title: Vue js app not passing html validation
body: <p>I am running my pages through the w3c validation. Vuejs seems to cause some errors due to the @click directives.</p>
  
  <pre><code>Warning: Attribute @click is not serializable as XML 1.0.
  From line 58, column 1; to line 58, column 24
  &lt;/div&gt;
  &lt;nav @click="toggleNav"&gt;
  </code></pre>
