Each object or element is placed on its own layer. Layers are like a stack of see-through sheets, in which each sheet is transparent except for the element. Elements can be see in-front or behind other objects. Layers are accessed from the Layers panel to the right of the window.

Objects at the top of the layers list appear in front of other objects, whereas objects at the bottom appear behind. Each page has its own set of layers, so if the desired layers arent visible, confirm the correct page is selected in the Pages panel.
