      setTimeout(e, 1e3 / 60)
    }, i(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: fixed;}.heart:after{top: -5px;}.heart:before{left: -5px;}"), n(), r()
  }(window, document);

注：可先新建txt文本，然后将后缀改为.js。

在主页面中插入js文件

打开文件blogs/themes/indigo/layout/layout.ejs，插入以下代码：

1
<script type="text/javascript" src="/js/love.js"></script>

注：src为love.js文件的路径，且将行代码插入到标签里。

另一种方便的方法，就是直接插入在线js

1
2
//引入小心心特效
<script src="https://cdn.jsdelivr.net/gh/Sanarous/[email protected]/js/clicklove.js"></script>

重新生成文件并deploy
