In my app, I have a temporary div that is shown each time the app is saved (see markup below). I'm using jQuery 1.4.2 and would like to know the command that will fade this div off the screen after 3 seconds...

<script src="../wp-content/themes/mytheme/jquery-1.4.2.min.js" type="text/javascript"></script>
if ($_REQUEST['saved']) echo '<div id="message" class="updated fade"><p>'.$themename.' settings saved.</strong></p></div>';
