    <div class="tree">
      <div class="tree-inner">
        <div class="tree-top"></div>
        <div class="tree-bottom"></div>
      </div>

    <div class="tree small">
      <div class="tree-inner">
        <div class="tree-top"></div>
        <div class="tree-bottom"></div>
      </div>
    </div>
