So I've done some google'ing and I couldn't find a good answer to this.
I use the following code to allow my users to post a status update to their fb:
<html>
<head>
  <title>My Great Website</title>
</head>
<body>
  <div id="fb-root"></div>
  <script src="http://connect.facebook.net/en_US/all.js">
  </script>
  <script>
     FB.init({ 
        appId:'**', cookie:true, 
        status:true, xfbml:true 
     });
     FB.ui({ method: 'feed', 
        message: 'Facebook for Websites is super-cool'});
  </script>
 </body>
Code works fine, however I want to get rid of that horrible looking border and set the width. I heard this isn't possible because of "origin policy" but is it possible to be done with Javascript? Or, can I mimic the plugin above with my own custom script that will still post to FB but I will have more control over it?
