title: html5 NAV TAG proper usage
body: <p>I've begun to use html tags on my pages, and I'm trying to determine what is the proper usage of the NAV tag. I've read the documentation, and it seems like I should be okay with what I have, but I noticed that most other developers have their navigation 'blocks' within "ul" "li" tags. I've using divs. </p>
  
  <p>My question is, what are the pros / cons to using "ul" "li" tags rather than divs? </p>
  
  <p>And would the following work with nav? </p>
  
  <pre><code>&lt;nav&gt;
      &lt;div id="navBar"&gt;
          &lt;div id="navItem1"&gt;&lt;a&gt;&lt;/a&gt;&lt;/div&gt;
          &lt;div id="navItem2"&gt;&lt;a&gt;&lt;/a&gt;&lt;/div&gt;
          &lt;div id="navItem3"&gt;&lt;a&gt;&lt;/a&gt;&lt;/div&gt;
          &lt;div id="navItem4"&gt;&lt;a&gt;&lt;/a&gt;&lt;/div&gt;
      &lt;/div&gt;
  &lt;/nav&gt;
  </code></pre>
