Bubbly-bg is a lightweight JavaScript library for creating animated bubble backgrounds on web pages. It renders the effect on an HTML canvas and can automatically create and position that canvas behind page content. Developers can control background colors or gradients, bubble count, size, fill, direction, speed, shadows, and strokes. Animation can be enabled or disabled, and a custom canvas can be supplied when needed.
