如本站右下角的演示，是从jq22拿过用来的，但是源码不完整，而且有很多缺陷，现在完善修复一下，放出来给大家

html代码，请自行修改头像链接：

<div class="livechat-girl animated"> <img class="girl" src="头像的链接">
  <div class="livechat-hint rd-notice-tooltip rd-notice-type-success rd-notice-position-left single-line show_hint">
    <div class="rd-notice-content">嘿，我来帮您！</div>
  </div>
  <div class="animated-circles">
    <div class="circle c-1"></div>
    <div class="circle c-2"></div>
    <div class="circle c-3"></div>
  </div>
</div>

附上js代码

上面部分是判断是否手机移动端，下面是判断后，针对移动设备点击后跳转到相对应的客服链接

把上面的代码放到相对应的位置就可以了，如果是使用自媒体博客Spimes主题的话

分别丢到代码框里面即可
