关于 rem (rem)
The root em (rem) is a CSS unit relative to the root element's font size, typically 16px in browsers. Unlike em, which compounds when nested, rem always references the same base, making it the preferred unit for consistent, accessible web typography and spacing in modern CSS frameworks.
关于 em (em)
The em is a relative typographic unit equal to the current font size -- in 16px text, 1 em equals 16 pixels. CSS developers use ems for responsive font sizing, padding, and margins that scale proportionally with text size. The em dash character is so named because it was traditionally the width of one em.
