CSS Property: border-image-width

Border image drawing area. The width within a border that an image is painted in.

Set by establishing inner-offsets from the top, right, bottom, and left edges of a border. If the border’s image width is wider than the border’s width (set by border-width), the border image will spill over the border’s boundary and leak into the box’s padding and content areas.
