Definition and Usage
The border-block-start-style
property sets the style of an element's border at the start in the block direction.
The CSS
border-block-start-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-start-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-start-style
property. For pages in English, inline direction is left to right and block direction is downward.
