The element's height is set to the value of min-height whenever min-height is larger than max-height or height.

Syntax

/* <length> value */
min-height: 3.5em;

/* <percentage> value */
min-height: 10%;

/* Keyword values */
min-height: max-content;
min-height: min-content;
min-height: fit-content(20em);
