min-height

The min-height CSS property sets the minimum height of an element. It prevents the used value of the height property from becoming smaller than the value specified for min-height.

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);

/* Global values */
min-height: inherit;
min-height: initial;
min-height: unset;

Values

<length>
Defines the min-height as an absolute value.
<percentage>
Defines the min-height as a percentage of the containing block's height.
auto
The browser will calculate and select a min-height for the specified element.
none
No limit on the size of the box.
max-content

min-content
The intrinsic minimum min-height.
fit-content(<length-percentage>)
Uses the fit-content formula with the available space replaced by the specified argument, i.e. min(max-content, max(min-content, argument)).

Formal syntax

auto | <length> | <percentage> | min-content | max-content | fit-content(<length-percentage>)

where
<length-percentage> = <length> | <percentage>

Examples

table { min-height: 75%; }

form { min-height: 0; }
