More Details for border-block
border-block
The border-block CSS property is a shorthand property for setting the individual logical block border property values in a single place in the style sheet.
border-block can be used to set the values for one or more of border-block-width, border-block-style, and border-block-color setting both the start and end in the block dimension at once. The physical borders to which it maps depends on the element's writing mode, directionality, and text orientation. It corresponds to the border-top and border-bottom or border-right, and border-left properties depending on the values defined for writing-mode, direction, and text-orientation.
The borders in the other dimension can be set with border-inline, which sets border-inline-start, and border-inline-end.
