CSS information

Remarks

Positive z-index values are positioned above a negative (or lesser value) z-index. Two objects with the same z-index are stacked according to source order. A positive value positions the element above text that has no defined z-index, and a negative value positions it below. Set this parameter to NULL to remove the attribute.

The z-index property only applies to objects that have the position property set to relative or absolute.

The property does not apply to windowed controls, such as select objects.

Input from pointing devices, such as a mouse, does not penetrate through overlapping elements even if the elements are not visible. This is also true for positioned elements with a negative z-index unless:

• The parent is a scrolling container (that is, its overflow property is set to auto or scroll).
• The parent is positioned (that is, its position property is set to absolute, relative, or fixed).
