Css滚动内容阴影效果(Css scroll content shadow effect)

 我正在寻找一个插件（类似于我猜的粘性标题），它可以在可滚动内容上创建盒子阴影效果（当你向下滚动时）。 
 
 我发现了一种使用纯CSS技巧的现有技术 ，它完全符合我的需求（使用background-color属性） 
 
 然而，可滚动的内容会在影子之上 ，我需要它在影子之下。 
 
 有什么插件可以创建相同的效果，但是使用带阴影和动态不透明度的内部div或类似的东西？ 
 

I am looking for a plugin (similar to sticky header i guess) which creates box-shadow effect on scrollable content (while you scroll down).
 
I found an existing technique which is using pure CSS tricks, which does exactly what i need (uses background-color property)
 
However, the scrollable content gets above the shadow, and i need it to be below the shadow.
 
Is there any plugin which creates the same effect but using an inner div with shadow and dynamic opacity or something like this?
