Each style has a number of formatting properties. Because styles exist in a hierarchy, each formatting property is combined with the parent style to yield a final result.
For example, if bold = “ON”, then bold formatting is added. If bold = “OFF”, then bold formatted is subtracted from the parent style properties.
Many formatting controls in this dialog box show one of these values:
• On – the property is added to the parent style formatting.
• Off – the property is deleted from the parent style formatting.
• A Number – the value replaces the parent style property.
• = (equal) - the property has no effect, and it inherits the exact same value as in the parent style.
