max-height property CSS Reference

Definition and Usage

The max-height CSS property is used to set the maximum height of a given 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.

  • Initial 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.
  • Media visual
  • Computed Value the percentage as specified or the absolute length or none
  • Animatable yes, as a length, percentage or calc(); when both values are lengths, they are interpolated as lengths; when both values are percentages, they are interpolated as percentages; otherwise, both values are converted into a calc() function that is the sum of a length and a percentage (each possibly zero), and these calc() functions have each half interpolated as real numbers.
  • Canonical order the unique non-ambiguous order defined by the formal grammar


Formal syntax: <length> | <percentage> | none | max-content | min-content | fit-content | fill-available
max-height: 3.5em
max-height: 75%
max-height: none
max-height: max-content
max-height: min-content
max-height: fit-content
max-height: fill-available
max-height: inherit
