vertical-align in div with height 100% [duplicate]

Question

Here's my situation: I'm trying to make a page with two DIVsfilling whole page (height 100%, width 50% each). Also, the content in the DIVs is to be vertically aligned to middle.

Is there an easy way to achieve this without hacks or javascript?

I've tried body,html{height:100%;} .mydiv {display:table-cell;height:100%;vertical-align-middle}

but that doesn't work...and with that code, i have to specify width in pixels instead of percentage

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;
}
