You can arrange text boxes, pictures, AutoShapes, and drawing objects so that they line up with a grid line or a ruler mark. Or you can line up objects relative to each other so that the placement of the objects is based on the placement of another object, group of objects, or the margins.
Align objects in a row
Tip
To align objects down the center of a page, click the Relative to Margin Guides and then click Align Center.
Align an object to another object, a grid line, or ruler mark
The Snap To command sets objects to exert a magnet-like pull on nearby objects.
Selection handles will appear around the object.
Notes
If the guides are hidden, objects will still snap to the guides.
If you have turned on all of the Snap options, Microsoft Publisher tries to snap objects first to a nearby guide. If there's no guide nearby, Publisher snaps to the nearest object. If there are no objects nearby, Publisher snaps to the closest rules mark.
Align objects relative to the margin
Tip
To align objects down the center of a page, select both Relative to Margin Guides and Align Center.
