A style sheet is a file that contains formatting information that you can assign to the topics in your RoboHelp project. By implementing a style sheet, you provide a uniform appearance throughout your project. In addition, a style sheet reduces the work necessary to format your topics, because you need to establish your formatting decisions only in your style sheet instead of formatting items individually in all your topics, which can be time-consuming and produce inconsistent results.
You should almost never format any text manually. That is, don't select text within a topic and then apply a font, font size, font color, etc. Doing so will put in overrides, preventing the style sheet from working correctly within the manually formatted topic. To get the style sheet to work properly again, you would have to remove all the manual formatting codes, which is tedious. Letting the style sheet control all aspects of your topic presentation eliminates this problem. Then, if you change your mind about any of the formatting, you need only to edit the style within the style sheet to update every topic at once.
Users prefer a consistent appearance across a project, because it helps them to recognize, at all glance, that all the topics relate to each other as part of a whole document. Any formatting inconsistencies can leave users wondering if they've left your document and are viewing something new or if they've made some kind of mistake. Any such distractions from the content can contribute to user frustration.
The Styles dialog appears and is ready for you to begin modifying. Once you save your project, you will find your style sheet in the Project Manager pod, located inside the Project Files folder. You can edit your style sheet at any point by double-clicking it.
If you're working on a RoboHelp project for a class project, you need to set the following styles at minimum: Heading 1, Heading 2, Normal, and Lists, as covered below.
