I’ve realised that there’s a large blank space to the right hand side of my page, meaning that on all devices you can scroll horizontally (not wanted!). I don’t have any interactions that mean elements are hanging off the page, and can’t work out what is causing it. Help!
You have removed the overflow:hidden on the mASK element of the slider, which prevents bleeding.
Reapply overflow-hidden to the section .testimonials-section.
