CSS - border-inline

The CSS property border-inline is a shorthand property that sets the values for different logical inline border attributes, combining them into a single statement.

The writing mode, directionality, and text orientation of the element determine how the border-inline attribute is mapped to actual boundaries.
Depending on values of writing-mode, direction, and text-orientation, border-inline behaves as either border-top and border-bottom or border-right and border-left properties.
Use the border-block property, which sets both border-block-start and border-block-end, to establish borders in other dimension.

Possible values

The border-inline is specified with one or more of the following, in any order:

<'border-width'> - The width of the border.
<'border-style'> - The line style of the border.
<color> - The color of the border.

Constituent properties
