Inherited: No
Computed value: The percentage as specified or the absolute length or 'none'
Animatable: Yes
JavaScript syntax: object.style.maxHeight

Interactive Demo

max-height: 150px;

max-height: 7em;

max-height: 20%;

max-height: 10px;

This is a box where you can change the maximum height.
This will limit how tall the box can be, potentially causing an overflow.

Syntax

max-height: [ [<length> | <percentage>] && [border-box | content-box]? ] | available | min-content | max-content | fit-content | none

Values

<length>Specifies a fixed width. Negative values are not allowed.
<percentage>A percentage relative to the width of the containing block. If the containing block has no width explicitly set then is is treated as none. Negative values are not allowed.
max-contentThe max-content width or height.
min-contentThe min-content width or height.
availableThe containing block width or height minus margin, border, and padding.
fit-contentIf the total available space is finite, equals to min(max-content, max(min-content, fill-available)). Otherwise, equal to the max-content measure. Requires CSS Intrinsic & Extrinsic Sizing Module support in browsers.
noneThe width has no maximum value.
