title: jquery blockui positioning
body: <p>I'm using blockui to throw some forms up on my site but for some reason the blockui element is positioned about 20-30 pixels from the bottom of the screen. I tried, per the docs <a href="http://jquery.malsup.com/block/#options" rel="nofollow noreferrer">(jquery blockui options for v2)</a> to reposition it using this code: </p>
  
  <pre><code> $.blockUI({css: {top : '10px'}});
  </code></pre>
  
  <p>But that just yawned at me in a universe mocking kind of way and did nothing. The default, again, per the docs, is top : 40%. I don't want to wipe out all the blockui css, just reset the top positioning.</p>
