title: Jquery + Css Drag and Drop offset issue
body: <p>UPDATE: I have updated the jsfiddle to be more clear.  To clarify the issue.  When a tile is dragged from the bottom row and dropped in the top row it causes the droppable div to offset down from the other divs.  When all three divs are filled they are once again inline.  What is causing the offset of the divs when only one or two divs are filled?</p>
  
  <p>I am learning jquery drag and drop now. </p>
  
  <blockquote>
    <p>The problem is that when I drop into my div it is creating an <code>offset</code>
    in the <code>droppable divs</code>.</p>

  <p>You can see the issue in the jsfiddle I have created, link below. I am a beginner at jquery and drag and drop so please keep that in mind if my code is butchered.</p>
