How this works

The horizontal step track marks status via .done, .active, .pending classes. Completed circles pulse via kf-29-nodeshine animating box-shadow: 0 0 0 0 → 0 0 0 8px transparent, creating an expanding ripple. The active step adds a second border-colour swap (#7c6af7 → #a898fc) plus its own shadow pulse. The active connector line animates width: 30% → 85% with ease-in-out alternate for a progressing-flow look.

The radial steps use SVG circles with stroke-dasharray: 220; stroke-dashoffset: 0/55/110/165 for 0%/25%/50%/75% progress. Each runs a tiny ±10 dashoffset wobble for subtle life. The morphing pill row scales completed pills slightly, scales the active pill larger with a swelling shadow pulse, and fades pending pills' opacity. The vertical timeline reuses the same pulse pattern on dot nodes with a gradient connector.

Make it yours

  • Change progress by swapping which steps have .done vs .active vs .pending class names.
  • Recolour the active accent via the #7c6af7 hex used in .step-node.done, .active, and SVG strokes.
  • Slow the pulse cadence by changing kf-29-nodeshine from 3s to 5s for less attention-grabbing motion.
  • Adjust the radial fill ratio by editing the stroke-dashoffset initial value — lower numbers = fuller arc.
  • Tighten the pill row by reducing the gap from 8px to 4px for denser progress indicators.

Gotchas — read before shipping

  • stroke-dasharray: 220 assumes a circle with r=35 — different radii need recalculation: 2 * π * r.
  • The active line's width animation hits layout — for many concurrent step trackers, replace with transform: scaleX() and transform-origin: left.
  • Pulse box-shadow animations are paint-heavy — fine for one progress tracker, expensive in a list of 20 onboarding cards.
