Your thesis like any other document, book or magazine will contain a number of recurring elements such as headings, footnotes, pagelayouts, the main text, quotations, bibliography, etc. (see illustration 1). All these elements need to be formatted uniformly.
Illustration 1. Page out of a book with examples of recurring elements

You define these various settings once only and they will henceforth apply to the whole document independently of its length.
|Primary paragraph styles||Secondary paragraph styles|
|Text Body||Table of contents of various levels|
|Headings of various levels||Footnotes|
