More Details for mask-border-source
mask-border-source
The mask-border-source
CSS property sets the source image used to create an element's mask border.
The mask-border-slice
property is used to divide the source image into regions, which are then dynamically applied to the final mask border.
Syntax
/* Keyword value */ mask-border-source: none; /* <image> values */ mask-border-source: url(image.jpg); mask-border-source: linear-gradient(to top, red, yellow); /* Global values */ mask-border-source: inherit; mask-border-source: initial; mask-border-source: revert; mask-border-source: unset;

Examples
Basic usage
This property doesn't appear to be supported anywhere yet. When it eventually starts to be supported, it will serve to define the source of the border mask.
mask-border-source: url(image.jpg);
Chromium-based browsers support an outdated version of this property — mask-box-image-source
— with a prefix:
-webkit-mask-box-image-source: url(image.jpg);
Note: The mask-border
page features a working example (using the out-of-date prefixed border mask properties supported in Chromium), so you can get an idea of the effect.
