title: Selenium - Check if an element is under another one
body: <p>I'm using Selenium to do Java test.
  I know that i can check if an element is enable or displayed with this :</p>
  
  <pre><code> isDisplayed
   isEnabled
  </code></pre>
  
  <p>Is it possible to check if an element is not visible, in the case that this element is under another ? For example, if a div is under another one.
  With that i want to check GUI element. For example if a button move under element, etc ... </p>
  
  <p>Any ideas ? </p>
  
  <p>thanks for helping _</p>
