A more extreme example of this is http://www.basscss.com/ where CSS classes are reusable and composable. E.g. a list could be:

    <ul class="list-reset">
      <li class="inline-block mr1 h4 border border-red">Half-Smoke</li>
      <li class="inline-block mr1 h4 border border-green">Kielbasa</li>
      <li class="inline-block mr1 h4 border border-blue">Bologna</li>
      <li class="inline-block mr1 h4 border border-yellow">Prosciutto</li>
   </ul>
