Style Sheets are NaviSoft's way of getting around some of the limitations of HTML. A style mapping allows you to specify what formatting effect each HTML element should have, so you could have a style mapping where Strong characters are displayed in cyan and italic, while the level 1 headings (Hdg 1) are right justified 36 point text.
The Format->Style Sheet dialogue provides a list of style maps and allows you to attach one to the current page. You can also create new ones (by selecting a base style and pressing the New button), or browse around the net to find existing maps.
If you attempt to attach a local map to a remote page, the map is only used to display the page in the current session and is not saved with the page. If you attach the Normal style, it will remove any map from the page.

HTML allows both logical and physical styles. In GNNpress these styles are listed in the Format->Type Style menu.
The physical styles (Plain, Bold, Italic, Underlined, Fixed Pitch, Superscript, Subscript) describe how the text looks on the page.
The logical styles (Citation, Code, Definition, Emphasis, Keyboard, Sample, Strong, and Variable) describe the content of the tagged text and allow the reader (browser) to determine how it looks on the page. Content can be divorced from presentation.
Logical tags allow the author to specify that a particular line is a level-one heading but does not specify that a level one heading should be, for instance, 24-point Times Roman and centered.
This also allows the user to change the presentation of every occurrence of a particular style type by simply changing its definition within a style sheet.
Within the Style Sheet dialogue the user can decide how the different Paragraph and Heading formats, Type Styles, Lists, and the Horizontal Rule appears on the screen.
