为什么不先移动鼠标就不能滚动视差？

所以我试图制作一个带有视差登陆图片的网页。为了使视差效果发挥作用，它具有更高的高度，因此用户必须向下滚动。这将在侧面仅为此视差创建第二个滚动条。到目前为止，一切都很好。问题是当我向下滚动到视差末尾时，第二个滚动条没有自动激活，我必须稍微移动一下鼠标才能继续滚动网页的正常内容。这是我的问题的有效示例：

到达视差结束后是否有任何方法可以使它继续滚动而无需先移动鼠标？

感谢您的任何帮助！

[首先，我建议在position: relative;中添加.parallax以便添加到remove the double scroll。

您遇到的问题是与浏览器相关的滚动问题，而不是代码问题（例如，它确实适用于Firefox，但不适用于Chrome）。因此没有“修复”。

但是显然还有其他方法可以使用视差来防止问题发生，例如不依靠浏览器的滚动而手动滚动每个视差。
