The border-block-end CSS property is a shorthand property for setting the individual logical block-end border property values in a single place in the style sheet.
Constituent properties
This property is a shorthand for the following CSS properties:
Syntax
border-block-end: 1px; border-block-end: 2px dotted; border-block-end: medium dashed blue; /* Global values */ border-block-end: inherit; border-block-end: initial; border-block-end: revert; border-block-end: revert-layer; border-block-end: unset;
border-block-end can be used to set the values for one or more of border-block-end-width, border-block-end-style, and border-block-end-color. The physical border to which it maps depends on the element's writing mode, directionality, and text orientation. It corresponds to the border-top, border-right, border-bottom, or border-left property depending on the values defined for writing-mode, direction, and text-orientation.
Related properties are border-block-start, border-inline-start, and border-inline-end, which define the other borders of the element.
Values
The border-block-end is specified with one or more of the following, in any order:
<'border-width'>- 
    
The width of the border. See
border-width. <'border-style'>-
