Usage

Add bubbly to your webpage and call bubbly():

<body>
  ...
  <script src="https://cdn.jsdelivr.net/npm/bubbly-bg@0.2.3/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.
