Create or modify a layout
You can modify a layout or create a new customized layout for your book. When you modify a layout, you can apply the changes to existing chapters, sections, or pages that were based on the original layout. For example, if you change the size of an image in a Chapter layout, you can have all pages using the Chapter layout update to the new image size, without having to change each page individually.
If you want to use a modified layout for future chapters or sections but don’t want to change your existing layouts to the modified layout, you can create a new layout. You can also apply a new layout to selected existing pages.
Apply layout modifications to all pages based on the layout
Choose Show Layouts from the View pop-up menu in the toolbar.
In the Layouts pane, select the layout you want to modify.
Modify the layout any way you like by adding or formatting placeholder text, images, and objects.
In the Layouts pane, click Apply Changes.
Create a new layout
Each chapter, section, and page has multiple layouts available (one-column, two-column, and so on). You can create more layouts for any of these elements. The easiest way to create a new layout is to duplicate a layout and then modify it.
Change a page’s layout
You can apply a new layout to a single page for a different look.
In the Book pane, hold your pointer over a page (not the first page of a chapter or section), click the triangle, and choose a page layout from the pop-up menu.
