In Word headers and footers can keep pages organized and can give Word documents a more professional look.
By default, some of the built-in headers and footers have snippets of text that are called content controls. Content controls can contain information such as the document title or company name, and they allow you to enter this information into a form field.
However, you'll often just want to type a normal header without any content controls. To do this, you'll need to remove any content control fields from the header or footer.
There are many other header and footer options you can use to design these sections of your document. You can review the Header & Footer Tools Design tab to view and explore these options.
