Understanding REM vs EM Units

REM (Root EM) units are relative to the root font size of the HTML document (typically set to 16px by default). Changing the root font size scales all REM values across the entire page uniformly, making layouts highly accessible and responsive.

EM units are relative to the font size of their direct parent container. If a parent element has a font size of 20px, then 1em within that element equals 20px.
