CSS min-height Property

❮ Prev Next ❯

The min-height property sets an element's minimum height. This property prevents the height property's value from becoming smaller than the value specified for min-height.

The min-height property overrides the max-height and height properties.

The property takes a CSS length (px, pt, em, etc.) or a percentage.

Negative values are not accepted.
