When you want to add a section break, click Page Layout > Breaks, and then click the sort of section break you want.
What you can do with sections
You can have several different sections on one page, and each one can have its own headers and footers, orientation, formatting, spacing, etc. In other words, a section allows you a lot more control of your document and how you want it to look..
You can use sections to make (or fence in) other formatting changes on the same or different pages in your document, including:
Types of section breaks
A Next Page section break starts the new section on the following page. So from Page Layout > Breaks, you’d click Next Page:
A Continuous section break starts the new section on the same page. One of the most common reasons for using this type of section break is if you’re using columns: By using this sort of section break you can change the number of columns without starting a new page. From Page Layout > Breaks, click Continuous:
From Page Layout > Breaks, click Even Page to start the new section on the next even-numbered page:
Click Page Layout > Breaks, Odd Page to start the new section on the next odd-numbered page.
When you decide to use sections your choices are seemingly endless for how you want your document to look. One of the best and easiest things to do is just experiment and play around with section breaks and see what works for you and the way you want your document to look.
