Horizontal Scroll Transition (Background change)

Hello evereyone,

i hope someone can help me with my issue.

I have created a cms based horizontal scroll on the following site:

https://preview.webflow.com/preview/horizontal-scroll-95dfed?utm_medium=preview_link&utm_source=dashboard&utm_content=horizontal-scroll-95dfed&preview=4755207669875383468035cbecd4fd6f&workflow=preview

Because i want to put in different images and videos as a background i need a “smooth transition”.

In vertical scrolling i have something like this backgorund color change:

Is there any way to do such a transition as well on horizontal scrolling? It should only show one “item”, then the next one appears when scrolling on.

Thanks a lot! I really don’t get any further at this pointl
