How to expand div to cover remaining page height

Sorry, the search returned a ton of results, but nothing that exactly matches my problem. SO seems to be drowned in div-height issues .: - (

I have the following test layout:

<!DOCTYPE html>
<html>
<head>
    <title>Div Test</title>
    <style type="text/css" media="screen">
        body {
            margin:0;
        }
        div {
            width:100%;
        }
        .content {
            position:relative;
            float:none;
            margin-left:auto;
            margin-right:auto;
            display:block;
            width:680px;
        }
        #one {
            height:100px;
            position:relative;
            background-color:#0000FF;
        }
        #two {
            position:relative;
            background-color:#00FF00;
            height:100%;
            min-height:400px;
        }
        #three {
            height:70px;
            background-color:#FF0000;
            bottom:0;
            position:absolute;
        }
        #oneone {
            height:100%;
            background-color:#838383;
        }
        #twotwo {
            height:400px;
            background-color:#EEFF47;
        }
        #threethree {
            height:100%;
            background-color:#400080;
        }
    </style>
</head>
<body>
    <div id="one">
        <div class="content" id="oneone"></div>
    </div>
    <div id="two">
        <div class="content" id="twotwo">Expand this to the bottom.</div>
    </div>
    <div id="three">
        <div class="content" id="threethree"></div>
    </div>
</body>
</html>

I want the divs one and three to stay above and below, the twotwo div must expand in height to accommodate my pagecontent, and expand when the content is greater than the page height, so pushing div three down and scrolls.

Is this possible without JavaScript? If so, what is the CSS solution for this? Thank!

I think this can be done without a script. Check out this code.

<!DOCTYPE html>
<html>
<head>
<title>Div Test</title>
<style type="text/css" media="screen">
    body {
        margin:0;
    }
    div {
        width:100%;
    }
    .content {
        position:relative;
        float:none;
        margin-left:auto;
        margin-right:auto;
        display:block;
        width:680px;
    }
    #one {
        height:100px;
        position:relative;
        background-color:#0000FF;
    }
    #two {
        position:relative;
        background-color:#00FF00;
        /*changed*/
        min-height:400px;
    }
    #three {
        height:70px;
        background-color:#FF0000;
        bottom:0;
        position:relative; /*changed*/
    }
    #oneone {
        height:100%;
        background-color:#838383;
    }
    #twotwo {
        /*changed*/
        min-height:400px;/*changed*/
        background-color:#EEFF47;
    }
    #threethree {
        height:100%;
        background-color:#400080;
    }
</style>
</head>
<body>
<div id="one">
    <div class="content" id="oneone"></div>
</div>
<div id="two">
    <div class="content" id="twotwo">Expand this to the bottom.</div>
</div>
<div id="three">
    <div class="content" id="threethree"></div>
</div>    
</body>
</html>
