I've got a quick question. I need to make a div that holds a swf file (with a transparent background) of the site's navigation. This navigation has a drop down menu, so it's supposed to cover part of the site. How do I overlap a div, centered on the page? Right now I've got: margin-left: auto;
    margin-right: auto;
    width:111px;
    height:72px;
    z-index:1;

to keep it centered, but I can't get it to overlap (by about 100 pixels).

I would like to see more of the page to try to figure this out, I will try to reproduce it but hard without the exact flash file. One thing I am thinking of is to use a layer to encompass the flash file navigation instead. A simple table might work also. Why are you using div, are you using CSS for other parts of the div? Don't get me wrong I am all for using div wherever possible for the functionality but you may need a work around.

You need to add position: relative; or position: absolute; to get layering.

Rich
