MasterBorders on Imported Pages
When you import a template, or create a new site based on a template, the new pages have the same MasterBorders as they did in the site from which they were exported (the source site). When you import, all MasterBorder styles that were present in the source site will appear in the destination site. So, for example, unless you changed the name of the Default MasterBorder style in either the source or the destination site, you will see Default listed twice in the list of MasterBorder styles available on the Layout tab of the Properties palette. In this case, it's easy to determine which one is the site's default: the site's default is always the first one on the list, even if you edit its name.

When you create a new site based on imported pages, NetObjects Fusion gives the site's Default MasterBorders the following widths in pixels: Top, 10; Left, 10; Right, 10; Bottom, 40. This means any new pages you create in the site will also initially have these margin widths, unless you edit the Default MasterBorder.

In Site view, when you import HTML pages from a local or remote site, NetObjects Fusion gives each imported page the site's Default MasterBorders. This means when you first view an imported page in Page view, its size will be equal to the site's Default MasterBorders plus the size of the imported page.

NetObjects Fusion's Page view supports two methods for adding HTML pages created in other applications: Import Page and External HTML. When you import a single HTML page using the Import Page command, NetObjects Fusion expands the Layout if needed to accommodate the imported page, but makes no adjustment to the page's MasterBorders. When you specify that a NetObjects Fusion page should be replaced by an External HTML page by using the External HTML option on the Layout tab, NetObjects Fusion makes no adjustment to its own page size; it simply makes sure your site visitor will see that External HTML page in the browser.
