web前端分享HTML5中的nav标签 _HTML5

好程序员web前端分享html5中的nav标签， nav标签全称navigation ，顾名思义，是导航的意思。根据HTML5的相关标准定义如下： "A section of a page that links to other pages or to parts within the page:

a section with navigation links." 中文翻译大概意思是”页面中的一个用来链接到其它页面或者当前页面的区域：一个含有导航链接的区域” 。这里非常清楚的定义了nav标签的功能，这里和header类似并没有指定必须是主导航，也可以是页面其它部分的子导航。如下：
1.<h3>gbin1.com文章列表</h3>
2.<nav>
3. <ul>
4. <li><a href=https://www.isolves.com/it/cxkf/yy/html5/2019-08-16/"#html5">HTML5文章介绍
5. <li><a href=https://www.isolves.com/it/cxkf/yy/html5/2019-08-16/"#css3">CSS3文章介绍
6. <li><a href=https://www.isolves.com/it/cxkf/yy/html5/2019-08-16/"#jquery">jQuery文章介绍
7. <ul>
8.</nav>
在上面这个例子中，我们看到这里只是一个区域的文章导航，同样也可以使用nav定义一个小型的页面内导航。但并不是页面上的所有链接团体都需要放在nav标签内，它主要是由页面的主要导航块组成。例如，我们通常在网站的页脚里放一组链接，包括服务条款、网站介绍、版权声明等，这时，我们通常使用footer ，而不是nav 。
一个页面可可以包含多个nav标签，作为页面整体或者不同部分的导航。在下面的例子中，有两个nav标签，一个是网站的主体导航，另外一个是当前页面本身的辅助链接导航。

nav标签本身并不要求包含一个列表，它还可以包含其它内容形式。
