HTML nav element

The <nav> HTML element represents a section of a page whose purpose is to provide navigation links, either within the current document or to other documents. Common examples of navigation sections are menus, tables of contents, and indexes.

It’s not necessary for all links to be contained in a <nav> element. <nav> is intended only for a major block of navigation links; typically the <footer> element often has a list of links that don’t need to be in a <nav> element. A document may have several <nav> elements, for example, one for site navigation and one for intra-page navigation. aria-labelledby can be used in such case to promote accessibility, see example. User agents, such as screen readers targeting disabled users, can use this element to determine whether to omit the initial rendering of navigation-only content.
