What is stacking in PowerPoint?

Answer 1

Placing an item over another item. It can be a useful effect. For example, draw two boxes that are exactly the same size, but have different colours or patterns. Then you can animate the second one you drew, like doing the Entrance effect as wipe down or dissolve for example. Then place it exactly over the first box, so that it covers it. When you run the presentation, you will first see the first box. When you start the animation, the new box will appear, giving the effect of the first box changing colour or pattern. You could do several more boxes on top of them, giving different colours or patterns to each one and using different Entrance effects. Items don't have to be the same size or shape to be stacked or completely cover other items. They can overlap. You could do it with circles to create Venn diagrams for example.
