Floating Card Shadow CSS Breadcrumb Navigation

Each crumb is an elevated white card floating over the surface with a soft layered shadow, connected by faint dotted trails — a clear, tactile step-by-step path where every node reads as a distinct, liftable card. Hover raises the card higher; the current card rests at the top elevation.

## JavaScript
```js
/* No JavaScript — each crumb is an elevated card with a two-layer (ambient+key) shadow; hover lifts with translateY + deeper shadow, the current page rests at top elevation. */
```

How this works

Each crumb is a small card: white fill, rounded corners, and a two-layer soft shadow (a tight ambient layer plus a wider, softer key-light layer) — the modern 'realistic elevation' recipe rather than a single hard shadow. Between cards, a faint dotted connector (li + li::before with a repeating-linear-gradient or a dotted border) traces the path without competing with the cards. The layout is flex with gap, so cards keep even spacing and wrap as tidy rows.

Elevation encodes state: at rest cards sit at elevation 1; on :hover/:focus-visible the card lifts with a translateY(-2px) and a deeper shadow (elevation 3), giving a physical 'pick up' feel; the current page rests permanently at the highest elevation with an accent-tinted edge, so 'you are here' reads as the raised card. The two-layer shadow scaling with elevation is what makes the lift feel real rather than a flat colour change.

Make it yours

  • Elevation scale: define 3 shadow presets (rest/hover/current) as tokens and swap between them — matches Material/Fluent elevation systems.
  • Connector style: dotted, dashed, or a thin solid line — set on the ::before; drop it for pure floating cards.
  • Add a leading icon per card for a richer node; the card padding accommodates it.
  • Warm the shadows with a slight hue (not pure black) for a softer, more designed feel.

Gotchas — read before shipping

  • Use two stacked shadows (ambient + key) — a single large soft shadow looks like a blurry glow, not elevation.
  • Animate transform + box-shadow only; never animate top/margin for the lift (layout thrash).
  • Keep the connector behind the cards (z-index) and pointer-events:none so it never blocks a card click.
  • Don't over-elevate — cards that lift too far on hover feel jumpy; 2px + a modest shadow bump is enough.

Floor set by oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome all.

Multi-layer box-shadow, transform and flex gap are universally supported. Nothing bleeding-edge; works on any production site.
