A footer is usually found at the bottom of a webpage, and can contain information such as website contact information, privacy policies, copyright information, and disclaimers. The footer often also contains links to other pages within a site, like the home page or other sections of the site. Footers are commonly used to provide quick access to some of the most important information on a website. By providing this information in a clearly-marked section, users can easily reference it when needed.
A well-designed footer can also improve the usability of a site, as it organizes the relevant information in a clear, concise manner.
