What is the purpose of the <footer> tag in an HTML document?

The purpose of the

tag in an HTML document is to define the footer for a document or section. This tag serves as a container for information that is typically found at the bottom of a webpage or a specific section of content, such as copyright statements, links to privacy policies, contact information, or other supplementary information pertinent to the overall content.

Using the

tag helps to semantically organize the structure of the document, enhancing accessibility and improving search engine optimization. By clearly marking the footer section, it allows browsers and assistive technologies to understand the layout better, making it easier for users to navigate the page.

The

tag is designed specifically for this type of content, providing clarity on its role within the document, which sets it apart from other elements that focus on main content, metadata, or interactivity.
