How to correctly scroll a website horizontally on a Mac?

Question

JavaScript

Hey! Help with safari please. The problem is this. Theme for wordpress, horizontal. The theme itself is portrait, and in it the scroll did not work at all. I found a solution on js: mouse wheel, set it up, everything is super on computers. But then a poppy appeared and a safari in which miracles happen. Ah, yes. They also drive around the site. In general, the problem is this: if you scroll vertically. That's all OK, if horizontally, then unknown crap happens.

if you flip, throwing, sideways, it gets stuck a little. If you flip sideways, without taking your hands off, it goes in the opposite direction very slowly.

With all this, on the wheelbarrow, everything is ok on my PC. What's wrong with poppies?? (

Actually, the site itself is here
