rem() - CSS | MDN

https://developer.mozilla.org/en-US/docs/Web/CSS/rem

“The rem() CSS function returns a remainder left over when the first parameter is divided by the second parameter, similar to the JavaScript remainder operator (%). The remainder is the value left over when one operand, the dividend, is divided by a second operand, the divisor. It always takes the sign of the dividend.” (the page’s own description)
