Help in creating continous looping animation

Hey guys!
I am trying to figure out how to create a continous looping animation on load. Basically I wanna have a row of product cards that keep scrolling. So more cards appear from the right as the present ones disappear in the left.

It’s similar to what Ran has done here

Would appreciate any immediate help, need to ship this by tomorrow! Thanks.
