Why Use Relative Units (EM/REM)?

Relative units allow your design to adapt to the user's browser settings. If a user increases their default font size for better readability, a site using REM units will scale beautifully, maintaining the intended hierarchy and balance.

  • Improved Accessibility for visually impaired users.
  • Consistent spacing and sizing across different devices.
  • Easier maintenance of large-scale CSS projects.
