title: Want to use use class name into a before element
body: <p>I don't know if the name of a CSS class can be placed using the "content" of a :: before element in every p tag like so:</p>
  
  <pre><code> &lt;p class="roboto"&gt;Lorem ipsum dolor sit amet, consectetur adipisicing elit.&lt;/p&gt;
  
  .roboto::before {
           content: "p[class] ";
           font-weight: bold;
  }
  </code></pre>
  
  <p>The result should be something like this:</p>
  
  <blockquote>
    <p><strong>roboto</strong> Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
  </blockquote>
