CSS border-image-outset Property
The CSS border-image-outset property specifies the amount by which the border image is extended beyond the element’s border-box. It is one of the CSS3 properties. The border-image-outset property takes from one to four values.
- When one value is specified, it specifies all the four outlets.
- When two values are specified, the first one specifies the top and bottom outsets, and the second one specifies the right and left outsets.
- When three values are specified, the first one specifies the top outset, the second one specifies the right and left outsets, and the third one specifies the bottom outset.
- When four values are specified, the outsets are set on the top, right, bottom, and left sides in that order.
