Styles contain formatting instructions that can be combined with other styles. When a style is applied to text, it combines with the underlying text properties. The basic text properties are set in each file type's font settings. You can control this with the Options > File Type Options command. Style properties are combined with the basic text properties. Styles also can inherit properties from other "parent" styles. See: Parent Styles.
The formatting properties of all the applicable styles are combined with the font selected in a given file's type.
Figure 3.6 Style properties combine with each other, and with the default font set in the File Types dialog box.
