PhoneGap won't load the Google font or the jQuery lib. Here is the code
<link href='http://fonts.googleapis.com/css?family=Source+Sans+Pro:200' rel='stylesheet' type='text/css'>
and here is the HTML
<span style="font-size:24px;">Featured Items</span>
You don't specify the font-family
anywhere.
<span style="font-family:'Source Sans Pro',sans-serif; font-size:24px;">Featured Items</span>
Note that inline styles should be avoided when possible.
