What is the difference between `min-width` and `max-width` in media queries?

beginner

Re-explain

min-width: Styles apply when viewport is equal to or larger than specified width (mobile-first)
max-width: Styles apply when viewport is equal to or smaller than specified width (desktop-first)

/* Mobile first */
@media (min-width: 768px) { /* Tablet and up */ }

/* Desktop first */
@media (max-width: 767px) { /* Mobile only */ }

Mobile-first is generally preferred for performance.
