About PX to REM
REM (root em) is a relative unit based on the root element's font size. By default, browsers use 16px as the root font size.
Why use REM? REM units scale with user preferences. If a user increases their browser's font size, rem-based layouts adapt automatically.
Formula: rem = px ÷ base font size
