title: selecting <label> but excluding <label> that contain <input>
body: <p>I have 2 types of labels, normal labels like the first line, and labels that contain a input field within them. What CSS rule can let me select all <code>&lt;label&gt;</code> but exclude all labels that happen to contain <code>&lt;input&gt;</code> within?</p>
  
  <pre><code>&lt;label for="type"&gt;Some Label&lt;/label&gt;
  
  &lt;label for="type"&gt;
     &lt;input type="checkbox" value="1" id="type"&gt;Some Label
  &lt;/label&gt;
  </code></pre>
