Quick Reference Guide

Why use REM units?

REM (Root EM) units are relative to the root element (usually <html>) font-size. By using REMs, your layout respects the user's browser settings. If a user increases their default font size for accessibility, your entire site scales proportionally.

Tailwind CSS Best Practices

Modern frameworks like Tailwind use REMs by default (e.g., w-4 = 1rem = 16px). Using REMs ensures your custom components align perfectly with the framework's utility classes.

Calculation Formula

REM = Pixel Value / Root Font Size

// Example
1.5rem = 24px / 16px
