title: Should Objects get their own Z-index?
body: <p>So I am converting some old code, and in it I have found each Textbox, label and Dropdown was given its own unique Z-Index.  Now, I thought this was pretty pointess (we were not hiding any objects, which is usually when I use Z-Indexes) but when I was talking with a coworker, they said everything should have its own Z-Index (to meet HTML standards).</p>
  
  <p>I tried Googling, but most of the links I found were just about overlapping.  Is this an HTML standard?  Have I been missing this standard for the last 10 years and just lucked out enough to never be annoyed by it?</p>
  
  <p>Thanks</p>
