border-image-source

{{CSSRef}}

The border-image-source CSS property sets the source image used to create an element’s border image.

{{InteractiveExample("CSS Demo: border-image-source")}}

border-image-source: url("/shared-assets/images/examples/border-diamonds.png");

border-image-source: url("/shared-assets/images/examples/border-stars.png");

border-image-source: repeating-linear-gradient(
  45deg,
  transparent,
  #4d9f0c 20px
);

border-image-source: none;

<section id="default-example">
  <div id="example-element">This is a box with a border around it.</div>
</section>

#example-element {
  width: 80%;
  height: 80%;
  display: flex;
  align-items: center;
  justify-content: center;
  padding: 50px;
  background: #fff3d4;
  color: #000;
  border: 30px solid;
  border-image: url("/shared-assets/images/examples/border-diamonds.png") 30
    round;
  font-size: 1.2em;
}

The {{cssxref("border-image-slice")}} property is used to divide the source image into regions, which are then dynamically applied to the final border image.
