Inherit inherits the visibility property of the layer's parent. Visible displays the layer contents, regardless of the parent's value. Hidden hides the layer contents, regardless of the parent's value. Z-Index Determines the stacking order of the layer. Higher numbered layers appear above lower-numbered layers.
Values can be positive or negative.
It's easier to change the stacking order of layers using the Layer palette. See Changing the stacking order of layers . Visible increases the layer's size so that all of its contents are visible. The layer expands down and to the right. Hidden maintains the layer's size and clips any content that doesn't fit.
