如果可以加入的话：
- 移动端不能很好地展示，所以请在移动端隐藏此特效；
- IE8及以下无法展示；
- “葬歌”二字暂时用了base64，可以上传为图片缩短代码。

- 代码是可以实现的，建议放在封面栏。具体插入js代码需要联系相关权限人员。--商火（讨论） 2018年6月9日 (六) 15:58 (CST)
- 放在封面栏的话需要调整尺寸，顺便哪些是可以联系的相关权限人员呢？
--丩卩夂忄（讨论） 2018年6月9日 (六) 16:03 (CST)- 先讨论好具体细节吧。刚刚想了想，放封面栏可能有点局促，那就全屏宽放置于“PPTV”一栏如何？然后在移动端隐藏。若没有异议就这样吧。
- 抄送@Imbushuo：您好，我们希望做如上的页面特效来模仿本词条作品的MV风格，希望您同意后将js代码打包为Wight。--商火（讨论） 2018年6月9日 (六) 16:34 (CST)
- 没有异议，那么宽度也不需要修改了，就1280*720。
- 顺便调整了一下代码，可见 User:丩卩夂忄/ZangGe.js
