[Webpro] CSS Quirk or Newbie Coder?

[Jeanne]

Hi All,
 
FWIW, here's what I did with my first CSS layout that many of you graciously
helped along:

For my next feat of CSS (and it does feel like a feat to me, although I'm
starting to get the hang of it!), I'm trying to recreate the
www.record-eagle.com home page with CSS. Here's what I've got so far:

My CSS file is here: http://www.tech-ease.net/portfolio/record-eagle/r-e.css
 
My probelm is the gap that appears in IE6 between the navigation (#topnav)
and the row of divs below it, specifically the #masthead div. NS 7.1 (as
well as my preview in Dreamweaver) seems to render this correctly. 
 
Can anyone shed some light on this quirk for me or point out where my code
goes wrong?
 
Thanks much!
