In NetObjects Fusion, a page consists of a Layout area and a MasterBorder area. The Layout area is the body of the page. It contains objects that are unique to that page. The MasterBorder is the page margins. MasterBorders contain objects, such as navigation bars, that appear on multiple pages.
You can define multiple Layouts and MasterBorders, then assign one of each to a page. See Working with MasterBorders and Working with Layouts.
