Vertically Center Div When Body Height: 100% Without Absolute Pos

vertically center div when body height: 100% without absolute pos

You can use display:table and display:table-cell:

html, body {    width: 100%;    height: 100%;}
body{    margin: 0;    display: table}
body>div {    display: table-cell;     text-align: center; /* horizontal */    vertical-align: middle; /* vertical */}

<div>    <img src="http://paw.princeton.edu/issues/2012/07/11/pages/6994/C-beer.jpg" /></div>

Vertically center text in a 100% height div?

This answer is no longer the best answer ... see the flexbox answer below instead!

To get it perfectly centered (as mentioned in david's answer) you need to add a negative top margin. If you know (or force) there to only be a single line of text, you can use:

margin-top: -0.5em;

for example:

http://jsfiddle.net/45MHk/623/

//CSS:
html, body, div {
    height: 100%;
}

#parent
{
    position:relative;
    border: 1px solid black;
}

#child
{
    position: absolute;
    top: 50%;
    /* adjust top up half the height of a single line */
    margin-top: -0.5em;
    /* force content to always be a single line */
    overflow: hidden;
    white-space: nowrap;
    width: 100%;
    text-overflow: ellipsis;
}

//HTML:
<div id="parent">
    <div id="child">Text that is suppose to be centered</div>
</div>​

The originally accepted answer will not vertically center on the middle of the text (it centers based on the top of the text). So, if you parent is not very tall, it will not look centered at all, for example:

http://jsfiddle.net/45MHk/

//CSS:
#parent
{
    position:relative;
    height: 3em;
    border: 1px solid black;
}

#child
{
    position: absolute;
    top: 50%;
}​ 

//HTML:
<div id="parent">
    <div id="child">Text that is suppose to be centered</div>
</div>​

Vertically centering a div in body?

See this edited version of your jsFiddle.

Basically, just wrap your content in <div class = "main"><div class = "wrapper"></div></div>, and add the following CSS:

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

vertical-align in div with height 100%

Live Demo

I just made a jsFiddle showing my suggestion to a solution. Here I take into account that you want two <div>s filling 50% of the width each, 100% height, and that you want the content to be vertically aligned in the middle. Here is the simplified working solution with source code.

HTML

<div id="outer">
    <div id="table-container">
        <div id="table-cell">
            This content is vertically centered.
        </div>
    </div>
</div>

CSS

#outer {
    position:absolute;
    top:0;
    left:0;
    width:50%;
    height:100%;
}

#table-container {
    height:100%;
    width:100%;
    display:table;
}

#table-cell {
    vertical-align:middle;
    height:100%;
    display:table-cell;
    border:1px solid #000;
}

For reference, I used this tutorial.

How to vertically center content with variable height within a div?

Just add

position: relative;
top: 50%;
transform: translateY(-50%);

to the inner div.

What it does is moving the inner div's top border to the half height of the outer div (top: 50%;) and then the inner div up by half its height (transform: translateY(-50%)). This will work with position: absolute or relative.

Keep in mind that transform and translate have vendor prefixes which are not included for simplicity.
