How this works

The tube itself is the double-background border trick (padding-box near-black fill, border-box magenta→cyan gradient ring) with the label glowing via stacked text-shadows at 10px and 30px radii. The neon light comes from both pseudo-elements carrying the same gradient at inset: -2px: ::before blurred 14px as the tight halo hugging the glass, ::after blurred 46px at lower opacity as the room-filling wash.

Each layer runs the same gb-11-breathe keyframe — opacity .35↔.8 with a hair of scale — but ::after starts at -1.3s, half a cycle out of phase. The two glows therefore pulse alternately rather than together, which is what makes it read as live electrified gas instead of a simple fade loop. Hover intensifies both layers and stretches letter-spacing from 5px to 7px.

Make it yours

  • Neon color is two edits: the --neon-b/--neon-c pair feeds the ring, both glow layers and the sign accent simultaneously.
  • Make the tube feel higher-voltage by shortening the breathe cycle below 2s and raising the peak opacity of ::before toward 1.
  • The background's faint 34px grid is two 1px repeating gradients — resize or delete it without touching the button.
  • Monospace + wide letter-spacing carries the arcade voice; on hover the tracking stretch is the micro-interaction, so keep the .3s ease on it.
  • For a flickering-broken-tube variant, add a steps() keyframe that drops ::before opacity to .1 for a single frame every few seconds.

Gotchas — read before shipping

  • Two large-radius blurs animating simultaneously is real GPU work — this is a hero-element treatment, not something to tile twenty times in a grid.
  • The negative-phase trick requires a negative animation-delay (-1.3s), not a positive one — positive delay would leave the wash unlit for the first 1.3 seconds.
  • Blurred pseudo-elements at z-index: -1 disappear if any ancestor traps them in a stacking context with an opaque background; keep the button's parent transparent.
