The border-image-width
CSS property sets the width of an element's border image.
If this property's value is greater than the element's border-width
, the border image will extend beyond the padding (and/or content) edge.
/* Keyword value */ border-image-width: auto; /* <length> value */ border-image-width: 1rem; /* <percentage> value */ border-image-width: 25%; /* <number> value */ border-image-width: 3; /* top and bottom | left and right */ border-image-width: 2em 3em; /* top | left and right | bottom */ border-image-width: 5% 15% 10%; /* top | right | bottom | left */ border-image-width: 5% 2em 10% auto; /* Global values */ border-image-width: inherit; border-image-width: initial; border-image-width: revert; border-image-width: revert-layer; border-image-width: unset;
The border-image-width
property may be specified using one, two, three, or four values chosen from the list of values below.
<length-percentage>
The width of the border, specified as a <length>
or a <percentage>
. Percentages are relative to the width of the border image area for horizontal offsets and the height of the border image area for vertical offsets. Must not be negative.
<number>
The width of the border, specified as a multiple of the corresponding border-width
. Must not be negative.
auto
The width of the border is made equal to the intrinsic width or height (whichever is applicable) of the corresponding border-image-slice
. If the image does not have the required intrinsic dimension, the corresponding border-width
is used instead.

border-image-width =
[ <length-percentage [0,∞]> | <number [0,∞]> | auto ]{1,4}
<length-percentage> =
<length> |
<percentage>
This example creates a border image using the following ".png" file, which is 90 by 90 pixels:
Thus, each circle in the source image is 30 by 30 pixels.
