title: How to add text to label in CSS
body: <p>I need a smart way to add red asterisk to text placed between label tags.
  Is there any way to intercept the content and add some extra text? I can add a class to this labels if necessary.
  I must do it in CSS.</p>
  
  <p>For ex:</p>
  
  <pre><code>&lt;label&gt; Name and surname &lt;/label&gt;
  &lt;input type="text" required name="NameSurname"&gt;
  </code></pre>
  
  <p>shoud be:
  Name and surname*****</p>
