If you want this on one page paste the code below right into your page. If you want it on every page paste it in to the custom header markup.
<style type="text/css">
div#shopbanner{width:942px;height:250px;left:-200px;
top:-400px;position:relative; z-index:1000;}
</style><div id="shopbanner"><iframe src="http://mydomain.com/fonts/font.html" width="500px"></iframe></div>
I used this method for the custom font. I added the font to a html page and linked to that in the iframe.
