title: z-index not working for fixed element
body: <p>I was working on my code when I stumbled upon this fun fact: </p>
  
  <p><em><code>z-index</code> doesn't work for a fixed element and, therefore, fixed elements will always be in front.</em></p>
  
  <p>Is there a way to place a non-fixed element in front of a fixed element?</p>
  
  <p>Thanks. </p>
