Description  

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