Each Theme subsection includes several properties whose values are referenced by one or more Style properties. The property values in Theme subsections are set when you choose a Theme. You may modify the properties if desired.
The Theme.Body Text section includes style properties that affect the text that appears in the site. Most of the text on the site inherits these properties. Many text items are altered by more specific styles found under the Styles section.
See the Styles Section help page for more details.
