Horizontal Scrolling CMS by Timothy Ricks is not working


I went through this tutorial: Perfect Horizontal Scrolling CMS in Webflow - YouTube of Timothy Ricks. All looks pretty clear. Unfortunately, this animation is not working on my site. I have compared my site to Rick’s website. No difference for me at all.

Any idea where is the problem?
