How can I acieve the horizontal scroll (on desktop) on Apple's iPad page https://ift.tt/1FyAlB4

please I'm working on a website that will have some pages scroll horizontally on desktop. I love how fluid Apple's iPad page is – the fact that you move your mouse vertically, but the page scrolls horizontally. How can I achieve that, please?

Thanks
