How FileMaker Pro displays formatting attributes
When you change display attributes for objects, layout parts, or the layout background, FileMaker Pro displays formats according to a defined hierarchy, or precedence. One factor that determines whether format attributes display is whether you save changes at the layout level or the theme level. The following illustration shows the order of precedence in which formatting changes are displayed.
