[jQuery] DIV position

[jQuery] DIV position


Is there any way to set the z-index of the div?
I have series of hidden DIVs (in each row of table and clicking any of
those would pop-up a information guide)
Here is my code:
function showProfile(id) {
$('#profile_' + id).show("slow", hideAllProfile
(id));
}
function hideAllProfile(id) {
$(".profilePopup:not(#profile_" + id + ")").hide();
}
This works fine for me on IE browsers. However putting my DIV behind
the table cell on other browsers.
Even setting z-index for the DIV is not working in this case.
Please help!
Thanks,
Paresh
