You can use sections (section: A portion of a document in which you set certain page formatting options. You create a new section when you want to change such properties as line numbering, number of columns, or headers and footers.) to vary the layout of a document within a page or between pages.

Section formatted as a single column
Section formatted as two columns
Just insert section breaks (section break: A mark you insert to show the end of a section. A section break stores the section formatting elements, such as the margins, page orientation, headers and footers, and sequence of page numbers.) to divide the document into sections, and then format each section the way you want. For example, format a section as a single column for the introduction of a report, and then format the following section as two columns for the report’s body text.
Types of section breaks you can insert
The following examples show the types of section breaks you can insert. (In each illustration, the double dotted line represents a section break.)
Next page inserts a section break and starts the new section on the next page.

Continuous inserts a section break and starts the new section on the same page.

Odd page or Even page inserts a section break and starts the new section on the next odd-numbered or even-numbered page.
