border-block-style

The border-block-style CSS property defines the style of the logical block borders of an element, which maps to a physical border style depending on the element’s writing mode, directionality, and text orientation. It corresponds to the border-top-style and border-bottom-style, or border-left-style and border-right-style properties depending on the values defined for writing-mode, direction, and text-orientation.

The border style in the other dimension can be set with border-inline-style, which sets border-inline-start-style, and border-inline-end-style.

Values: <line-style> The line style of the border. See border-style.

Syntax example: border-block-style: dashed;
