Summary
In Macromedia Flash Basic 8 and Macromedia Flash Professional 8, layers are analogous to transparent sheets of acetate stacked on top of each other. In the areas of a layer that don't contain content, you can see through to content in the layers below. Layers assist you in organizing content in your document. For example, you can keep background art on one layer and navigational buttons on another. Additionally, you can create and edit objects on one layer without affecting objects on another layer.
