In graphic design and digital art, stacking refers to the order in which objects or layers appear on the Z-axis, that is, from front to back. This concept is also known as "Z-order," "stacking order," or "layer order."
Objects created later typically appear in front of those created earlier, and objects can be moved forward or backward in the stack to control which ones appear in front of others.
Changing the stacking order of objects can help create the illusion of depth, overlap elements in interesting ways, or simply ensure that the right objects are visible in a complex design. As always, the best practices for stacking and reordering depend on the specific needs and goals of your design. All objects are stacked vertically as they are created.
In DEX you can change the stacking order.
