首先感谢大佬的开源项目

还有店长的教程糖果屋微调合集 | Akilarの糖果屋 Custom Beautify | Akilarの糖果屋

未实现：冰球跟随音乐振动

希望有大佬来解决这个问题，我这个小菜鸡实在搞不定。

有建议请评论区留言，欢迎！！

7.27更新：关闭移动端并根据屏幕大小判断是否引入并开启

最终效果

动画2142

引入js

只针对butterfly主题，其他主题请自己根据情况调整

icebg.js代码在最下面

在_config.butterfly.yml中inject的bottom:插入代码

1
- <script data-pjax src="你自己icebg.js的地址"></script>

建议修改合适后再通过jsd加速插入，因为每个人需求不一样，如果你想要本站一样的效果就改成这样,如果需要自定义请接着看。

当然，建议读者把代码存到自己仓库

如果只需要当背景，而不是头图，到这里就够了，如果想要跟本站一样，参考店长头图透明教程在costom.css文件中加入

1
2
3
4
/* 头图透明 */
#page-header{
  background: transparent!important;
}

注意：因为butterfly版本迭代，店长教程中的配置手机 PC 页面白天黑夜共四个背景图的第一步请按diff代码块配置。因为我就掉坑了

店长教程点这里Custom Beautify | Akilarの糖果屋,建议配合糖果屋微调合集 | Akilarの糖果屋配置手机 PC 页面白天黑夜共四个背景图食用，效果更佳。

然后

然后就没了，就这，对，就这。

自定义

建议有一定基础的朋友进行自定义修改，比如把球改到侧边栏

icebg.js我放在了source博客根目录，方便调试，读者可以根据情况修改。

1
- <script data-pjax src="/icebg.js"></script>

自定义只需要修改icebg.js内的代码就可以了，代码还是挺长的，其他的我也不会了，大家看着办吧，有大佬改记得评论区告诉我一下。
