border-image-slice

Determines how to 'cut' the border image into nine pieces (four corners, four edges, and a center). These pieces are then used to build the final border by resizing them to fit your element.

Quick example

.sliced-box {
  border: 30px solid;
  border-image-source: url('border.png');
  /* Cut 30px from each edge of the image source */
  border-image-slice: 30;
}
