PX to REM Conversion Guide

REM (Root EM): Relative to the root (html) font size, typically 16px

EM units: Relative to the parent element's font size for more flexibility

Responsive design: REM units scale consistently across the entire page when root size changes

Default root size: Most browsers default to 16px, but users can change this in settings

Calculation: Formula: px value ÷ root font size = rem value (e.g., 24px ÷ 16px = 1.5rem)

Accessibility: Using REM units respects user font size preferences better than pixels
