CSS border-image-slice Property

Example

Specify how to slice the border image:

#borderimg {
border-image-slice: 30%;
}

Definition and Usage

The border-image-slice property specifies how to slice the image specified by border-image-source. The image is always sliced into nine sections: four corners, four edges and the middle.

The "middle" part is treated as fully transparent, unless the fill keyword is set.

Tip: Also look at the border-image property (a shorthand property for setting all the border-image-* properties).
