屬性

這個元素只包含全局屬性。

使用說明

  • 并非文件的所有鏈接都必須位于<nav>僅用于主要導航鏈接塊的元素中,通常<footer>元素通常有一個不需要在<nav>元素中的鏈接列表。

  • 一個網(wǎng)頁也可能含有多個<nav>元素,例如一個是網(wǎng)站內(nèi)的導航列表,另一個是本頁面內(nèi)的導航列表.

  • 對于屏幕閱讀障礙的人,可以使用這個元素來確定是否忽略初始內(nèi)容.

例子

在這個例子中,一個<nav>塊被用來包含<ul>鏈接的無序列表()。使用合適的CSS,可以將其顯示為側欄,導航欄或下拉菜單。

<nav class="menu">  
    <ul>    
        <li><a href="#">Home</a></li>    
        <li><a href="#">About</a></li>    
        <li><a href="#">Contact</a></li>  
    </ul>
</nav>
