title: Meta tags explained: http-equiv and charset
body: <p>Which is best? And what is the difference? </p>
  
  <pre><code>&lt;meta http-equiv="content-type" content="text/html;charset=utf-8"/&gt;
  &lt;meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"&gt;
  </code></pre>
  
  <p>or </p>
  
  <pre><code>&lt;meta charset="utf-8"/&gt;
  &lt;meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"&gt;
  </code></pre>
  
  <p>Another thing, I see that Viewport meta tags and meta http-equiv tags do not get the /> closing tags as charset and other meta tags have...why is that?</p>
  
  <p>Thank you</p>
