In web design, a footer is a section at the bottom of a webpage and typically contains information such as copyright notices, legal disclaimers, contact details and links to other pages or resources on the website. The footer can also include navigational elements such as a sitemap or social media links. Website footers are an important component of the user experience as it provides essential information and can improve the accessibility and usability of the site. Additionally, search engines may use the information in the footer, such as contact information and links to other pages, to better understand and index the content of the website.
