A style object represents the formatting and layout of characters or paragraphs within the text of a topic object in the Author-it editing environment. All text within a topic object must be tagged with a style object. This way your content will have a consistent and manageable look and feel.
The style object also contains a link to a style in a Microsoft Word template for the printed documentation, a definition for how the same style will be represented in the Windows Help, and a definition for a cascading style sheet (CSS) style in HTML.
Note: In Author-it, you can update properties on all style objects, however there is a small group of style objects that need to retain their original Style object names on the General tab as they are referenced during the publishing process.
The Style element represents an Author-it Style object, and contains all of its properties.
