border-image-repeat

The border-image-repeat CSS property defines how the middle part of a border image is handled so that it can match the size of the border. It has a one-value syntax that describes the behavior of all the sides, and a two-value syntax that sets a different value for the horizontal and vertical behavior.

Initial value	`stretch`
Applies to	all elements, except internal table elements when `border-collapse` is `collapse`. It also applies to `::first-letter`.
Inherited	no
Media	visual
Computed value	as specified
Animation type	discrete
Canonical order	the unique non-ambiguous order defined by the formal grammar

Syntax

/* border-image-repeat: type */
border-image-repeat: stretch;

/* border-image-repeat: horizontal vertical */
border-image-repeat: round stretch;

/* Global values */
border-image-repeat: inherit;
border-image-repeat: initial;
border-image-repeat: unset;

Values

type: One of the stretch, repeat, or round keywords denoting how the image is treated both horizontally and vertically.
horizontal: One of the stretch, repeat, or round keywords denoting how the image is treated horizontally.
vertical: One of the stretch, repeat, or round keywords denoting how the image is treated vertically.
stretch: Keyword indicating that the image must be stretched to fill the gap between the two borders.
repeat: Keyword indicating that the image must be repeated until it fills the gap between the two borders.
round: Keyword indicating that the image must be repeated until it fills the gap between the two borders. If the image doesn't fit after being repeated for an integral number of times, the image is rescaled to fit.
space: The image is tiled (repeated) to fill the area. If it does not fill the area with a whole number of tiles, the extra space is distributed around the tiles.

Formal syntax

[ stretch | repeat | round | space ]{1,2}
