title: z-index isn't applied
body: <p>First off, please let me say I'm pretty new to CSS. Still lots to learn! I'm working on a site at <a href="https://web.archive.org/web/20130709112702/http://www.thesweet-spot.com/test77" rel="nofollow noreferrer">https://web.archive.org/web/20130709112702/http://www.thesweet-spot.com/test77</a></p>
  
  <p>Everything is working great, EXCEPT that the main content box is being placed under the fixed-position logo instead of over it, even though the z-index on the logo is lower than the z-index on the content box. What can you geniuses tell me?</p>
