Tailwind Image Ripple Animation Hover

Three concentric rings pulse outward on hover. The port makes two changes on the way: the keyframe becomes an --animate-tih15-ripple token (so group-hover:animate-tih15-ripple is a real utility), and the rings expand with scale instead of width/height — the fix the CSS version lists as a customization, taken as the default.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • --animate-tih15-ripple in @theme mints animate-tih15-ripple, so the markup states which animation runs and when — the keyframe body stays in CSS, which is correct.
  • The keyframe is rewritten to animate scale rather than width/height/top/left. The CSS collection lists that as a suggested improvement; the port ships it.
  • Three :nth-child delay rules become one [animation-delay:calc(var(--i)*0.5s)] utility plus an index per ring.
  • Three per-item ring-colour rules become an inline --ring and a border-[var(--ring)] utility shared by all nine rings.
  • group-hover:animate-tih15-ripple keeps the animation non-existent at rest — the same optimisation the CSS version makes with animation:none, now legible on the element.
  • The social spans become real <a> elements with labels and focus rings. A hover-revealed row of unlabelled glyphs is not reachable, and utilities made adding the states cheap.

## CSS
```css
@import "tailwindcss";

@theme {
  --color-tih15-bg: #060d0d;
  --color-tih15-bg: oklch(0.11 0.012 190);
  --color-tih15-text: #f1f5f9;
  --color-tih15-text: oklch(0.96 0.005 250);
  --color-tih15-muted: #64748b;
  --color-tih15-muted: oklch(0.58 0.035 255);
  --color-tih15-acc: #2dd4bf;
  --color-tih15-acc: oklch(0.8 0.13 185);
  --font-tih15-sans: 'Space Grotesk', system-ui, sans-serif;
  --ease-tih15: cubic-bezier(0.34, 1.56, 0.64, 1);
  --animate-tih15-ripple: tih15-ripple 1.5s cubic-bezier(0, 0.2, 0.8, 1) infinite;
}
/* Keyframes have no utility form and never will - this is the category that
   belongs in CSS. The scale-based version replaces the original's width/height
   animation, so the rings expand on the compositor instead of relaying out. */

@keyframes tih15-ripple {
  0% {
    scale: 1;
    opacity: 0.6;
  }

  100% {
    scale: 1.4;
    opacity: 0;
  }
}
/* Root rule: the full-bleed contract, stated in CSS as well as in the markup's
   w-full min-h-svh, so the stage is correctly sized before the browser build compiles. */

.tih-15 {
  width: 100%;
  min-height: 100svh;
}

.tih-15 ::selection {
  background: oklch(0.8 0.13 185);
  color: #000;
}
```

How this works

The keyframe is a token. @theme turns a keyframe name into a utility:

@theme { --animate-tih15-ripple: tih15-ripple 1.5s cubic-bezier(0,0.2,0.8,1) infinite; }
@keyframes tih15-ripple {
  0%   { scale: 1;   opacity: 0.6 }
  100% { scale: 1.4; opacity: 0 }
}

The keyframe block itself stays in CSS — there is no utility syntax for keyframes and there should not be. What moves into the markup is when it runs.

Scale, not size. The original keyframe animates width, height, top and left, which relayouts every frame. Fixed-size rings centred with place-items-center and scaled from 1 to 1.4 produce the identical visual on the compositor.

Delays from an index. Three :nth-child delay rules become one utility reading --i, so a fourth ring is a copied <span>.

Make it yours

  • Ring count: copy a <span> and increment --i; the delay spacing is the 0.5s multiplier.
  • Reach: the 1.4 end scale in the keyframe.
  • Radar look: border-dashed on the rings.
  • Always-on (live status): swap group-hover:animate-tih15-ripple for the bare animate-tih15-ripple.
  • Per-card colour: the inline --ring property.

Gotchas — read before shipping

  • Keyframes cannot be utilities. The block stays in the stylesheet; only the animation's application is markup.
  • Keep the animation off at rest. A permanently running, invisible animation costs main-thread work even off-screen — group-hover: is what makes this cheap.
  • animate-none under motion-reduce: must beat the hover utility; the variant order in the class list is what makes that work.
  • Rings need explicit sizes. A scale on an auto-sized absolute element has nothing to scale from.
  • [animation-delay:calc(var(--i)*0.5s)] must be typed without spaces.
  • The browser CDN build compiles in the page and is for prototyping only. Ship the CLI or a plugin build.
