A Style is simply a Condition saved to the database for use in other Bids - sort of Condition Template. There are four built-in Styles: Linear, Area, Count, and Attachment that always show in every Bid, these cannot be changed.
The Condition Style Library contains every saved Style for a database. A Condition Style may be modified at any time - changing a Style does not affect any Conditions created previously. When a Condition is saved as a Style it automatically becomes part of the Style Library.
A Style Set contains multiple Styles organized into logical groups. Style Sets allow a user to quickly add a group of Styles to a Bid.
To learn more about creating Conditions, saving Conditions as a Styles, and setting up Style Sets, refer to Chapter 11 (Conditions and Zones).
Remember, a Style is simply a saved Condition and a Style Set is just a group of Styles (saved Conditions) that can be added to a Bid all at the same time.
