Why is CSS mask-image not working with no-repeat?


I have a SVG and I'd like to change its color to red on some event, but you can't do that with SVG as a background-image, so you have to use CSS image-mask. I'm using PHP to echo my CSS onto the style attribute of the div:

$jfid = "background-color:red;
        -webkit-mask-image:url(../like_icons/" . $iconfgg . ".svg);
         mask-image:url(../like_icons/" . $iconfgg . ".svg)"; 

Like

.buttonlikee {
    background: transparent;
    outline: none;
    border: none;
    margin-left: 10px;
    transition: 0.8s all ease
}
.ts{
  width: 34px;
  height: 32px;
  background-color:red;
  -webkit-mask-image:url(https://svgshare.com/i/CB7.svg);
  mask-image:url(https://svgshare.com/i/CB7.svg) 
}
<button class="buttonlikee">
  <div class="ts"></div>
</button>

This works as expected but returns a repeated image of the same SVG. So the solution would be to add no-repeat at last like this:

$jfid = "background-color:red;
         -webkit-mask-image:url(../like_icons/" . $iconfgg . ".svg) no-repeat;
         mask-image:url(../like_icons/" . $iconfgg . ".svg) no-repeat"; 

This in return gives me a div full of red color and you can't see the icon like

.buttonlikee {
    background: transparent;
    outline: none;
    border: none;
    margin-left: 10px;
    transition: 0.8s all ease
}
.ts{
  width: 34px;
  height: 32px;
  background-color:red;
  -webkit-mask-image:url(https://svgshare.com/i/CB7.svg) no-repeat;
  mask-image:url(https://svgshare.com/i/CB7.svg) no-repeat
}
<button class="buttonlikee">
  <div class="ts"></div>
</button>

Is this a bug? What could be the solution?


Solution

  • no-repeat is not a valid command for the mask-image property as seen in the documentation. Instead you should use the mask-repeat property like so:

    .buttonlikee {
        background: transparent;
        outline: none;
        border: none;
        margin-left: 10px;
        transition: 0.8s all ease
    }
    .ts {
      width: 34px;
      height: 32px;
      background-color:red;
      -webkit-mask-image: url(https://svgshare.com/i/CB7.svg);
      mask-image: url(https://svgshare.com/i/CB7.svg);
      -webkit-mask-repeat: no-repeat;
      mask-repeat: no-repeat;
    }
    <button class="buttonlikee">
      <div class="ts"></div>
    </button>

    Otherwise you can use the mask property shorthand:

    .buttonlikee {
        background: transparent;
        outline: none;
        border: none;
        margin-left: 10px;
        transition: 0.8s all ease
    }
    .ts {
      width: 34px;
      height: 32px;
      background-color:red;
      -webkit-mask: url(https://svgshare.com/i/CB7.svg) no-repeat;
      mask: url(https://svgshare.com/i/CB7.svg) no-repeat;
    }
    <button class="buttonlikee">
      <div class="ts"></div>
    </button>
