What is the purpose of using a "footer"?

The purpose of using a footer is primarily to display information such as page numbers or the document title at the bottom of each page. This practice enhances navigation and organization within a document, allowing readers to easily find their place or reference the content. Footers serve as a consistent element that provides important contextual information throughout the document, ensuring that each page is clearly identified, which is particularly useful in longer texts or reports.

In contrast, while citations can be placed in footers, their primary role is more about providing reference rather than general pagination or titles. Increasing the size of the text does not relate to footers, as footers typically use standard text sizes for readability. Adding decorative elements can enhance a document’s visual appeal, but it is not the main function of a footer, which focuses on providing structured, useful information.
