title: How to make one div covering another div in different rows
body: <p><strong>Bootstrap</strong> framework and <strong>jQuery</strong> library are been used.</p>
  
  <p>I have multiple <code>div</code>s in two different <code>row</code>s. I am using jQuery to change the div height in first row when mouse hover. Use of <strong>z-index</strong> and <strong>absolute position</strong> break Bootstrap responsivness.</p>
  
  <p>Using <strong>z-index</strong> and <strong>absolute position</strong> with <code>.col-xs-*</code> can provide a working solution. However, the result is not mobile friendly.</p>
  
  <h3>The Current Situation</h3>
  
  <p>Both <code>div</code> <code>.site-box-id-01</code> and <code>.site-row-id-01</code> 's height change at the same time.</p>

  <h3>The Desired Result</h3>
  
  <p>Instead of changing the entire <code>row</code>'s height, I would like the first <code>div</code> to cover the second one after height changed. How should I implement this in Bootstrap without break responsiveness.</p>
