title: HTML5 <input> required attribute but not inside <form>
body: <p>The Required attribute works great inside the form Tags:</p>
  
  <pre><code>&lt;form&gt;
  &lt;input type="text" name="user" required&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>But can I use the required attribute if I cannot wrap it as a form?  Outside of the form this input required does not work for me:</p>
  
  <pre><code>&lt;input type="text" name="user" required&gt;
  </code></pre>
  
  <p>I can replicate it with JavaScript but Id like to know if outside form is possible</p>
