当用户在父div上滚动时，child应该滚动到结束，然后页面滚动应该继续。
我尝试了这种反向逻辑 Scrolling in child div ( fixed ) should scroll parent div
但是不起作用。请建议如何使其正常工作。
.scrolling-child{ height: 50px; width:400px; border:1px solid green; overflow:scroll; }
.parent { height: 5000px; width:100%; padding: 20px 0; border:1px solid red; overflow:scroll;}<div class="parent">
<div class="scrolling-child">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

如果我正确理解，只需添加位置：固定;滚动子div。见下文。
.scrolling-child{height: 50px; width:400px; border:1px solid green; overflow:scroll; position:fixed;}
.parent {height: 5000px; width:100%; padding: 20px 0; border:1px solid red; } <div class="parent">
<div class="scrolling-child">
