Custom scrolling elements on JS. Help

Hello!

I am asking for help.
You need to make custom scrolling elements for the blocks, like here news.sky.com/skynews
Search on Habra does not give anything sensible, Google also does not give the necessary options.
There are solutions for a fixed width, and you need to make sure that the scroll is applied to any number of elements, that is, it is rubber.

If someone has options for solving this problem, I will be very grateful!
