Backgrounds
Morphing Blob
Sky-blue-tan-gray conic-gradient blob slowly morphs its border-radius and spins behind a softly pulsing radial halo on a near-black background.

When to use it
Dark-mode hero backgrounds, loading screens, or ambient section dividers needing colorful organic motion without distraction.
When not to
Light-background layouts (background hardcoded near-black). Contexts where text legibility over the blob is required.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the accent colors to emerald/violet/orange by updating --accent-iris to #D8B297, --accent-cyan to #10b981, --accent-magenta to #f97316, and slow the morph cycle to 12s. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.
Safe to edit
- blob size (width:52%)
- morph cycle speed (8s)
- spin speed (14s)
- halo pulse speed (6s)
- conic-gradient color stops (--accent-iris, --accent-magenta, --accent-cyan)
- blur amount (blur(3px))
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- IIFE visibilitychange pause handler
- prefers-reduced-motion guard
- namespaced c09-morph class prefix
- will-change:border-radius,transform on blob
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Background color hardcoded in CSS variables — must update --bg-900 to use on non-dark pages
- No interactivity; purely decorative, aria-hidden=true
More Backgrounds components
- Aurora BorealisThree blurred, screen-blended gradient ribbons drift and skew over a near-black background, simulating northern lights in blush, cream, and rose.
- Mesh GradientFour blurred radial blobs in cream, gold, and tan drift and scale on a dark background with screen blend mode, creating a soft animated mesh gradient.
- Particle Constellation18–60 lilac/tan/mauve particles drift and bounce; nearby pairs connect with fading lines, forming a shifting constellation network on a dark background.
- Film GrainSVG feTurbulence noise jitters over a dark radial-tinted base with scrolling scanlines and a blinking magenta REC dot for an analog film look.
- Digital RainCyan katakana and hex glyphs fall in columns down a dark canvas, leaving fading trails; occasional bright white leading chars evoke the Matrix effect.
- Layered WavesThree SVG wave layers in iris, cyan, and dark slide horizontally at different speeds over a deep blue-gradient sky, creating a parallax depth effect.
