One of the strengths inherent in many of today's documentation tools (including MS Word) is the ability to separate the content from how it will appear to the end user. This separation is possible because of styles.
Styles are typically defined in a separate file from where you are creating your documentation. In the example you will see momentarily, I am using MadCap Flare, which utilizes a separate style sheet with a file extension .css. Every new topic is automatically associated with this file. The definition for each element in my document is stored in the file and then accessible from the topics I create. For example, if I want the title element to be 15pt bold Times New Roman font, I define it in the style sheet file and then apply the Title style to the text I want to change. Here's a demo of this very idea:
The style sheet can be modified for both online and print mediums in Flare. Watch how I modify the paragraph style (p) for print with a serif font here.
Your homework is to modify the default style sheet to your heart's content!
