The border-image CSS property lets you draw an image as the border around an element. It’s a shorthand property for setting border-image-source, border-image-slice, border-image-width, border-image-outset, and border-image-repeat. For instance, to use an image as a border, you could use: border-image: url(border.png) 30 round;, where border.png is your image source, 30 is the slice, and round is the repeat method.
