The top layer is the layer that appears on top of all other layers. It is the highest layer in the stack, meaning it is visible and covers any other layers beneath it. In most design and editing software, the top layer is the one that was most recently added or moved to the top position.
For example, in a 2D drawing program, you might have several layers with different objects on them. If you want a particular object to be visible on top of all other objects, you need to move its corresponding layer to the top of the layer stack. This allows you to control the visual hierarchy of your design, ensuring that the most important elements are clearly visible.
