When to Use 50px (3.125rem)

A value of 50px (3.125rem) is commonly used for hero headings, display titles, and large promotional text. In responsive web design, using 3.125rem instead of 50px ensures your hero and display text scale proportionally when users change their browser font size settings.

Why Use REM?

REM units are relative to the root element's font-size, making them ideal for accessible, responsive designs. When you write 3.125rem instead of 50px, your layout respects user preferences — if someone sets their browser to a larger font size for readability, all your rem-based values scale up proportionally.
