Ocean Light Cone
Glow & Neon

Ocean Light Cone

Volumetric beam as a blurred trapezoid between an emitter and the ellipse it lands on, all three flickering together so the shaft and its pool stay tied.

What do I do with this?

  1. Put ocean-light-cone-14251.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-v10-glow-lightcone-ocean-14250">. 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.

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
Compositor only

Only transform, opacity or filter: the GPU can run it without re-laying-out or repainting the page.

Flashing (WCAG 2.3.1)
Under 3 flashes/s

Its brightest loop is about 0.2 a second. Estimated from duration, iterations and keyframes, not from rendered frames.

Layout shift (CLS)
No shift expected

Nothing it animates moves or resizes the box in flow. 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
