/* Keyword value */ mask-border-repeat: stretch; mask-border-repeat: repeat; mask-border-repeat: round; mask-border-repeat: space; /* top and bottom | left and right */ mask-border-repeat: round stretch; /* Global values */ mask-border-repeat: inherit; mask-border-repeat: initial; mask-border-repeat: revert; mask-border-repeat: revert-layer; mask-border-repeat: unset;
The mask-border-repeat
property may be specified using one or two values chosen from the list of values below.
stretch
The source image's edge regions are stretched to fill the gap between each border.
repeat
The source image's edge regions are tiled (repeated) to fill the gap between each border. Tiles may be clipped to achieve the proper fit.
round
The source image's edge regions are tiled (repeated) to fill the gap between each border. Tiles may be stretched to achieve the proper fit.
space
The source image's edge regions are tiled (repeated) to fill the gap between each border. Extra space will be distributed in between tiles to achieve the proper fit.
Initial value | stretch |

This property doesn't appear to be supported anywhere yet. When it eventually starts to be supported, it will serve to define how the border mask slice will repeat around the border — i.e. will it just repeat, or be scaled slightly so a whole number of slices fits, or be stretched so one slice fits?
mask-border-repeat: round;
Chromium-based browsers support an outdated version of this property — mask-box-image-repeat
— with a prefix:
-webkit-mask-box-image-repeat: round;
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page features a working example (using the out-of-date prefixed border mask properties supported in Chromium), so you can get an idea of the effect.
