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>
