Master pages control the general layout of all the different sections in your book. The master page determines the page margins, where the running headers and footers go and what kind of content should appear in them, and how to format that text.
You can configure 5 different master pages: chapters, 2 types of frontmatter, backmatter, and parts. While these master pages are applied to certain types of sections by default, you can change the master page that is used in any section, in the Sections & Text toolset.
Each type of master has 4 pages that can be configured:
The first page of the section: You can change the top and bottom margins for the first page of the section, or change the running header and footer content. For example, you might choose to insert just the page number at the bottom of the first page, and then to include full running headers and footers on your recto and verso pages.
Recto and verso pages: These are the main content pages of your section, and this is also where you set the inside and outside margins that will be applied to all the pages in your section (including first and blank pages).
Blank pages: Sometimes a section will include pages that don’t include any book content—for example, if this section ends on a recto page, but the next section is required to also start on a recto page, then an extra blank verso page will be added to the end of the first section. In these cases, you can choose to suppress the running header and footer content, or have different running headers and footers appear.
Running headers and footers can consist of text content, or use our built-in variables. To add text to your running headers or footers:
Click inside the text box, and type an opening quotation mark (“).
Now type the text that you want to appear, and then type a closing quotation mark (”).
Finally, press the Enter or Return key. Your text will appear as a gray bubble. To remove your typed text, simply press the X immediately to the right of the gray bubble.
Variables let you insert dynamic content that is pulled right from your book text, like the most recent chapter title, the book title, or the author name. You can also insert a variable to dynamically add the up-to-date page number. To include a variable, simply click on it and it will appear in the text box as a green bubble.
You can also combine text and variables, by following the same steps above for each type of content you want to include.
