Section Breaks, Part 1
Microsoft Word requires a section break when there is a change to page margins, orientation (portrait or landscape) or size, to footer contents or header contents.
How to insert a section break
Go to the Layout tab (formerly called a ‘menu’) on the Ribbon, Page Setup group (the group names are on the bottom of the Ribbon), Breaks option.
The Breaks dialog box pops up, as shown below.
Select the kind of break you need.
