How this works

A 54×26 void-dark track with a 30%-alpha cyan border idles dim; checking it drives the border to 90% alpha and adds a dual glow — 12px outer bloom plus an 8px inset wash — so the tube ignites from both sides of the glass. The 18px thumb is a radial-gradient orb with its own glow that intensifies from 6px to 14px as it slides.

All neon is layered box-shadow at graded alphas of one hue, so the entire demo rehues by changing the rgba stops. Monospace uppercase labeling does the cyberpunk typography work.

Make it yours

  • Rehue by swapping the rgba(0,220,255) stops — magenta and acid green both work.
  • Add an idle flicker keyframe on the border for a failing-tube vibe (gate behind prefers-reduced-motion).
  • Thicken the border to 2px for stronger tube presence at larger sizes.
  • Pair states: dim magenta off / cyan on, as in demo 16.

Gotchas — read before shipping

  • Glow only reads on dark grounds — below ~15% background lightness.
  • The thumb slides via left here; swap to transform:translateX for strict INP budgets.
  • Keep at least the border-color change alongside glow — glow alone can vanish on low-quality displays.
