Custom CSS to *not* appear in mobile

Site URL: https://northbarcellars.squarespace.com/

I added padding around some text boxes, but I don't want this custom CSS to appear in the mobile view. How can I make it show for computer browser versions only? 

If your site is SS 7.0

@media screen and (min-width:641px) {
enter CSS here
}

If your site is SS 7.1

/* 992 for desktop or 768 for desktop and tablet */
@media screen and (min-width:992px) {
enter CSS here
}
