So I downloaded a jQuery UI Theme and link it, but it looks nothing like the them on the site. The buttons are huge and so is the text.

<link rel="stylesheet" type="text/css" href="/css/trontastic/jquery-ui-1.8.2.custom.css">
$('#Delete').dialog({
                modal: true,
                autoOpen: false,
                title: "Delete?",
                buttons: {
                    "Yes": function(){
                        $(this).dialog('close');
                        $('li#'+$id).remove();
                        $('.nav').sortUpdate();
                    },
                    "No":function(){
                        $(this).dialog('close');
                    }
                },
                draggable: false,
                resizable: false
    });

Am I missing something or is there addition css that I have to handcode? Thanks
