Usage notes
- It's not necessary for all links to be contained in a <nav>element.<nav>is intended only for 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-labelledbycan 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.
Examples
In this example, a <nav> block is used to contain an unordered list (<ul>) of links. With appropriate CSS, this can be presented as a sidebar, navigation bar, or drop-down menu.
<nav class="menu">
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Contact</a></li>
  </ul>
</nav>
The semantics of the nav element is that of providing links. However a nav element doesn’t have to contain a list, it can contain other kinds of content as well. In this navigation block, links are provided in prose:
<nav>
  <h2>Navigation</h2>
  <p>You are on my home page. To the north lies <a href="/blog">my
  blog</a>, from whence the sounds of battle can be heard. To the east
  you can see a large mountain, upon which many <a
  href="/school">school papers</a> are littered. Far up thus mountain
  you can spy a little figure who appears to be me, desperately
  scribbling a <a href="/school/thesis">thesis</a>.</p>
  <p>To the west are several exits. One fun-looking exit is labeled <a
  href="https://games.example.com/">"games"</a>. Another more
  boring-looking exit is labeled <a
  href="https://isp.example.net/">ISP™</a>.</p>
  <p>To the south lies a dark and dank <a href="/about">contacts
  page</a>. Cobwebs cover its disused entrance, and at one point you
  see a rat run quickly out of the page.</p>
