The border-block-width
CSS property defines the width of the logical block borders of an element, which maps to a physical border width depending on the element's writing mode, directionality, and text orientation. It corresponds to the border-top-width
and border-bottom-width
, or border-left-width
, and border-right-width
property depending on the values defined for writing-mode
, direction
, and text-orientation
.
/* <'border-width'> values */ border-block-width: 5px; border-block-width: thick;
The border width in the other dimension can be set with border-inline-width
, which sets border-inline-start-width
, and border-inline-end-width
.
