How to hide an index section on mobile

Site URL: http://rog.studio

Looking to hide sections of the home page index when it cuts to mobile.
i've found code to hide the image, but not the entire section.

Brine Template, with Parallax.

Which section?

Hi Tuanphan - looking to hide some of the entire child sections (4,5,6,7) in the home index when it cuts to mobile

Can you take a screenshot section 4 & section 7?

Loose screen grabs are attached (viewed in Mobile, in chrome).

Looks like Chrome calls section 4 "new-page-1" and section 7 "new-page-4" if this helps.

Add to Home > Design > Custom CSS

@media screen and (max-width:640px) {
section#new-page-1 {
	display: none;
}
section#new-page-4 {
	display: none;
}
}

Do similar for other sections

You're amazing. Thanks for your help!
