+
+Z-index is a CSS property that controls how elements stack on top of each other. The stack order is defined by an element with a higher z-index appearing on top of an element with a lower z-index.
+
+Z-index and shadow are used together to help distinguish each layer in the stack. Shadow provides the visual element and z-index provides the structural element. Please refer to the [shadow](/salt/foundations/shadow) foundation page if you're using z-index.
+
+## Z-Index ramp
+
+Salt provides z-index tokens that determine an item’s position in the layering order. By providing consistent z-indexes, the design system ensures a predictable hierarchy of visual elements when stacked on top of one another.
