Swapping sticky text as scrolling element changes

I don’t know how to code, but i am attempting to achieve this effect that i found on on of the forums: Link to sample i found . I would like to do that under the brands section of my page so that while the images scroll the text says something different. I have had trouble aligning the scrolling as well as just getting the text to change. I tried doing a page scrolling animation, but as the sticky element isnt scrolling it didn’t work. I also tried setting my left card background with black to cover the previous text, but it did not synchronize with the picture next to it.
