The min-block-size
CSS property defines the minimum horizontal or vertical size of an element's block, depending on its writing mode. It corresponds to either the min-width
or the min-height
property, depending on the value of writing-mode
.
If the writing mode is vertically oriented, the value of min-block-size
relates to the minimum width of the element; otherwise, it relates to the minimum height of the element. A related property is min-inline-size
, which defines the other dimension of the element.
