ドキュメントには、cssについては特に記述がありませんがありますね

https://developers.google.com/speed/libraries/devguide

こんな感じで使えます

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/hot-sneaks/jquery-ui.css" type="text/css" media="all" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/jquery-ui.min.js"></script>
