Values
<length>
Defines the max-height
as an absolute value.
<percentage>
Defines the max-height
as a percentage of the containing block's height.
none
No limit on the size of the box.
max-content
The intrinsic preferred max-height
.
min-content
The intrinsic minimum max-height
.
fit-content
Use the available space, but not more than max-content, i.e., min(max-content, max(min-content, stretch))
.
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))
.
stretch
Limits the maximum height of the element's margin box to the height of its containing block. It attempts to make the margin box fill the available space in the containing block, so in a way behaving similar to 100%
but applying the resulting size to the margin box rather than the box determined by box-sizing.
Note: To check aliases used by browsers for the stretch
value and its implementation status, see the Browser compatibility section.
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.
none
Applies to all elements but non-replaced inline elements, table columns, and column groups Inherited no Percentages The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the percentage value is treated as none
. Computed value the percentage as specified or the absolute length or none
