[SOLVED] Animated SVG border-image not honoring border-radius

Animated SVG border-image not honoring border-radius

I'm trying to make an animated border radius via using an SVG with border-image, and round it out with border-radius. I have overflow: hidden; but the border doesn't seem to be affected by this property. I'll give the current code below, and an example of the border styles in a JSFiddle. Any help is appreciated!

    margin: 0 auto;
    height: 80vh;
    font-size: 3vw;
    overflow: hidden;
    border: 5px solid;
    border-image: url(../images/borderAnimation.svg) 5 stretch;
    border-radius: 15px;
    background-color: rgb(70, 70, 70);

Solution

I know this is kind of cheating, but if you could have nested elements then the parent could have a background and the child could mask of the background with a color:

div.wrapper {
  width: 300px;
  height: 200px;
  border-radius: 10px;
  padding: 5px;
  background-image: url('data:image/svg+xml;base64,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');
  background-repeat: no-repeat;
  background-size: cover;
  display: flex;
  align-items: center;
  justify-content: center;
}

div.wrapper>div {
  width: 100%;
  height: 100%;
  border-radius: 5px;
  box-sizing: border-box;
  background: white;
}

<div class="wrapper">
  <div></div>
</div>

The SVG for the background:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 300 200">
  <defs>
    <linearGradient id="lg1">
      <stop offset="0" stop-color="orange" />
      <stop offset="1" stop-color="navy" />
    </linearGradient>
  </defs>
  <g transform="translate(150 100)">
    <circle r="200" fill="url(#lg1)">
      <animateTransform attributeName="transform" attributeType="XML"
      type="rotate" from="0" to="360" dur="5s" repeatCount="indefinite" />
    </circle>
  </g>    
</svg>
