Frequently Asked Questions
By default, 1 REM = 16px (the browser default root font size). If you change the base font size, 1 REM equals that new value.
REM units scale with the user's browser font settings, making your design more accessible. If a user increases their browser font size, REM-based layouts adjust automatically.
EM is relative to the parent element's font size (can compound). REM is always relative to the root (html) element — more predictable and easier to manage.
