Why there is a small white space when it scrolling horizontally?

[Xenex122]

So I don't much any problem here..The only problem is why is there like a little space in edges of width of the gallery-container? Is this just a normal case? That's all thank you...the codes is all working but I don't know about the little white space edges.

You have those elements set to display inline (well, grid-inline which is the same in this context) which honors white space. So those gaps are literally the white space from the markup. See this answer:

So just eliminate the space in the markup and you'll be fine. It has nothing to do with GSAP
