title: Pug/ Jade - input is a self closing element: <input/> but contains nested content?
body: <p>I want to create the html like this:</p>
  
  <pre><code>&lt;label class="radio-inline"&gt;
      &lt;input type="radio" name="hidden" checked="" value="Visible"&gt; Visible
  &lt;/label&gt;
  </code></pre>
  
  <p>Pug/ Jade:</p>
  
  <pre><code>label.radio-inline
      input(type="radio", name="hidden", value="0", checked="") Visible
  </code></pre>
  
  <p>But I get an error:</p>
  
  <blockquote>
    <p>input is a self closing element:  but contains nested content.</p>
  </blockquote>
  
  <p>What does it mean? How I can fix this?</p>
