I used CSS to vertically center my web site however when it is viewed in the horizontal mode on an iphone, the site is cut off and not centered. How can I fix this?
Here is the css I used to center the site:
#wrapper {
width:850px;
height:650px;
position:absolute;
top:50%;
margin-top:-325px;
left:50%;
margin-left:-425px;
}
And here is the site:
http://www.maidmarianmuffins.com/
I need the result to be fully functional i.e. zoom & pinching functions must still work. :)
I would change the #wrapper properties from what you have to
#wrapper {
height: 650px;
margin: 5% auto 0;
position: static;
width: 850px;
}
The static positioning the default of each element, so no problem if don't include it. The margin value 5% represent the margin from top, the auto for the left and right and 0 for bottom.
I made a live example you can find and test it from your iphone here: http://jsbin.com/adino3/3
Have you tried this:
<!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" xml:lang="hr-HR" lang="hr-HR">
<head>
<style type="text/css">
#wrapper {
width:850px;
margin: 0 auto;
}
#wrapper_inner{
width:850px;
height:650px;
position:absolute;
top:50%;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="wrapper_inner">
Center me

I am trying to design a web form in ASP.NET. In that I am trying to set a background color to different empty divs. Normally a simple html code like below works:
<html>
<head>
<style>
#header{
width:100%;
height:20%;
background-color:lightblue
}
#nav-bar{
width:100%;
height:5%;
background-color:lightgreen;
}
body,html{
margin:0;
}
</style>
</head>
<body>
<div id="header">
</div>
<div id="nav-bar">
</div>
</body>
</html>
But if I use this same snippet in ASP.NET, I fail to achieve the desired result. The browser displays nothing. My aspx code is as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head runat="server"><title></title>
<style type="text/css">
#header {
background-color: lightblue;
height: 20%;
width: 100%;
}
#nav-bar {
background-color: lightgreen;
height: 5%;
width: 100%;
}
body, html { margin: 0; }
</style>
</head>
<body runat="server">
<div id="header">
</div>
<div id="nav-bar">
</div>
</body>
</html>
So how can I set a background color to an empty div in ASP.NET? Any help would be much appreciated. Thanks!
The problem is that your #headerand #nav-barhave percentage heights. You'll see if you change them to pxdimensions, they empty div's still show up. So your problem doesn't have anything with ASP.NET it's just a CSS issue.
If you want the heights to be responsive to the user's screen, you should try the vhtag. This stands for viewport height. So if you have 20vhfor example, it will take up 20% of the users screen height.
See my updated JSfiddle:
http://jsfiddle.net/0mr9z6hy/2/
percentage heights may work differently across browsers
but one problem is you have no height specified on the body so the height is only really the height of the actual content of your page which is not much.
html, body{
height: 100%;
}
I have tried literally everything I can think of. I have tried dozens of coding samples from the stack and tutorial sites. I cannot get this to work no matter what I do, and I'm absolutely at my wits end with trying to figure it out. Me and CSS don't get along.
Here is what I'm trying to do:
Static Header (always on the screen.)
Footer that always stays at the bottom of the page. (Scrolls with content, but if there isn't enough content will appear at bottom of the screen.
Left menu with background that goes all the way down to the top of the footer.
I'm having trouble getting the background to go all the way down. It is a normal problem of being unable to have 100% parents, relatives and absolutes. This code I have now works fine with the exception of the background. I'm honestly considering just making the background a image and have it repeat. Here is the code:
<!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>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
html, body {
margin: 0;
padding: 0;
height: 100%;
}
#main_wrapper {
min-height: 100%;
position: relative;
}
#header {
width: 100%;
background:#0F0;
height:42px;
position:fixed;
left: 0;
top: 0;
}
#content {
margin-left: 200px;
background:#F00;
}
#footer {
width:100%;
height:32px;
position:absolute;
bottom:0;
left:0;
background:#00F;
}
#content_wrapper {
padding-bottom: 32px;
padding-top: 42px;
overflow: auto;
}
#left_menu {
width:200px;
background: #FF0;
float:left;
}
</style>
</head>
<body>
<div id="main_wrapper">
<div id="header"></div>
<div id="content_wrapper">
<div id="left_menu">MENU</div>
<div id="content">CONENT</div>
</div>
<div id="footer"></div>
</div>
</body>
</html>
JSFiddle Source
As you can see in the Fiddle code, what I'm going for is to have the yellow background take up the whole height. And any content that gets added will cause the whole page to scroll, footer to move to bottom and header remain static. All of that works right now except for the yellow background color taking up the whole height.
The easiest thing to do would be to add an image to the background that repeats in the Y direction.
background-image:url(images/background.gif);
background-repeat:repeat-y;
This gets the job done, but there has to be a better way!
Im working with a XHTML 1.0 Transitional doctype html file, and I want to have a main div with 800px width and make it appears centered (not the div content, but the div itself).
I've used this on the past:
<!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></title>
<style>
<!--
html, body { margin:0; padding:0; }
#main-container { background:black; width:800px; }
-->
</style>
</head>
<body>
<center>
<div id="main-container">
Content
</div>
</center>
</body>
</html>
But I am not sure if this is cross-browser compatible, or if its valid xhtml.
The center tag is deprecated since 1998. You need to apply CSS margin 0 auto; on the div. This will set top and bottom margin to 0 and left and right margin to auto which will let the div "auto-center" itself when its width is known/fixed.
See also:
Center a div in CSS, (text-align is not the answer)
remove the center tags, and set this css declaration
#main-container { margin: auto; width:800px }
You can use
#container{
position:relative;
margin: auto;
}
or, if you have a fixed width for your container, lets say 800px you can do something like
#container{
position:relative;
left: -400px;
margin-left: 50%;
}
Use margin: 0 auto;, as stated above:
<style type="text/css">
html, body {
margin: 0;
padding: 0;
}
#main-container {
background: black;
width: 800px;
margin: 0 auto;
}
</style>
And by the way, if you wish to validate as proper XHTML, you need to add type="text/css" to your style elements. In addition, there is almost no need to hide your CSS from old browsers, because almost all browsers nowadays supports CSS.
I would like to have the following layout
+++++++++++++++++++++++
+Header +
+++++++++++++++++++++++
+Nav+ +
+ + +
+ + +
+ + Content +
+ + +
+++++++++++++++++++++++
so basically a two column layout with a header. I've checked many CSS layout generators on the net, but they just produced me a result where the left navbar is as big as the content in it. I can scale it with "height:500px" or whatever, but i want it to be fullsize (from top to bottom of browser window) all the time. Changing the value with "height:100%" does not work.
If you want to try it out yourself: http://guidefordesign.com/css_generator.php and then select full page, two column layout, with header to see what i mean. If you want you can tell me which property i have to adjust in the generated css file to make it work
You can try this. It works on the browsers I tested (Firefox, IE7+8, Opera, Safari, Chrome). Just play around with the percentage units for header and columns.
<!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>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>for stackoverflow</title>
<style>
body, html {
padding : 0px;
margin : 0px;
height : 100%;
}
#wrapper {
width:900px;
height:100%;
margin: 0px;
padding: 0px;
}
#header {
height:10%;
background-color:#930;
width:900px;
}
#nav {
background-color:#999;
width:200px;
height:90%;
float:left;
}
#content {
height:90%;
background-color:#363;
width:700px;
float:left;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="header"></div>
<div id="nav"></div>
<div id="content"></div>
</div>
</body>
You might want to have a look at and get the idea from:
Super Simple Two Column Layout
See the demo here.
A little general answer: Look into CSS frameworks, like http://www.blueprintcss.org/ - these let you define grids.
Here's a sample page: http://www.blueprintcss.org/tests/parts/sample.html
Concerning the height problem, try out this (should give you 100% of browser window height for your div all the time):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test Page</title>
<style type="text/css">
body {
padding: 0px;
}
.Container {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px;
background-color: #123456;
color: black;
}
</style>
</head>
<body>
<div class="Container">
</div>
</body>
</html>
A solution you can try, is to give the content area a background image which is repeated vertically (1px height and width of your page). The left side of that image would have the nav background color, and the rest would be the color of the content background color ...
I have a container div. Width: 80%, margin-left: 10% and margin-right 10%. The problem is, the container is displaying to the left in all the browsers I check. If I change the value of margin-left to 20%, it looks ok.
I will supply code if necessary but is there anything obviously wrong here? Isn't 80 with a margin of 10 on each side correct to center a div?

I tried your setup, and it works just fine.
You should check the spelling and syntax of your CSS, there is probably some error that keeps it from working. In Firefox you can open up the error console and reload your page, and it will tell you about any CSS errors.
You can also use margin-left: auto; margin-right: auto; to center the element.
Here is the code of the page that I used to test the CSS:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="sv" xml:lang="sv">
<head>
<title>Test</title>
<style type="text/css">
div { width: 80%; margin-left: 10%; margin-right: 10%; background: #ccc; }
</style>
</head>
<body>
<div>asdf</div>
</body>
</html>
has the parent element of the div a specified witdh?
Try
width: 100%;
for the parent Element
try set theese:
<html>
<head>
<style>
.container {
position: relative;
margin-left: auto;
margin-right: auto;
width: 80%;
background-color: red;
}
</style>
</head>
<body>
<div class="container">
