微妙的背景图像变化 [英] Subtle change of a background-image

问题描述

我一直在尝试通过google找到一个答案，但暂时没有效果。

I have been trying to find an answer via google for a while now but to no avail.

我在网站上遇到了一个有趣的功能： http：// dicksonfong.com/

I've come across an interesting feature on site: http://dicksonfong.com/

此功能涉及背景图片，当片段通过屏幕时，背景图片会从底部显示。我不能描述它更好，这可能是为什么我没有在谷歌上的点击。

The feature involves the background image, which appears to change from the bottom as a section passes up the screen. I can't describe it any better which is probably why I'm geting no hits on Google.

任何人都能识别这个技巧是什么，以及在哪里可以找到源代码来实现类似的东西？

Can anyone identify what this trick is called and where I can find the source code to implement something similar?

提前感谢。
