如何将侧导航栏上的用户图标转到中心？以及如何为侧导航栏创建边框？

Question

我正在尝试将用户个人资料图标置于中心位置，以便我最难做到这一点。我也尝试在导航栏周围添加边框，以便它不会显示在我的页面上，我无法弄明白。我正在尝试重新创造优步的所有内容 - 请参阅附图。有人请指出我正确的方向吗？谢谢！

          <div class="col-sm-2 text-center">
[![enter image description here][1]][1]
            <!-- side bar -->
              <div class="row">
                <div class="profile-sidenav-cell">
                    <span class="glyphicon glyphicon-user custom-icon"></span>   
                </div>
              </div>

              <div class="row">
                <div class="profile-sidenav-cell">
                <ul class="side-menu-tabs">
                  <li><a href="/profile">Profile</a></li>
