What is the maximum and minimum value for z-index?

Navigation
8

I was discussing with some friends about putting 99999 on z-index to ensure that the element has the highest degree of overlapping priority over another element.

But when I thought about it, I had a little curiosity:

  • What is the maximum value for z-index ?
  • What is the minimum value for z-index , since it supports negative values?
