Usage
Add bubbly to your webpage and call bubbly():
<body>
...
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/bubbly-bg.js"></script>
<script>bubbly();</script>
</body>Bubbly creates a canvas element and appends it to the body.
This element has position: fixed and z-index: -1, and always fills the
width/height of the viewport, which should make it plug and play for most projects.
You can also use bubbly with a canvas you create yourself,
by including {canvas: yourCanvas} in the configuration.
