border-block-end 属性是一个简写属性，用于在样式表中的单个位置设置各个逻辑块结尾边界属性值。

Syntax

border-block-end: 1px;
border-block-end: 2px dotted;
border-block-end: medium dashed blue;

border-block-end can be used to set the values for one or more of border-block-end-width (en-US), border-block-end-style (en-US), and border-block-end-color (en-US). 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 (en-US), border-inline-start (en-US), and border-inline-end (en-US), which define the other borders of the element.
