#71. Changing the Stacking Order
Every object on a page occupies a specific place in the page's stacking order. The first object you create on a page is placed at the bottom of the stack of objects. Each new object is placed successively higher in the stack.
If objects don't overlap, their stacking order is not important; however, if objects overlap, the stacking order determines which object is visible in the overlapping areas. You may find that you need to move objects forward or backward in the stacking order to create the desired result (Figure 71).
Figure 71. Four objects are stacked upon each other (left). The text frame is at the top of the stack; the empty circular frame is at the bottom. Selecting the circular frame and choosing Object > Arrange > Bring to Front produced the result on the right.
The Arrange command (Object menu) displays four options for changing the position of the selected object in the stacking order:
Layers have their own stacking order the same as objects. (For more about layers, see #82.) When you choose any of the four Arrange commands (Bring to Front, Bring Forward, Send to Back, and Send Backward), the selected object moves forward or backward only within its own layer. This means, for example, that if you choose Object > Arrange > Bring to Front, the selected object may not be the frontmost object if it's on a layer that's below another layer. To place an object in front of all other objects, move it to the front of the frontmost layer.
If you place objects on a master page, they're placed at the bottom of the stacking order behind objects that you place on the same layer on a document page. If you want to place master objects in front of objects on document pages, create a layer for the master objects and place that layer on top of the layer you use for objects on document pages.
