style sheets

a.k.a. template

A file or form that defines the typography and layout of a document in some word processing and desktop publishing programs. When you fill in a style sheet, you specify such parameters as the page size, margins, and fonts. Style sheets are useful because you can use the same style sheet for many documents. For example, you can define one style sheet for personal letters, another for official letters, and a third for reports.
