一、子比后台—自定义代码—自定义底部代码。

二、WP后台— 外观 —自定义—额外CSS。

默认是灯笼都在右上角位置，比照原文主要是调整了位置，避免遮挡顶部导航菜单。

如果是一边一个，上面代码开头的.deng-box和.deng-box1修改为下面代码即可。

.deng-box {
  position: fixed;
  top: 40px;
  right: -20px;
  z-index: 999;
}
 
.deng-box1 {
  position: fixed;
  top: 40px;
  z-index: 999;
}@media screen and (max-width: 768px){.deng-box{position: fixed; top: 23px; right: 0; z-index: 999;}.deng-box1 { position: fixed; top: 23px; z-index: 999; right: auto; }}<br>
