The mask-repeat
CSS property sets how mask images are repeated. A mask image can be repeated along the horizontal axis, the vertical axis, both axes, or not repeated at all.
/* One-value syntax */ mask-repeat: repeat-x; mask-repeat: repeat-y; mask-repeat: repeat; mask-repeat: space; mask-repeat: round; mask-repeat: no-repeat; /* Two-value syntax: horizontal | vertical */ mask-repeat: repeat space; mask-repeat: repeat repeat; mask-repeat: round space; mask-repeat: no-repeat round; /* Multiple values */ mask-repeat: space round, no-repeat; mask-repeat: round repeat, space, repeat-x; /* Global values */ mask-repeat: inherit; mask-repeat: initial; mask-repeat: unset;
By default, the repeated images are clipped to the size of the element, but they can be scaled to fit (using round
) or evenly distributed from end to end (using space
).
Syntax
One or more <repeat-style>
values, separated by commas.
Values
<repeat-style>
- The one-value syntax is a shorthand for the full two-value syntax:
-
Single value Two-value equivalent repeat-x
repeat no-repeat
repeat-y
no-repeat repeat

repeat
The image is repeated as much as needed to cover the whole mask painting area. The last image will be clipped if it doesn't fit. space
The image is repeated as much as possible without clipping. The first and last images are pinned to either side of the element, and whitespace is distributed evenly between the images. The mask-position
property is ignored unless only one image can be displayed without clipping. The only case where clipping happens usingspace
is when there isn't enough room to display one image.round
As the allowed space increases in size, the repeated images will stretch (leaving no gaps) until there is room for another one to be added. When the next image is added, all of the current ones compress to allow room. Example: An image with an original width of 260px, repeated three times, might stretch until each repetition is 300px wide, and then another image will be added. They will then compress to 225px. no-repeat
The image is not repeated (and hence the mask painting area will not necessarily be entirely covered). The position of the non-repeated mask image is defined by the mask-position
CSS property.
Formal definition
Initial value | no-repeat |

Applies to | all elements; In SVG, it applies to container elements excluding the defs element and all graphics elements |
Inherited | no |
Computed value | Consists of two keywords, one per dimension |
Animation type | discrete |
Formal syntax
<repeat-style>#where
<repeat-style> = repeat-x | repeat-y | [ repeat | space | round | no-repeat ]{1,2}
Examples
Setting repeat for a single mask
CSS
#masked { width: 250px; height: 250px; background: blue linear-gradient(red, blue); mask-image: url(https://mdn.mozillademos.org/files/12676/star.svg); mask-repeat: repeat; /* Can be changed in the live sample */ margin-bottom: 10px; }
HTML Content
<div id="masked"> </div> <select id="repetition"> <option value="repeat-x">repeat-x</option> <option value="repeat-y">repeat-y</option> <option value="repeat" selected>repeat</option> <option value="space">space</option> <option value="round">round</option> <option value="no-repeat">no-repeat</option> </select>
JavaScript Content
var repetition = document.getElementById("repetition"); repetition.addEventListener("change", function (evt) { document.getElementById("masked").style.maskRepeat = evt.target.value; });
Result
Multiple mask image support
You can specify a different <repeat-style>
for each mask image, separated by commas:
.examplethree { mask-image: url('mask1.png'), url('mask2.png'); mask-repeat: repeat-x, repeat-y; }
Each image is matched with the corresponding repeat style, from first specified to last.
