Replicating an svg animation

When this site first loads there’s this animation where there’s a triangle that traces over another triangle.

How would I replicate the same thing?

Where the triangle traces over the other triangle.

Can someone provide a jsfiddle of how it's done.

I found this from the site, but I don't know how to put it together.

<svg xmlns="http://www.w3.org/2000/svg" width="80" height="80" viewBox="0 0 47.96 51.66">

.cls-1{fill:none;stroke:#fff;stroke-miterlimit:10;stroke-width:4px;}</style>

Solution

  • It is just using the common line drawing technique of animating the stroke-dashoffset. The bit you were missing was the @keyframes` definition(s).

    .logo-load_w svg path {
  stroke: #08f9ff;
  stroke-dasharray: 150;
  stroke-dashoffset: 1500;
  -webkit-animation: draw 20s infinite linear;
  animation: draw 20s infinite linear;
}

@-webkit-keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}

@keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}
    <div class="logo-load_w">
  <svg xmlns="http://www.w3.org/2000/svg" width="80" height="80" viewBox="0 0 47.96 51.66"><defs><style>.cls-1{fill:none;stroke:#fff;stroke-miterlimit:10;stroke-width:4px;}</style></defs><g id="Слой_2" data-name="Слой 2"><g id="play"><path class="cls-1" d="M2,25.83V4.11A2.11,2.11,0,0,1,5.13,2.27L44.88,24.45a2.11,2.11,0,0,1,0,3.7L5.1,49.41A2.11,2.11,0,0,1,2,47.55V25.83"></path></g></g></svg>
</div>

    The dark triangle in the background is just a second copy of the SVG, with the stroke colour set to a different colour.

    Update

    The simplest way to have a darker triangle behind the blue one, is not the way the original site does it. It is easier just to add a second copy of the triangle into the SVG. You put it earlier in the SVG, so that it is drawn first. And make its stroke colour black.

    .logo-load_w svg .play {
  stroke: #08f9ff;
  stroke-dasharray: 150;
  stroke-dashoffset: 1500;
  -webkit-animation: draw 20s infinite linear;
  animation: draw 20s infinite linear;
}

@-webkit-keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}

@keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}
