Layui 解决动态图标不动的问题

　　　　　　<i class="layui-icon layui-icon-face-smile" style="color: red; font-size: 100px;"></i>
          <i class="layui-icon layui-icon-rate-half" style="font-size: 30px; color: #1E9FFF;"></i>
          <i class="layui-icon layui-icon-login-weibo" style="font-size: 30px; color: #1E9FFF;"></i>
          <i class="layui-icon layui-icon-loading-1 layui-anim layui-anim-rotate layui-anim-loop" style="font-size: 30px; color: #1E9FFF;"></i>
          <i class="layui-icon layui-anim layui-anim-rotate layui-anim-loop" style="font-size: 120px; display:inline-block;">&#xe63d;</i>   

动态图标必须写layui封装的样式  ‘layui-anim layui-anim-rotate layui-anim-loop’
