Oh, wait. I see how to do it with tables:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html>

        <head>

                <title>

                        table test

                </title>

                <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

                <style type="text/css">

                        html,body {

                                text-align: center;

                                margin: 0px;

                                padding: 0px;

                                height: 100%;

                        }

                </style>

        </head>

        <body>

                <table border="1" style="height: 100%; width: 100%">

                <tr style="height: 60px"><td>top</td></tr>

                <tr style="height: 100%"><td>bottom</td></tr>

                </table>

        </body>

</html>
I'd forgotten to give the table a style height of 100% as well as the other elements.
