title: Superscript inside a p:after content tag
body: <pre><code>.class {
      &amp;:after {
          content: "m3/s";
      }
  }
  </code></pre>
  
  <p>I want to add a unit declaration via :after tag. Is it possible to make the <code>3</code> superscript?</p>
  
  <p>This obviously doesn't work:</p>
  
  <pre><code>.class {
      &amp;:after {
          content: "m&lt;sup&gt;3&lt;/sup&gt;/s";
      }
  }
  </code></pre>
