title: Superscript in CSS only?
body: <p>How can I get superscript done, only in CSS?</p>
  
  <p>I have a stylesheet where I mark the external links with a superscript character, but I'm having a hard time getting the character aligned correctly.</p>
  
  <p>What I have currently, looks like this:</p>
  
  <pre><code>a.external:after {
    font-size: 50%;
    vertical-align: top;
    content: "+";
  }
  </code></pre>
  
  <p>but it doesn't work.</p>
  
  <p>Naturally, I'd use the <code>&lt;sup&gt;</code>-tag, only if <code>content</code> would allow for HTML... </p>
