Fibre Patch Panel

Four dark fibre channels between lit ports, each carrying a bright packet of light from the source port to the far one, which flares white as the packet lands.

What do I do with this?

  1. Put fibre-patch-panel-15753.css anywhere your page already loads CSS from — in Next.js that is app/globals.css, or any stylesheet with a <link> in your HTML.
  2. Then put the class on the element you want it on: <button class="fx-v14-gl-fibre-15752">. The CSS does nothing until a class name in it matches something on the page.
  • Link the stylesheet, then paste the markup wherever you need it.
npx hoverlab add fibre-patch-panel-15753

License

Free to read, copy and install, for personal and non-commercial projects. Shipping it in client work or a paid product needs Pro ($79 once). The source lands in your repo and stops being ours — no attribution, nothing to upgrade.

Was this useful?

Motion safety

Static estimate, read from the CSS

Reduced motion
Guarded

Ships a prefers-reduced-motion block, so the loop settles into its end state for visitors who ask for less motion.

What it animates
Reflows

Animates left (and background, box-shadow). The browser re-lays-out the page on every frame; prefer transform if you can.

Flashing (WCAG 2.3.1)
Under 3 flashes/s

Its brightest loop is about 0.4 a second. Estimated from duration, iterations and keyframes, not from rendered frames.

Layout shift (CLS)
May shift layout

Animates left on a box in flow, so content beside or after it can move. A category from the CSS, not a measurement for this effect.

Every row is read from the shipped CSS. Only a figure marked measured came from a browser. Customizing the speed changes the timing, so recheck a customized copy. How it is computed
