title: Question on z-index on IE8 browser
body: <p>Using Developer toolbar  on IE8 , on one page i see that the z-index  for a DIV shows as "auto",  I went from this element  to its parent hierarchy checking if some element has actually defined this attribute(z index) but I did  not see any element that has the css style attribute z-index defined/set.</p>
  
  <p>I created a sample page where I did the same thing and it shows me the z-index as 0.</p>
  
  <p>I have not defined my div or any other element to have zindex attribute but still it shows me the z-index as 0.</p>
  
  <p>I am trying to find out why would I get the ZIndex as 0 on one page and Z-Index as "auto" on other when  it has not been defined in either of the pages.
  Here is the sample of the css for that div.</p>
  
  <pre><code>.mydiv
  {
  position:absolute;
  overflow-x:hidden;
  overflow-y:auto;
  }
  </code></pre>
  
  <p>thanks</p>
