title: Correct placement of the buttons in relative layout?
body: <p>I have designed the following layout <a href="http://i61.tinypic.com/33w1oy1.jpg" rel="nofollow noreferrer">http://i61.tinypic.com/33w1oy1.jpg</a></p>
  
  <p>But it looks like this in any device: <a href="http://i60.tinypic.com/zvbxiu.png" rel="nofollow noreferrer">http://i60.tinypic.com/zvbxiu.png</a></p>
  
  <p>Why there is a gap between the inquiry and training buttons.</p>
