You use the pages in the Content Defaults category to set the font and color defaults for the following components:
Introduction/End Frame: These frames appear at the beginning and end of each topic, displaying introductory and concluding text that the content author enters in the Topic Editor. In addition, the Introduction text for each topic displays in the Introduction pane in the Outline Editor and Player windows. By default, Introduction and End frame text uses the 10 point Arial font and a pale yellow background color. Changing these options affects the appearance of the Introduction pane, as well as the Introduction and End frames in all play modes.
String Input: String inputs are events that occur while recording a topic when you are typing, such as entering information into a field. When a user plays the topic in Try It! mode, the user must enter the specified text to move to the next step. The action area (the area in which the user must type the text) uses an 8 point font size in the default MS Sans Serif font, and white background color shown in the sample box in the String Input page You can change these options to better simulate the application in which you are recording.
Web Page: Web pages contain extra information that can be attached to the content. Web pages can display a simple note or definition of terms, or display a more complex arrangement of text, graphics and hyperlinks. The default setting is a 10 point Arial font and a white background color.
