Definition and Usage
The border-block-style property sets the style of an element's borders in the block direction.
Values for the border-block-style property can be set in different ways:
If the border-block-style property has two values:
- border-block-style: dashed dotted;
- border style at block start is dashed
- border style at block end is dotted
If the border-block-style property has one value:
- border-block-style: dashed;
- border style at block start and end is dashed
The CSS
border-block-style property is very similar to CSS properties
border-bottom-style,
border-left-style,
border-right-style and
border-top-style, but the
border-block-style property is dependent on block direction.
Note: The related CSS property
writing-mode defines block direction. This affects where the start and end of a block is and the result of the border-block-style property. For pages in English, inline direction is left to right and block direction is downward.
