    <li data-row="1" data-col="1" data-sizex="2" data-sizey="1" onclick="location.href='https://registry.hub.docker.com/repos/emccode/';">
      <div data-id="docker_hub_stars" data-view="List" data-unordered="true" data-title="Docker stars" style="background-color: #9b59b6"></div>
      <i class="icon-star icon-background"></i>
    </li>
    <li data-row="1" data-col="1" data-sizex="2" data-sizey="1" onclick="location.href='https://registry.hub.docker.com/repos/emccode/';">
      <div data-id="docker_hub_pulls" data-view="List" data-unordered="true" data-title="Docker pulls" style="background-color: #9b59b6"></div>
