Full-Screen Analytics Dashboard (100vh No-Scroll Engine)

The NOC-wall contract: every pixel of the viewport, zero scrollbars, ever. A dark command center where all four zones — status bar, KPI strip, chart grid, incident ticker — are fractional grid tracks that scale with the screen, type rides clamp() so it grows on a TV and shrinks on a laptop, and every panel is armored with minmax(0,1fr) + overflow guards so no runaway feed can ever summon the browser scrollbar. Live pulses, sweeping gauges and an equalizer chart make it feel like mission control; the geometry makes it kiosk-safe.

How this works

A no-scroll engine is a budget, spent top-down. The root claims the viewport and forbids overflow; rows divide it proportionally; every track is shrink-safe:

.center{ height:100%; overflow:hidden;   /* 100dvh in production */
  display:grid; gap:12px;
  grid-template-rows: 44px auto minmax(0,2.2fr) 36px;
}
.charts{ display:grid; min-height:0;
  grid-template-columns: repeat(3, minmax(0,1fr)); }
.panel{ min-height:0; overflow:hidden; }  /* the armor, every panel */

Two rules do the heavy lifting. fr units make zones proportional — on a 4K wall the chart row is huge, on a laptop it compresses, nothing overflows because nothing is fixed except the thin bars. And the minmax(0,…) / min-height:0 pair appears at EVERY level, because one track that refuses to shrink converts “scale down” into “overflow” — and the whole point is that overflow is banned.

Type joins the budget with viewport-relative clamps: font-size:clamp(22px, 3.2cqi + 8px, 54px) — container-query units so panels embedded anywhere still scale. The theatrics are compositor-cheap loops: gauge sweeps are a registered @property angle animating a conic-gradient, the equalizer is staggered scale:1 var(--s) keyframes, the ticker is one translate marquee that pauses on hover/focus and dies under reduced motion. In production swap the stage height for 100dvh — the dynamic unit that tracks mobile browser chrome — and pin overscroll-behavior:none on the body for kiosk builds.

Make it yours

  • Zone budget: the single grid-template-rows line — give charts more wall with 2.8fr.
  • Type ceiling: raise each clamp's max (54px → 80px) for 4K signage; the mins protect laptops.
  • Gauge values are one custom property each (--val:68) feeding both the conic fill and the label.
  • Ticker speed = distance/duration: the 26s token; halve for urgency. It duplicates its content once so the loop is seamless.

Gotchas — read before shipping

  • 100vh lies on mobile (browser chrome) — use 100dvh with a 100vh fallback line above it. On true kiosks either is fine.
  • Ban margins inside the engine: margins leak past track edges and are the usual culprit when a “perfectly budgeted” grid grows a 4px scrollbar. Gap + padding only, as here.
  • Infinite animations on a 24/7 wall are a GPU-budget item: everything here animates transform/opacity/custom-property angles (compositor-friendly), and prefers-reduced-motion stills all of it — test the wall build with it on.

@property gauges set the stated floor (Baseline July 2024); without them gauges render at their resting angle and everything else works from Chrome 111 / Safari 16.2 / Firefox 113. dvh units: Chrome 108 / Safari 15.4 / Firefox 101.
