Htmleditorextender Set default font family

How would you set the default font family type to Georgia of an html editor extender.  The html editor extender default font type is Arial when page loads but when the page loads I want it to set it to Georgia automatically.

I saw one post to set it through javascript for font size.  

<script type='text/javascript'>
     setTimeout(function(){ document.getElementById('<%= YourHtmlEditorExtender.ClientID %>').getElementsByTagName('select')[1].value = 3; }, 1000);</script>

How would you do this for font family or do it somehow with css?

Thanks
