How to display value in jQueryUI ProgressBar?


I've set up a simple jQuery UI ProgressBar:
<script type="text/javascript">
            $(function() {
                $("#progressbar").progressbar({
                    value: 35
                });
            });
            </script>
<div id="progressbar"> </div>
Among other things, I'd like to display some text in the progress-bar
(for starters, I'd just use the "value").
I can't seem to get this to work.
Bonus Question: How do I format the displayed text (e.g. color,
alignment)?
