A bit about z-index
The z-index CSS property changes the stacking order of positioned elements (those with the position property set to values other than static) and their descendants or elements within flex and grid.
Key points about z-index:
- Not inherited.
- For positioned elements it defines the stacking level within the current stacking context.
- Determines whether a local stacking context is established
Minimum and maximum value of z-index
The z-index can take any value within the range of -2147483648 to 2147483647 in most browsers. These values correspond to the range of integers representable in 32-bit systems. In other words the minimum value for z-index is -2147483648 and the maximum is 2147483647.
Attempting to set a value beyond this range will cause z-index to be set to either the minimum or maximum value depending on the context.
