Is there a standard or de-facto standard for the z-index on expandable banner ads when they are in their expanded state? I am building an expandable banner and I will have no control over where it will be placed, so I need to know what I should set the z-index to set it to so that the banner above any normal page content but under any menus etc.

Set it to one billion trillion.
There is no real standard.
The reason for this is because if you are arbitarily plaing the ad on a page where you have no idea the css of the current page, then you cannot possibly know what the max z-index is on the page in order to trump it.

Actually, I think that would overflow on some browsers. – Digital Plane Sep 01 '11 at 15:58

The thing is that I don't want to trump it because there is a requirement that any menus appear above the banner, even in the expanded state. It doesn't matter, I just gave the website owners the ability to set the z-index to what they feel is appropriate for their page. – DanielM Sep 13 '11 at 13:38
