border-image-source

Summary

The border-image-source CSS property defines the <image> to use instead of the style of the border. If this property is set to none, the style defined by border-style is used instead.

Note: Though any <image> can be used with this CSS property, browser support is still limited and some browsers support only images defined using the url() functional notation.
