title: Should I use an anchor or input tag in a navigation bar?
body: <p>I don't know what I should use in my nav bar:</p>
  
  <pre><code>&lt;li&gt;&lt;a&gt;&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;li&gt;&lt;input&gt;&lt;/li&gt;
  </code></pre>
  
  <p>In all tutorials it is <code>&lt;a&gt;</code> but why? In the nav bar I have a link to the next page and this solution is correct? But what if a button in the nav-bar opens a popup window? In this situation should I use <code>&lt;input&gt;</code> or <code>&lt;a&gt;</code>?</p>
