section

Sections provide a way to divide word-processing documents into different parts, such as book chapters or report segments, so that different portions of content can use different formatting. Each section can have different page numbering, headers, footers, and backgrounds.

By default, all the pages in a new blank word-processing document are part of the same section until you specifically add more sections to your document.

You can tell which pages are in the same section in Page Thumbnails view. Touch and hold a page, and a background color appears behind all the pages in the same section.
