's 'Doctor' Sheldon Cooper!");
//parent.document.if1.document.body.style.webkitTransform = 'scale(1)';
var _me = document.body;
_me.style.webkitTransform = _me.style.webkitTransform;
//_me.style.display='none';
_me.offsetHeight
//_me.style.display='block';
var _parent = parent.document.body;
_parent.style.webkitTransform = _parent.style.webkitTransform;
_parent.style.display=_parent.style.display;
_parent.offsetHeight
//_parent.style.display='block';
}
parent.window.onscroll = function(){
console.log("But. You're in my spot!");
//parent.document.if1.document.body.style.webkitTransform = 'scale(1)';
var _me = document.body;
_me.style.webkitTransform = _me.style.webkitTransform;
//_me.style.display='none';
_me.offsetHeight
//_me.style.display='block';
var _child = parent.document.if1.document.body;
_child.style.webkitTransform = _child.style.webkitTransform;
_child.style.display=_child.style.display;
_child.offsetHeight
//_child.style.display='block';
}
</script>
I also attempted to apply j08691's answer, using the following script, but it gave slightly unexpected results. I caused the absolute positioned top bar, to not be fixed, among other things!
window.onload = function(){
console.log("It's 'Doctor' Sheldon Cooper!");
var test = parent.document.getElementById("body-content");
test.style.webkitTransform = "translate3d(0,0,0)";
}
One may already exist, but if not, could you file this as a bug report on the relevent projects?
Improving / simplifying yossi's answer:
body
{
background:url('bg.png');
}
no need to declare bg-color or repeat-x, just needs a background image.
Tested on Chrome 18.0.1025.168, Mac OS X 10.6.8.
Remove the float: left; from your #body-content css and it will work just fine.
This looks to be a rendering bug in chrome. If you scroll back up really slowly, you'll notice that you get a solid colour from your admin bar as the colour of your iframe.
Incidentally chrome on OSX renders exactly the same.
#adminbar {
background-color: #464646;
height: 28px;
position: fixed;
width: 100%;
top: 0;
right:0px
}
#body-content {
float: none;
width: 100%;
}
It would help to get a live-demo/version of your actual website to do more thorough testing and sort the bug out.
In any case, I was able to reproduce the bug and then fix it (kind of):
Here's the 'show' css:
body
{
background: #e0e0e0;
height:100%;
width:100%;
z-index:9999;
position:fixed;
}
and Here's the link to my test page:
sotkra.com/t_main.html
last but not least, yes it is a bug and it caused by the flickering of the scrolling of the iframe content against the actual 'base' document. I've seen similar issues before but there was equally no documentation about it. They're just rendering bugs, usually caused by less than specific css or very very odd cases where it's nobody's fault save the browser's.

Using a gradient as your background image also works. This is preferable for me, because I don't have to create an image file and it doesn't generate an extra request on the client side.
body {
background: #FFF -webkit-linear-gradient(top, #FFF, #FFF) repeat-x;
background-attachment: fixed;
}
I made a web page with the following code and viewed it in Google Chrome.
<html>
<head>
<style type="text/css">
html {padding:30px; background-color:blue;}
body {margin:0px; background-color:red;}
</style>
</head>
<body>
hello world
</body>
</html>
The result is what I expected, a red box with a 30 pixel blue border that fills the entire web browser window. However, when I view it in Firefox, the red box is only the height of one line-height. In IE8, there is no blue border.
How do I make Firefox and IE8 display the same thing as what I see in Google Chrome?
Additional notes I tried adding different doctype tags to the page, but that only made it appear like Firefox, that is, the 1 line-height of red.
For this I think you have to resort to absolute or relative positioning; otherwise, your height/margin combo will push the bottom blue line off the screen. This works cross browser for this simple case. Hopefully it works for your more complicated use case.
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
body { background:blue; }
.first{
position:absolute; /* fixed also works */
background:red;
top:30px;
left:30px;
right:30px;
bottom:30px;
}
</style>
</head>
<body>
<div class="first">hello world</div>
</body>
</html>
if i understand you correctly, set your html & body width to 100% , height 100%
http://jsfiddle.net/Diezel23/Lv6Vw/#base
You could add an additional div:
<html>
<head>
<style>
body {
padding: 30px;
margin: 0px;
}
div {
width: 100%;
height: 100%;
background-color: blue;
}
</style>
</head>
<body>
<div>
ABC
</div>
</body>
</html>
Can somebody tell me how to make the work with IE9:
I am trying to make the "center" div to appear in the center.. It works fine with ff and chrome, but I have spend the last 1 hour trying to get it work with IE9. It keep going to the left!
The only way to make it work is by setting text-align to center on the parent container. Anybody knows any other way? More "proper"?
Thanks!
<html>
<head>
<style type="text/css">
#center {
width: 200px;
border: 1px;
margin: 0 auto;
}
</style>
</head>
<body>
<div id="center">
Hello World!
</div>
</body>
</html>
</code>
IE is notorious for not working without proper doctypes.
Try adding the HTML5 one
<!DOCTYPE html>
View the fiddle: http://jsfiddle.net/xavi3r/bGyPN/
Try removing </code> what is it referring to ?
<div id="center">
Hello World
</div>
#center
{
width:200px;
margin:0 auto;
border:1px solid #CCC;
}
I want my page's BODY not to be scrollable but a DIV inside the BODY should be scrollable.
I have this in my css file:
body {
overflow:hidden
}
.mainSection {
overflow:scroll
}
but it doesn't work and the DIV doesn't become scrollabel (it just shows two disabled scroll bars for the DIV)!
.mainSection needs to have a height. Otherwise the browser can not know what it should consider overflow.
Are you sure the style for your mainSection class is being applied? You can use a tool like Web Developer or Firebug (for Firefox) to make sure that the style is being correctly applied. Also if you just have one mainSection, you might want to use an id instead of a class. the tag in html would then be <div id="mainSection"> instead of <div class="mainSection"> and the css becomes #mainSection { ... } instead of .mainsection { ... }
Here is the whole thing well explained
http://www.w3schools.com/css/pr_pos_overflow.asp
You can experiment.
I had the same problem before, but I could manage to solve it just with overflow: auto;. Try it and it will work.
Updated
The full html code looks like this
<html>
<head>
<title>Test page</title>
<style type="text/css">
#scrollable_div{
overflow: auto;
width: 100px;
height: 100px;
border: solid thin black;
}
</style>
</head>
<body>
<div id="scrollable_div">my div text</div>
</body>
Works perfectly in any browsers. I tested myself in Chrome, IE, Safari, Mozilla, and Opera
