Center a DIV horizontally and vertically

Is there a way to CENTER A DIV vertically and horizontally but, and that is important, that the content will not be cut when the window is smaller than the content The div must have a background color and a width and hight.

I have always centered divs with the absolute positioning and negative margins like in the example provided. But it has the problem that it cuts the content on top. Is there a method to center the div .content without this problem?

I have the example here to play: http://jsbin.com/iquviq/1/edit

CSS:

body { margin: 0px; }

.background {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
	background-color: yellow;
}

/* 
is there a better way than the absolute positioning and negative margin to center the div .content: div with background color a width and a hight?: 
*/ 


.content {
    width: 200px;
    height: 600px;
    background-color: blue;
	
    position:absolute;
    top:50%;
    left:50%;
    margin-left:-100px;/* half width*/
    margin-top:-300px;/* half height*/
}

HTML:

<div class="background">
    <div class="content"> some text </div>
</div>

My question is not duplicate of "How to center an element horizontally and vertically? " 1- My question was asked before. (just check dates). 2- My question ask very clearly and in black as condition: "the content will not be cut when the window is smaller than the content"

For modern browsers

When you have that luxury. There's flexbox too, but that's not broadly supported at the time of this writing.

HTML:

<div class="content">This works with any content</div>

CSS:

.content {
  position: absolute;
  left: 50%;
  top: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

Tinker with it further on Codepen or on JSBin

For older browser support, look elsewhere in this thread.

After trying a lot of things I find a way that works. I share it here if it is useful to anyone. You can see it here working: http://jsbin.com/iquviq/30/edit

.content {
        width: 200px;
        height: 600px;
        background-color: blue;
        position: absolute; /*Can also be `fixed`*/
        left: 0;
        right: 0;
        top: 0;
        bottom: 0;
        margin: auto;
        /*Solves a problem in which the content is being cut when the div is smaller than its' wrapper:*/
        max-width: 100%;
        max-height: 100%;
        overflow: auto;
}

Here's a demo: http://www.w3.org/Style/Examples/007/center-example

A method (JSFiddle example)

CSS:

html, body {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}
#content {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}

HTML:

<div id="content">
    Content goes here
</div>

Another method (JSFiddle example)

CSS

body, html, #wrapper {
    width: 100%;
    height: 100%
}
#wrapper {
    display: table
}
#main {
    display: table-cell;
    vertical-align: middle;
    text-align:center
}

HTML

<div id="wrapper">
<div id="main">
    Content goes here
</div>
</div>

The legitimate way to do that irrespective of size of the div for any browser size is :

   div{
    margin:auto;
    height: 200px;
    width: 200px;
    position:fixed;
    top:0;
    bottom:0;
    left:0;
    right:0;
    background:red;
   }

Live Code

You can compare different methods very well explained on this page: http://blog.themeforest.net/tutorials/vertical-centering-with-css/

The method they recommend is adding a empty floating element before the content you cant centered, and clearing it. It doesn't have the downside you mentioned.

I forked your JSBin to apply it : http://jsbin.com/iquviq/7/edit

HTML

<div id="floater">
</div>

<div id="content">
  Content here
</div>

CSS

#floater {
  float: left; 
  height: 50%; 
  margin-bottom: -300px;
}

#content {
  clear: both; 
  width: 200px;
  height: 600px;
  position: relative; 
  margin: auto;
}

I do not believe there is a way to do this strictly with CSS. The reason is your "important" qualifier to the question: forcing the parent element to expand with the contents of its child.

My guess is that you will have to use some bits of JavaScript to find the height of the child, and make adjustments.

So, with this HTML:

<div class="parentElement">  
  <div class="childElement">  
    ...Some Contents...  
  </div>  
</div>  

This CSS:

.parentElement {

position:relative;
width:960px;
}
.childElement {
position:absolute;
top:50%;
left:50%;
}

This jQuery might be useful:

$('.childElement').each(function(){
  // determine the real dimensions of the element: http://api.jquery.com/outerWidth/
  var x = $(this).outerWidth();
  var y = $(this).outerHeight();
  // adjust parent dimensions to fit child
  if($(this).parent().height() < y) {
    $(this).parent().css({height: y + 'px'});
  }
  // offset the child element using negative margins to "center" in both axes
  $(this).css({marginTop: 0-(y/2)+'px', marginLeft: 0-(x/2)+'px'});
});

Remember to load the jQ properly, either in the body below the affected elements, or in the head inside of $(document).ready(...).

You want to set style

margin: auto;

And remove the positioning styles (top, left, position)

I know this will center horrizontaly but I'm not sure about vertical!
