        | min-height - space for scrollbar 
            Any space taken up by the scrollbars should be taken out of (subtracted from the dimensions of) the containing block formed by the element with the scrollbars. | A | 
      
        | min-height - float and overflow 
            'min-height' specifies a fixed minimum used height.
