Note: This property specifies the inward offsets from the top, right, bottom, and left edges of the image, dividing it into nine regions: four corners, four edges and a middle. The middle image part is discarded (treated as fully transparent) unless the fill keyword is present. If the fourth number/percentage is omitted, it is the same as the second. If the third one is also omitted, it is the same as the first. If the second one is also omitted, it is the same as the first.
