## Where to use it
A dot grid wave feels technical but friendly, so it fits the hero of a developer tool, the landing page of an analytics product or a “coming soon” page before a hardware launch. The ripple always starts in the middle and pulls the eye to whatever sits there. It’s an animated dot pattern background built with CSS only.
Put your logo or headline right in the center and let the wave do the framing. If the dots feel too busy on a large monitor, lower the density or the opacity before you start changing colors.

I want to add the “Dot grid wave” block (Backgrounds) from AIMRAN Library to my project.
## What it is
A grid of dots where each one lights up as a ripple travels outward from the center.
## Chosen settings
- Color 1: #0071e3
- Color 2: #8b5cf6
- Color 3: #14b8a6
- Speed: 1x (from 0.2 to 3x)
- Density / scale: 1x (from 0.5 to 2x)
- Opacity: 1 (from 0.2 to 1)
## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
## Reference code
```tsx
// @ts-nocheck
import { useEffect, useRef } from "react";
const css = `
.pt-dots {
position: relative;
width: 100%;
height: 100%;
overflow: hidden;
background-color: var(--bg);
container-type: size;
isolation: isolate;
}
.pt-dots>* {
opacity: var(--o);
}
.pt-dots {
display: grid;
grid-template-columns: repeat(22,1fr);
grid-template-rows: repeat(14,1fr);
place-items: center;
padding: 2%;
}
.pt-dots i {
width: calc(6px * var(--d));
aspect-ratio: 1;
border-radius: 50%;
background: var(--c1);
animation: pt-dots-w calc(3.2s / var(--k)) ease-in-out infinite backwards;
animation-delay: calc(var(--r) * .12s / var(--k));
}
@keyframes pt-dots-w {
0%,100% {
transform: scale(.6);
opacity: calc(var(--o) * .25);
}
18% {
transform: scale(1.8);
opacity: var(--o);
background: var(--c2);
box-shadow: 0 0 14px var(--c2);
}
40% {
transform: scale(1);
opacity: calc(var(--o) * .6);
background: var(--c3);
}
}
`;
export default function PatternDots() {
const ref = useRef(null);
return (
<>
);
}
```
