Hi, If your trying to achieve the effect that 21 degrees make, you should take a look that they've used a full body background for both the main and navigation, second, they have used another footer background image to achieve the ending footer.
Check it using firefox and rightclick on the maincontent - view background, probably you could get the idea and concept on how they implment the css. :) or follow this link: http://www.21degrees.com.au/style/default/img/banner.jpg By the way, I've checked their css document and I found no CSS Z-Index thing. ****************************************************** The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list & getting help ******************************************************
