Hi all! I'm trying hard not to use tables, but can't figure out how to do this w/ box modeling. I would like a div that is auto hight so that it stretches to accommodate the contents. Inside that div I need 3 divs, left column (auto height), right column (auto height), and a divider in the middle which is like a middle column. That middle divider needs to be 100% height of the parent div so that it stretches w/ it. Kind of like a table, you know.

I can't figure out how to do this. Everything I find on google tells me that for a div to be 100% height, height needs to be specified, either in percent or pixels on the parent div and all the way up to body/html. But I can't have that, the parent div needs to stretch and can't have a minimum height.

Here's my mini-example code. As you can see the middle/divider column's got a non-existant height.

Code:

<html>
    <head>
        <title>Test Div Stretch</title>
        <style type="text/css">
            #clearBoth {clear: both; visibility: hidden;}
            .container {border: 1px blue solid;}
            .col { float:left; border: 1px solid red; width: 300px;}
            .divider { width: 3px; height: 100%; background: green;}
        </style>
    </head>
    <body>
        <div class="container">
            <div id="leftCol" class="col">Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.

            <div id="midCol" class="col divider"></div>
            <div id="rightCol" class="col">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed</div>
            <div id="clearBoth"></div>
        </div>
    </body>
</html>
I'm almost ready to resort to tables.
Any ideas?

Thanks!
