A Word document consists of layers:

• The text layer that contains only text.
• A header/footer layer that can contain text.
• Watermarks, and foreground and background layers that contain graphics, text boxes, and shapes.

You can move document objects between these layers using the Drawing toolbar:

• Click the object you want to move and choose Draw | Order | (your choice of Bring to Front, Send to Back, Bring Forward, Send Backward, Bring in Front of Text, and Send Behind Text)..
