Thank you for your reply.
When I searched before, I also saw that a wrapper should be added outside the element, so I .Banner has been added .pin-container.I didn't expect to add the first element in the template. Thank you very much for your correction.
However, there is still a problem that existed before. When switching to the about page and then switching back to the home page, page scrolling will cause page exceptions.
I added
ScrollTrigger.refresh()
in the activated of each page.
It's solved, but I don't know if it's a good way
