THE NAV ELEMENT<br />
The nav element defines a block of navigation links. The nav element is useful for creating<br />
a set of navigation links as your document’s primary navigation, a table of contents, breadcrumbs<br />
in a footer, or Previous-Home-Next links.<br />
The W3C mentions that you don’t have to use tags for all navigation links, just major<br />
blocks of links. Because tags are interpreted <strong>by</strong> screen reader software for <strong>the</strong> visually<br />
challenged, <strong>the</strong> software can determine if it should make <strong>the</strong> navigation links available to <strong>the</strong><br />
user immediately or not, depending on <strong>the</strong>ir importance.<br />
The following example shows <strong>the</strong> tag in use:<br />
<br />
Hip-Hop<br />
Modern<br />
Swing<br />
Tap<br />
<br />
The links would display in a Web page as shown in Figure 3-5.
