Frequently Asked Questions
What is REM?
REM (Root EM) is a CSS unit relative to the root font size. 1rem equals the font-size of the HTML element (typically 16px).
What is the default base size?
The default browser base font size is 16px, so 1rem = 16px by default.
Why use REM instead of PX?
REM units scale proportionally, making designs more responsive and accessible. Users can change their browser's base font size without breaking layouts.
