title: Add class to body depending on the content of meta tag
body: <p>Sorry for my English but I think its pretty easy to understand.</p>
  
  <p>I use different languages on a website. I want to add a class to the body when the German language is selected. </p>
  
  <pre><code>&lt;meta http-equiv="language" content="DE"&gt;
  </code></pre>
  
  <p>Tried this, but seems like its making no effect:  </p>
  
  <pre><code>   $(function() {
              if  ($("meta[http-equiv='language']").attr("content") === "DE")) {
                  $("body").addClass("german");
              }
      });
  </code></pre>
