The max-height CSS property sets the maximum height of an element. It prevents the used value of the height property from becoming larger than the value specified for max-height.

max-height overrides height, but min-height overrides max-height.

Syntax

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

/* <percentage> value */
max-height: 75%;

/* Keyword values */
max-height: none;
max-height: max-content;
max-height: min-content;
max-height: fit-content;
max-height: fill-available;

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

Values

<length>
The maximum height as an absolute value.
<percentage>
The maximum height, expressed as a percentage of the containing block's height.

Keyword values

none
The height has no maximum value.
max-content 
The intrinsic preferred height.
min-content 
The intrinsic minimum height.
fill-available 
The containing block's height minus the vertical margin, border, and padding. (Note that some browsers implement an ancient name for this keyword, available.)
fit-content 
The same as max-content.

Formal syntax

<length> | <percentage> | none | max-content | min-content | fit-content | fill-available

Examples

table { max-height: 75%; }

form { max-height: none; }

Accessibility concerns

Ensure that elements set with a max-height are not truncated and/or do not obscure other content when the page is zoomed to increase text size.
