Frequency Asked Questions

What is a REM unit in CSS?

REM stands for 'Root EM' and is a relative unit based on the root (html) element's font size. If the root font size is 16px, then 1rem = 16px.

Why use REM instead of pixels?

REM units respect user browser settings and make responsive design easier. They scale proportionally when users adjust their default font size, improving accessibility.

How many REM is one inch?

At standard web settings (96 DPI, 16px root font), 1 inch equals 6 rem. This can vary based on your DPI and root font size settings.

How do I change the root font size?

Set the font size on the html element in CSS: `html { font-size: 16px; }`. This becomes your rem baseline.
