1. Load the Worklet

Using CDN is the easiest way to add this Worklet:

if ('paintWorklet' in CSS) {
  CSS.paintWorklet.addModule('https://unpkg.com/@houdini-css-paint/depth-spiral/index.js');
}

2. Polyfill

To add support for all modern browsers, you can load the worklet with css-paint-polyfill fallback.

<script>
  ;(async function() {
    if (CSS['paintWorklet'] === undefined)
      await import('https://unpkg.com/css-paint-polyfill')

    CSS.paintWorklet.addModule('https://unpkg.com/@houdini-css-paint/depth-spiral/index.js')
  })()
</script>

3. Using the Paintlet

To use this Paintlet after you have succesffuly loaded it, you need to add background(-image): paint(depth-spiral) to any HTML element on your page. You can control its appearance just like any other regular image referenced in CSS with properties such as background-size, background-repeat, background-position and so on.

.my-element {
  --depth-spiral-min-radius: 10%;
  --depth-spiral-max-radius: 100%;
  --depth-spiral-num-points: 200;
  --depth-spiral-angle: 183deg;
  --depth-spiral-line-width: 1;
  --depth-spiral-color: #aaaaaa;

  background-image: paint(depth-spiral);
}
