title: Superimposed Label on the header
body: <p>I have a little mistake.
  <a href="https://i.stack.imgur.com/odixd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/odixd.png" alt="enter image description here"></a></p>
  
  <p>As you can see ont the picture, the color picker and the checkbox are superimposed on the header. And i want it to be hidden by the header.</p>
  
  <p>I don't understand why, and why the other label (text label) are hidden by the header.</p>
  
  <p>For both visible element I use webkit for somes animations, maybe it can come from there.</p>
  
  <p>Maybe someone has already solved the problem...</p>
  
  <p>Thank you.</p>
