Pug/ Jade - input is a self closing element: <input/> but contains nested content?
<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>
