I don't want to center a div, I want the contents of a div to be centered. I would like horizontal and vertical alignment.
Sorry, if this is too easy or whatever, but this is kind of a hassle to get it right.

I am using IE7
If you know the height and width of your image, position it absolutely, set top/left to 50% and margin-top/left to negative half the height/width of your image.
#foo {
position:relative; /* Ensure that this is a positioned parent */
}
#foo img {
width:240px;
height:200px;
position:absolute;
left:50%;
top:50%;
margin-left:-120px;
margin-top:-100px;
}

I know you've said that dont want to center a div but to achieve your requirement in a cross browser way would be easier using a jquery plugin and a fake div that contains your element to be centered.
I have successfully centered almost anything using this very small plugin that can center any block element.
The only other way I know are the answer that you already received from #simshaun & #Prhogz
EDIT: As per comment request
Include the script in your head tag
<script type="text/javascript" src="<%: Url.Content( "~/_assets/js/jquery.center.min.js" )%>"></script>
Now if you have a DIV that you want to center inside your markup simply use it as
$(document).ready(function() {
$("#myDIV").center({ vertical: false });
});
although the following is obsolete, it still works for almost all browsers
<center>
<div>
your html
</div>
</center>
however, visit this link
http://www.110mb.com/forum/vertical-horizontal-alignment-of-image-within-div-t31709.0.html
For horizontal alignment, use text-align:center;
For vertical alignment, see for example the W3 style guide
If you know the inner element's height beforehand,
CSS:
.container {
text-align: center; /* Center horizontally. */
/* For demo only */
border: 1px solid #000;
height: 500px;
margin: 20px;
width: 700px;
}
.container img {
margin-top: -167px;
position: relative;
top: 50%;
}
HTML:<div class="container">
<img src="http://farm6.static.flickr.com/5004/5270561847_7223069d5e.jpg" width="500" height="334" alt="">
</div>

I've been enjoying and having success mocking up webpages with CSS. But then I decided to play with a "fixed menu" and my understanding is now not so clear.
So my brief knowledge make a blank HTML doc and then create a "container" div and place all your further elements within the "parent" container. No problem with this and all has been well with floating elements and such.
But when placing a "fixed" element within my parent div I'm lost as to why the fixed element observes the parent's left margin and ignores it's right margin.
html, body{margin: 0; padding: 0;}
#container
{
margin:0px auto;
width:90%;
height:500px;
background:#A8A8A8;
}
.fixed-menu
{
position: fixed;
height: 50px;
width:100%;
background-color: #00a087;
}
<body>
<div id="container">
<div class="fixed-menu"></div>
</div>
</body>
So with the above the "fixed" block does align with the left margin of the parent container but runs completely to the right edge of the browser page. I have figured out that I can make the fixed block 90% and resolve the issue but I don't understand why. Why would the block not be 90% of the parent "container" block.
I look forward to you knowledge.
Thanks
Update your css like below to achieve your desired result. Inherit your width from the parent instead of using 100%.
.fixed-menu
{
position: fixed;
height: 50px;
width:inherit;
left:auto;
right:auto;
background-color: #00a087;
}
DEMO
as stated by #freestock.tk, a fixed element is "fixed" to the screen viewport.
the width (and height of set in %) is computed relative to the screen viewport.
it looks like it's aligned to left margin of the parent container because you did not positioned it with left or right css properties, it's not constrained by the parent container, it is just at the same horizontal position in this peculiar case.
if you set
left:0;
it will align to the left margin of the viewport and ignore the parent container, this should help you better understand his fixed positioning.
html, body{margin: 0; padding: 0;}
#container
{
margin:0px auto;
width:90%;
height:500px;
background:#A8A8A8;
}
.fixed-menu
{
position: fixed;
left:0;
height: 50px;
width:100%;
background-color: #00a087;
}
<body>
<div id="container">
<div class="fixed-menu"></div>
</div>
</body>
You where almost there, just add to .fixed-menu few css rules more :
.fixed-menu {
left:0;
right:0;
margin:0 auto;
width: 95% // now you can change width and fixed element will be centered always
}
I have two div's side by side. On the left is an image, on the right are inputs.
The image varies depending on what the user uploads.
How can I vertically centre align the image and the inputs? I would like the inputs to appear vertically centre to the image.
Both the img and inputs have their own container:
<div class="img-container">
<div class="data-container">
Fiddle:
http://jsfiddle.net/vbLht/
Remove float:left and try display CSS Rule
.img-container {
width: 50%;
display:inline-block;
vertical-align:middle;
}
.data-container {
width: 50%;
display:inline-block;
vertical-align:middle;
}
Fiddle
Note: You need to set <!-- --> to your mark-up after inline divs as css inline rule will leave white-space between 2 elements, Though this an awkward way but if you don't want to write that crack then you've to adjust width.
Or
Set your li style to display:table with the above CSS Code
li{
display:table; /*remove float*/
}
.img-container {
width: 50%;
display:inline-block;
vertical-align:middle;
}
.data-container {
width: 50%;
display:inline-block;
vertical-align:middle;
}
Hope this is clear :)
Flexbox makes this very easy.
Just wrap the child elements you want to vertically center in a wrapper div with:
.wpr {
display:flex;
align-items: center; /* align vertical */
}
FIDDLE
Browser support is good in modern browsers - caniuse..
but if CSS3 isn't an option, the display:table approach (As mentioned in the other answer) is fine.
I know it's a super-basic question, but I'm not able to find a solution. I have 2 div and I would like to display them as blocks (one below the other) without having 100% width. Here's my code.
HTML
<div id="container">
<div class="test">one</div>
<div class="test">two</div>
</div>
CSS
.test {
display:inline-block;
clear: both;
border:1px solid;
}
#container {
clear:both;
text-align:center;
}
Unfortunately this answer doesn't fit to me, since I need to center blocks horizontally (so float cannot be applied in my case). Here's the fiddle. Thanks in advance.
to center them on top of each other without taking 100% width and still use margin:auto; use : display:table;
.test {
display:table;
margin:auto;
border:solid;/* to see it */
}
You can specify the width of the divs, change display to block, and use margin: 0 auto to center them.
JSFiddle
You can also center the div by adding 50% left offset, and then negative margin in amount to half width of the div. I do not know how much is this applicable to your case, but here is an example:
.test {
position: relative;
border:1px solid;
width: 300px;
left: 50%;
margin-left: -150px;
}
You can see it in action here: http://jsfiddle.net/b8LuQ/7/
display:inline-block; is not allow the second line. Therefore I removed it and define width for both div test one two you can resize it and margin:auto is align center the both div in container here is an example
So yet another question about vertically aligning an image within a div, but I think mine is different than the others I've found on here. I can't seem to find a solution that works for my situation.
I have a DIV that is 100% width (to it's container, which is floating left and has a set pixel width) and has a set pixel height. I have an image inside that I am positioning absolute to get it to the background of content within the DIV. The image is fluid with a width of 100%.
All works well, but I want to get the image to vertically align to the middle of the container and height is unknown.
Here is some sample code that shows what I'm trying to do:
<div class="container">
<div class="image-wrapper">
<img src="http://farm5.staticflickr.com/4111/4968056789_d872094672_o.jpg"
width="100%" />
</div>
<p>Some text</p>
</div>
And some sample CSS:
.container {
width:100%;
margin-top:10px;
height:100px;
overflow:hidden;
}
.image-wrapper {
position: relative;
}
.image-wrapper > img {
position: absolute;
z-index: -1;
}
p {
text-align: center;
padding-top: 10px;
color:#fff;
font-weight: bold;
}
But the flower should show up with it's center visible within the container div.
Any thoughts? I'm trying to avoid any Javascript sizing (the outer container, not shown in this sample, is already being sized). I'm not opposed to more DIVs, tables.. whatever you got!
A jsFiddle to demo this:

Why not go for the background-image property? That allows vertical centering...

Assuming you want to only scale the image down and not stretch it beyond its native resolution this should do the trick. A little bit of jQuery is involved but it's minimal. Essentially, this adjusts the top-margin of the IMG on the window.resize event.
HTML
<div id="container">
<img id="image" src="image.jpg"> <!-- native size is 480x300 -->
</div>
CSS
#container {
margin: auto;
width: 80%;
height: 300px;
border: 1px solid gray;
}
#image {
display: block;
width: 100%;
max-width: 480px;
margin: auto;
}
jQuery
function adjustImage() {
$("#image").css('margin-top', ($("#container").height() - $("#image").height()) / 2);
}
$(window).load(function() {
adjustImage();
$(window).resize(function() {
adjustImage();
});
});
If I get what you need I would suggest setting the background image via css, then you can set the position correctly etc.
.container {
width:100%;
margin-top:10px;
background-image:url("http://farm5.staticflickr.com/4111/4968056789_d872094672_o.jpg");
background-repeat:no-repeat;
background-position:left center;
height:100px;
overflow:hidden;
}

Hi I have a container which has a width of 1150px. Now I have this other mainmenu, with width: 100% that I want to place inside the container. But then ofcourse it only get 100%(1150px) but I want it full width from side to side, so it should ignore the setted width only for .mainmenu
I tried position: absolute which made it all wrong and weird
#mainmenu
{
height: 37px;
width: 100%;
margin: 0px auto;
background-image: url(../images/mainmenu_bg5.jpg);
}
Why is the menu in the container in the first place? If you want the menu to span the full width yet the contents of the container are only 1150px I think it is by definition not right to put the menu in the container. Consider restructuring your document. This is an example, I do not have your full code:
<body>
<div id="page">
<div id="header" style="background:Blue;">
header header header
</div>
<div id="mainmenu" style="background:Green;">
menu menu menu menu
</div>
<div id="container" style="width:1150px;margin:auto;background:Red;">
container container container
</div>
</div>
</body>
And if you want the contents of the header and menu to span no farther than 1150px which I think is what you want then consider this:
<head>
<style type="text/css">
.pagewidth {
width: 1150px;
margin: auto;
}
</style>
</head>
<body>
<div id="page">
<div id="header" style="background:Blue;">
<div class="pagewidth">
header header header
</div>
</div>
<div id="mainmenu" style="background:Green;">
<div class="pagewidth">
menu menu menu menu
</div>
</div>
<div id="container" class="pagewidth" style="background:Red;">
container container container
</div>
</div>
</body>
If your container is fixed-width, but you want a menu which has a background at full page-width, then you can have the menu background as a positioned background of html, and maintain the same HTML code. This will make the menu's background "bar" cover the whole page width.
Example of this method: http://templates.arcsin.se/demo/freshmade-software-website-template/index.html
How to do this: use positioned backgrounds:
http://www.w3schools.com/css/pr_background-position.asp
css is below, but sometime it depend from the content inside:
#mainmenu
{
height: 37px;
width: 100%;
margin: 0px;
position: relative;
background-image: url(../images/mainmenu_bg5.jpg);
}
This is a jQuery solution:
$('#mainmenu').width() == $('#container').width();
To get a background image to simulate the menubar spanning the entire width of the page you need to apply the #mainmenu background to the body or a container div like so:
body {
background: url(YOURIMAGE) repeat-x left 64px;
}
The 64px needs to be how far the #mainmenu is from the top.
If the body already has a background image then you will need another div just inside the body containing everything else. If you have no control over the HTML then using javascript to insert a div that will either wrap all the content or get rendered behind it (using position and z-index.)
position:absolute is the best way to get this while keeping the background in #mainmenu. In fact, it's the only one I can think of off the top of my head. Without javascript, of course. Everything else will require changing HTML or moving the background property to a different place.
#mainmenu
{
position:absolute;
left:0;top:??px;
width:100%;
height:37px;
background-image: url(../images/mainmenu_bg5.jpg);
}
Because #mainmenu's width:100% then will become 100% of the viewport rather than the containing block. (Unless a parent is position:relative or overflow:hidden)
So when you say it "got all weird", I assume that's because of other things on the page. Both absolute and float take items out of the normal document flow. So things below the menu can & will end up underneath it.
#mainmenu
{
position:absolute;
left:0;top:??px;
width:100%;
height:37px;
background-image: url(../images/mainmenu_bg5.jpg);
}
#mainmenu + *
{
padding-top:37px;
}
/* Exact selector not recommended due to poor browser support */
The solution to that is, basically, applying 37px of margin or padding to the first thing after #mainmenu. You'll also be unable to center absolutely positioned elements using margin:0 auto, but if you want it spanning the full width of the viewport, that shouldn't be a concern...If you want to center the live sections of the menu, of course, you'll need some sort of descendant to center:
#mainmenu
{
position:absolute;
left:0;top:??px;
width:100%;
height:37px;
background-image: url(../images/mainmenu_bg5.jpg);
}
#mainmenu > *
{
margin:0 auto;
}
/* Exact selector not recommended due to poor browser support */
/* & more properties needed if descendant is list with floated <li>s */
#mainmenu + *
{
padding-top:37px;
}
/* Exact selector not recommended due to poor browser support */
But there are lots of things you'll see change in relation to other things on the page with position:absolute. So to troubleshoot that I really need to know more about the other things on the page.
You may find another solution, but if you don't -- post a page I can look at & I may be able to help you with the weirdness you experienced with absolute positioning. That is, if it will work with this particular layout.
