Glitch Arcade

Cyber-arcade split — deep purple base with neon-green and magenta. Continuous glitch overlay shifts the colored layers in/out across the seam. Different from Tokyo Neon (sidebars): this is dystopian-arcade not tokyo-pop, dark green vs hot magenta.

How this works

The wrapper applies filter: contrast(1.1) saturate(1.2) and a full-panel repeating-linear-gradient at 0.06 opacity for CRT scanlines. Inside, grid-template-columns: 1fr 1fr hosts two player stat blocks. The glitch header is one element with the label as content and two text-shadow layers — 2px 0 #ff2e63 (red channel) and -2px 0 #08f7fe (cyan channel) — creating the RGB split without duplicated DOM. Stat rows use display: grid; grid-template-columns: 1fr auto with a dotted border-bottom, and health bars are <div>s with a fixed track and an inner width-driven fill using accent gradients.

Make it yours

  • Increase the RGB split by pushing text-shadow offsets to 3px/-3px and adding a third yellow layer at 0 2px #f9f871 for a heavier chromatic aberration effect.
  • Swap accents per player by scoping --accent on each panel — player 1 #ff2e63, player 2 #08f7fe — and referencing it in the health-bar fill gradient.
  • Add scanline motion with a @keyframes that animates the scanline gradient's background-position-y; keep speed under 4s or it becomes a strobe.
  • Replace pixel fonts with Press Start 2P or VT323 for a fuller arcade feel; drop letter-spacing to 0 because those fonts already carry chunky spacing.

Gotchas — read before shipping

  • The wrapper filter creates a new stacking context, so tooltips, dropdowns, or modals inside will not escape the panel — hoist any overlay to a portal outside the wrapper.
  • RGB-split text-shadow harms legibility at small sizes; keep the effect on headers 24px+ and use a plain shadow (or none) on body copy and stat values.
  • Any scanline animation must be gated behind @media (prefers-reduced-motion: reduce) — the flicker is a documented migraine and vestibular trigger, not a stylistic preference.
