What is the ultimate goal here?

If you want to have an element hold to the bottom of the screen no matter what and sit on top of any other content, you would use position:fixed...

#bottom_nav {

     width:100%;

     position:fixed;

     bottom:0px;

     text-align:center;

     z-index:9999;

}

Then in your html...

<div id="bottom_nav">Home | About | Contact | Portfolio</div>

    But position:fixed won't center.  Neither will position:absolute.

    Here's the code I mentioned. It uses vh units, so old browsers dislike it, but if you don't care about them (I don't) and you don't plan to go past 600 pixels in height for your content (right now it's set to 400 min-height for both middle ids) this should work...

    <!doctype html>

    <html>

    <head>

    <meta charset="utf-8">

    <title>Test with VH units</title>

    <style>

    body {

        margin:0;

    }

    #topone {

        width:100%;

        height:9vh;

        min-height:50px;

        background-color:gray;

    }

    #middleone {

        width:900px;

        margin:0 auto;

        height:81vh;

        min-height:400px;

    }

    #middle_content {

        min-height:400px;

        background-color:red;

        overflow:hidden;

    }

    #bottomone {

        margin-top:10px;

        margin-top:1vh;

        height:9vh;

        min-height:50px;

        width:100%;

        background-color: gray;

    }

    #topinfo, #bottominfo {

        width: 900px;

        margin: 0 auto;

    }

    </style>

    <!--[if lt IE 9]>

    <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>

    <![endif]-->

    </head>

    <body>

    <div id="topone">

      <div id="topinfo">you can add another div here with the same width as the middleone and margin:0 auto to center it at the same rate as #middleone</div>

    </div>

    <div id="middleone">

        <div id="middle_content">

          Your main content here

        </div>

    </div>

    <div id="bottomone">

      <div id="bottominfo">you can add another div here with the same width as the middleone and margin:0 auto to center it at the same rate as #middleone</div>

    </div>

    </body>

    </html>


    Thank you very much Jon! That vh units really helpful! Just 1 more question, there is a gap between the bottom div and the browser window, if the browser window size is larger, that gap is getting larger as well, how to remove that gap?
