Editing css within generated iframe
===

I have a site build in joomla, which is using a calendar component (jevents) which generates an iframe in which users can edit an event on their calendar. I need apply css to the body of this iframe, however it linksthe css to the main template style sheet, so if I apply changes changes to that, it effects my whole site. 

I've tried numerous edits in firebug, but the only one that seems to work is styling the iframe in-line - however, I can't locate the proper file/line of code where that is. 

Here's a screenshot. Any suggestions?
