min-height property

Definition and Usage

The min-height CSS property is used to set the minimum height of a given element. It prevents the used value of the height property from becoming smaller than the value specified for min-height.

The value of min-height overrides both max-height and height.

The containing block height minus horizontal margin, border and padding. Some browsers implement an ancient name for this keyword, available.
