When to use it
Loading states, processing indicators, or ambient backgrounds where a looping radial pulse fits the brand (dark-mode, tech, neon themes).
When not to
Light backgrounds (hardcoded dark body color). Contexts requiring a determinate progress indicator — this communicates indeterminate loading only.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the accent colors: set --accent-cyan to #00ff99 and --accent-magenta to #ff9900, then slow the ripple cycle to 3.6s by editing animation-duration on .c07-ripple__wave. 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
- ripple cycle duration (2.6s in animation shorthand)
- ring colors (--accent-iris, --accent-cyan, --accent-magenta)
- core size (13% width/height)
- stagger delay between waves (.65s increments)
- core glow spread (box-shadow 24px)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- visibilitychange pause in IIFE
- prefers-reduced-motion guard
- role=img + aria-label on wrapper
- nth-child stagger delays
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Light re-theme via the [data-theme=light] token block; catalog bg/accent describe the dark default
- Purely decorative; does not communicate actual load progress

- Morphing BlobAurora-gradient blob slowly morphs border-radius and rotates, with an inset dark ghost layer counter-rotating. Soft glow on dark backdrop.
- DNA HelixTwo columns of 10 glowing dots swing left-right in opposite phases, tracing a rotating DNA double helix. Cycling status messages fade in below.
- Skeleton ShimmerDark content-placeholder card with avatar circle and staggered text bars swept by a looping gold-to-tan shimmer gradient. Pure CSS, no JS logic.
- Particle Orbit18 glowing iris, cyan, and magenta particles orbit a white core on wobbling elliptical paths; trailing fill creates a comet-like motion blur effect.
- Equalizer BarsSeven pill-shaped vermillion-to-tan gradient bars bounce at staggered offsets, mimicking an audio equalizer. Pure CSS scaleY animation.
- Conic ProgressA circular conic-gradient ring fills from 0–100% with a lime arc and a blurred gold glow layer; a live numeric counter updates in sync.
