## Where to use it

Marbling feels handmade and a bit luxurious. It works for the homepage of a ceramics studio, the packaging reveal of a cosmetics brand or the cover of an interior design portfolio. The veins drift sideways non-stop, so the pattern slowly reshapes itself. An animated marble background in HTML and CSS, shaped by an SVG filter.

Three close colors plus the dark background give the classic look; add a gold or cream tone for something closer to real stone. Keep text on a solid block or card, because the veins run through everything.

## Code

### HTML

```html
<div class="pt-marble"><svg width="0" height="0" style="position:absolute"><filter id="pt-marble-f" x="-20%" y="-20%" width="140%" height="140%"><feTurbulence type="fractalNoise" baseFrequency="0.004 0.007" numOctaves="4" seed="7"/><feDisplacementMap in="SourceGraphic" scale="200"/></filter></svg><i></i></div>
```

### CSS

```css
.pt-marble {
  --c1: #0071e3;
  --c2: #c4b5fd;

  /* densidad / escala */
  --o: 1;
  /* opacidad */
  --bg: #05060a;
  --fg: #ffffff;
  --blend: screen;
  min-height: 100vh;
}

.pt-marble {

I want to add the “Liquid marble” block (Backgrounds) from AIMRAN Library to my project.

## What it is
Veins of color flow across the screen like liquid marble or marbled paper, drawn with an SVG filter.

## Chosen settings
- Color 1: #0071e3
- Color 2: #c4b5fd
- 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-marble {
  position: relative;
  width: 100%;
  height: 100%;
  overflow: hidden;
  background-color: var(--bg);
  container-type: size;
  isolation: isolate;
}

.pt-marble>* {
  opacity: var(--o);
}

.pt-marble i {
  position: absolute;
  inset: -15%;
  --p: calc(110px * var(--d));
  filter: url(#pt-marble-f);
  background: repeating-linear-gradient(115deg,var(--bg) 0,var(--bg) calc(var(--p) * .36),var(--c1) calc(var(--p) * .5),var(--c2) calc(var(--p) * .56),var(--bg) calc(var(--p) * .72),var(--c3) calc(var(--p) * .8),var(--bg) var(--p));
  animation: pt-marble-s calc(30s / var(--k)) linear infinite;
}

@keyframes pt-marble-s {
  to {
    background-position: calc(var(--p) / 0.9063) 0;
  }
}

`;

export default function PatternMarble() {
  const ref = useRef(null);
  return (
    <>
      <style>{css}</style>
      <div
        ref={ref}
        className="pt-marble"
        style={{
          "--c1": "#0071e3",
          "--c2": "#c4b5fd",
          "--c3": "#14b8a6",
          "--k": 1,
          "--d": 1,
          "--o": 1,
          "--bg": "#05060a",
          "--fg": "#ffffff",
          "--blend": "screen",
          minHeight: "100vh",
        }}
      >
        <svg width="0" height="0" style={{ position: "absolute" }}><filter id="pt-marble-f" x="-20%" y="-20%" width="140%" height="140%"><feTurbulence type="fractalNoise" baseFrequency="0.004 0.007" numOctaves="4" seed="7" /><feDisplacementMap in="SourceGraphic" scale="200" /></filter></svg><i></i>
      </div>
    </>
  );
