Description

A sidebar is a short piece of text, rarely longer than a single column or page, that is presented outside the narrative flow of the main text.

Sidebars are often used for digressions or interesting observations that are related, but not directly relevant, to the main text.

Processing expectations

Formatted as a displayed block. Sometimes sidebars are boxed or shaded.

DocBook does not specify the location of the sidebar within the final displayed flow of text. The wrapper may float or remain where it is located.
