A CSS Houdini Worklet to paint HSL powered background noise.
Using CDN is the easiest way to add the library:
if ('paintWorklet' in CSS) {
CSS.paintWorklet.addModule('https://unpkg.com/houdini-noise/dist/worklet.js');
}To add support for all moder 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-noise/dist/worklet.js');
})()
</script>To use Noise worklet you need define some custom properties with values and add the value paint(noise) on background property.

--noise: 0; /* Entry point to animate noise */
