Trackpad Macbook

Hi,

I have got a problem with one of my websites. The horizontal scrolling works perfectly with my mouse, but when I use the Macbook trackpad, it goes way quicker and it feels laggy. There is also no way of scrolling horizontally with the trackpad, it only works when scrolling vertically.

Do you have a fix for this problem ?

Thank you,
Diogo
