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.

<rgba()> = rgba( <percentage>{3} [ / <alpha-value> ]? ) | rgba( <number>{3} [ / <alpha-value> ]? ) | rgba( <percentage>#{3} , <alpha-value>? ) | rgba( <number>#{3} , <alpha-value>? )
<hsl()> = hsl( <hue> <percentage> <percentage> [ / <alpha-value> ]? ) | hsl( <hue>, <percentage>, <percentage>, <alpha-value>? )
<hsla()> = hsla( <hue> <percentage> <percentage> [ / <alpha-value> ]? ) | hsla( <hue>, <percentage>, <percentage>, <alpha-value>? )
<hwb()> = hwb( [<hue> | none] [<percentage> | none] [<percentage> | none] [ / [<alpha-value> | none] ]? )
where 
<alpha-value> = <number> | <percentage>
<hue> = <number> | <angle>
