A stylesheet is a set of graphical and typographical specifications that may be used in a document. The fonts, font sizes, colors, and other layout characteristics specified in the style sheet apply to the entire document, which can be a brochure, a magazine, or a book.

The term, which originated in the printing industry, has been adopted in e-publishing and e- journaling. The description language for stylesheets is Extensible Stylesheet Language(XSL).
