title: Adding HTML entities using CSS content
body: <p>How do you use the <strong>CSS</strong> <code>content</code> property to add <strong>HTML</strong> entities?</p>
  <p>Using something like this just prints <code>&amp;nbsp;</code> to the screen instead of the non-breaking space:</p>
  <pre class="lang-css prettyprint-override"><code>.breadcrumbs a:before {
    content: '&amp;nbsp;';
  }
  </code></pre>
