The HTML <nav> tag stands for navigation and provides navigation links, either within the current document or to other pages. Typically, the <nav> element includes menus, tables of contents, and indexes. Like the <header>, the <nav> requires both opening and closing tags.[1]
Pro Tip: The <nav> element shouldn't include all links from the web page, only the main navigation. For instance, the <footer> has its own set of links that don't need to be in a <nav> element.
