When to Use 128px (8rem)

A value of 128px (8rem) is commonly used for oversized display headings, splash screens, and landing page heroes. In responsive web design, using 8rem instead of 128px ensures your jumbo headings 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 8rem instead of 128px, 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.
