I don't think there is a specific limit - any integer will do. Browsers
don't go around counting from 1 to N where N is your z-index. They just
compare z-indexes to see which is greater.
As a point of comparison, Google Maps gives each map marker a z-index in the
range -9000000 to 9000000. (The default z-index for a marker is the marker's
latitude multiplied by -100000.)
