❓ Frequently Asked Questions

Divide the pixel value by the root `<html>` font size (standard browser default is `16px`). For example, `24px / 16 = 1.5rem`, and `14px / 16 = 0.875rem`.
Hardcoded `px` values ignore the user's browser accessibility font-size preference (WCAG 2.1 SC 1.4.4). Relative `rem` units scale proportionally when visually impaired users zoom their default browser text size.
SI decimal storage uses powers of $1000$ ($1\text{ GB} = 1000\text{ MB}$), while binary memory addressing (IEC standard) uses powers of $1024$ ($1\text{ GiB} = 1024\text{ MiB}$).
