I'm trying to append a css file to an iframe that is created on a page from a global script. I can access part of it, but for some reason I can't append to the head. It's not throwing errors either, which is frustrating.

<script type="text/javascript">
$(document).ready(function() {                   
  $('#outline_text_ifr')
    .contents()
    .find('head')
    .append('<link type="text/css" rel="stylesheet" href="/include/outline.css" media="all" />');
});
</script>
