Why use REM over PX?
01
Accessibility
When users change their browser font settings, REM units scale proportionally, while PX values remain fixed, potentially breaking your design for users with visual impairments.
02
Responsive Design
You can scale your entire UI by changing just the root font size in a media query. This makes mobile optimization significantly easier to manage.
