114996 - Negative z-index value causes blank DIV display

Status: RESOLVED DUPLICATE of bug 78087

(Core :: CSS Parsing and Computation, defect)

Description

[Katsuhiko Momoi]

** Observed with 2001-12-11 Win32 trunk build **

The above page has 2 DIV's on the page (id=Layer1" and id="Layer2").
For styling, it uses z-index values of -2 and -1. These nagative
values seem to cause a display problem with current build resulting in
non-display of these DIV sectinons. 
CSS2 specs simply say that z-index can take "Integer" values. And
"Integer" can have "+" or "-" prefixes, i.e. it can be negative or
possitive.  This seems to be a bug in Mozilla. 

I'll attach 2 test pages below.

Neither Comm 4.x nor IE5.5 has this problem.

Comment 2

Attachment: The page at above URL with z-index values corrected to 0 and 1 from -2 and -1.

You can see the left and right sections of the page with the corrections 
of the 2 z-index values to positive integers keeping the relative 
positioning intact.

Attachment: The original problem page. Uploaded here in case the original page becomes unavailable.

Look at the z-index values of the original page for the 2 DIVs. -2 and -1.
