Footer and Address
The <footer> element represents the footer for its nearest ancestor sectioning element. A page footer typically contains copyright information, related links, legal notices, and contact details. Like <header>, a <footer> can also appear within an <article> to mark author information or article metadata.
The Address Element
The <address> element, when placed inside a <footer>, provides contact information for the page or site owner. When placed inside an <article> it provides contact information for the article's author. Do not use <address> for arbitrary postal addresses unrelated to the document — use a <p> or <div> for those instead.
