The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

border-image-slice property is used to divide the source image into regions, which are then dynamically applied to the final border image.

句法

/* Keyword value */
border-image-source: none;
/* <image> values */
border-image-source: url(image.jpg);
border-image-source: linear-gradient(to top, red, yellow);
/* Global values */
border-image-source: inherit;
border-image-source: initial;
border-image-source: unset;

值

none: No border image is used. The appearance defined by border-style is displayed instead.
<image>
