What are Headers and Footers?
Headers and footers contain text and/or graphics which appear at the top (header) or bottom (footer) of every page (or designated pages) of your Microsoft Word document. They are used for a variety of purposes, most commonly for page numbering and dates.
To open up the header or footer, click on View from the menu bar and choose Header and Footer (you can also press Alt+Shift+H). Or, if there is an existing header or footer, you can just double-click into it to open up that area.
Your insertion point will move to the header area on the page where your insertion point was. Headers and footers are designated by a dotted border. The header is at the top of the page and the footer is at the bottom. The Header and Footer toolbar will also open up. It may appear in the toolbar area at the top of the document, or may appear "floating" near the header or footer.
The Header and Footer toolbar contains the buttons you'll need to insert page numbers, insert dates, and change the overall formatting of your header or footer. Here is a detailed explanation of the Header and Footer toolbar:
