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.

Syntax

/* no border-image, use the specified border-style */
border-image-source: none;

/* the image.jpg is used as image */
border-image-source: url(image.jpg);

/* a gradient is used as image */
border-image-source: linear-gradient(to top, red, yellow);

/* Global values */
border-image-source: inherit;
border-image-source: initial;
border-image-source: unset;

Values

none

Specifies that no image should be used for the border. Instead the style defined by border-style is used.

<image>
