When to Use 672px (42rem)

A value of 672px (42rem) is commonly used for tablet breakpoints, medium container widths, and content area widths. In responsive web design, using 42rem instead of 672px ensures your tablet containers 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 42rem instead of 672px, 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.
