- Rem is relative to the <html> font size
- All sizes applied in Client-first are in rem.
- The decision to work in rems is directly related to accessibility benefit.
- Every 16px is 1rem when the browser's font size is set to the default in browser settings.
- Every rem measurement conversion in the project is a multiple of 16, e.g. 1024px / 16 = 64rem.
