The jQuery plug-in windowScroll implements single-screen scrolling effects_jquery

Looking back, I can’t bear to look at the code that I was once proud of. It once seemed that the effect of the bunker can now be slightly achieved. Society is moving forward, and people have to move forward too.
Refer to the up and down scrolling effect of Sogou browser version 4.2 homepage. It mainly implements the up and down and left and right scrolling logic of the entire window, and there is still a lot of room for expansion. I hope you can provide more comments and suggestions.
The code is as follows:
