title: Change div's height and set absolute position break Bootstrap responsiveness
body: <p><strong>Bootstrap 3.x</strong> framework and <strong>jQuery 2.x</strong> library are been used.</p>
  
  <p>I have four divs in three different rows. I am using jQuery to change the div height when mouse hover. </p>
  
  <p>Use of z-index and absolute position break Bootstrap responsivness.</p>
  
  <p>Using z-index and absolute position with .col-xs-* can provide a working solution. However, the result is not mobile friendly.</p>
