title: jquery impromptu overriding default width height of impromptu css for one instance
body: <p>Does impromptu allow configuring the width/height of the popup message section? I checked the documentation at <a href="http://trentrichardson.com/Impromptu/index.php" rel="nofollow">http://trentrichardson.com/Impromptu/index.php</a>, but do not see any parameter which allows that. </p>
  
  <p>I am using impromptu version 3.1. I have to display an over-sized prompt, around 900px by 700px (width by height). The default width/height of impromptu is not enough for one of my popups and  so I need to override it for this particular case. Other popups of my site have normal content and so should be of normal size. </p>
  
  <p>In the impromptu css file, there is - </p>
  
  <pre><code>div.jqi {width:400px;}
  </code></pre>
  
  <p>So, the width of the message section is fixed. </p>
  
  <p>I just wanted to make sure about this before making any changes myself.</p>
  
  <p>Thanks</p>
