What is the primary purpose of using headers and footers in a document?

Using headers and footers in a document serves the primary purpose of providing a consistent layout for essential information such as page numbers, document titles, or the author's name across multiple pages. This practice enhances readability and helps maintain a professional appearance throughout the document. Headers and footers ensure that important details are easily accessible to the reader, reinforcing the structure of the document without crowding the main content area.

While some options mention organizing content visually or adding decorative elements, these do not capture the fundamental functionality of headers and footers in providing essential information in a uniform manner. Similarly, changing the background color is unrelated to the specific function of headers and footers, which focus on conveying textual information rather than visual aesthetics.
