Understanding the impact of using relative units like REM over fixed units like pixels (PX) is crucial for designing with accessibility in mind. Here’s why REM should be your go-to unit for font sizing:
Using REM units ensures fonts are more accessible, providing a scalable unit that adapts to users' preferred text sizes.
PX: No matter the user’s preference, a 16px font size remains 16px
REM: The font size scales according to the user’s preference, and a 1 rem (equivalent to 16px) font size will be scaled as the user changes their settings.
