## Where to use it

This 3D push button feels like a real key, so it shines in playful interfaces: the “Check answer” button of a language app, the “Play” screen of a browser game or the “Next” step in a kids' learning site. Hovering lifts it a little and pressing pushes it flat against its own shadow.

The shadow is a darker shade of the main color, so medium tones work better than very dark ones. Rounded, friendly typefaces suit it. For a bank, a law firm or anything that should feel serious, choose a flatter button instead.

````text
I want to add the “3D push button” block (Buttons) from AIMRAN Library to my project.

## What it is
A chunky button with a solid shadow underneath that sinks all the way down when you press it.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Press"

## 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
import type { CSSProperties } from "react";

const css = `
.uv-3d {
  font-family: -apple-system,BlinkMacSystemFont,"SF Pro Text","Inter",system-ui,sans-serif;
  font-size: var(--s);
  font-weight: 600;
  line-height: 1;
  padding: 1em 2em;
  border: 0;
  border-radius: 999px;
  cursor: pointer;
  -webkit-tap-highlight-color: transparent;
  border-radius: .8em;
  color: #fff;
  background: var(--c1);
  box-shadow: 0 .4em 0 color-mix(in srgb,var(--c1) 60%,#000),0 .6em 1em -.2em rgba(0,0,0,.3);
  transition: transform .12s cubic-bezier(.25,.1,.25,1),box-shadow .12s cubic-bezier(.25,.1,.25,1);
}

.uv-3d:hover {
  transform: translateY(-.1em);
  box-shadow: 0 .5em 0 color-mix(in srgb,var(--c1) 60%,#000),0 .8em 1.2em -.2em rgba(0,0,0,.3);
}

.uv-3d:active {
  transform: translateY(.4em);
  box-shadow: 0 0 0 color-mix(in srgb,var(--c1) 60%,#000),0 .1em .3em rgba(0,0,0,.3);
}
`;

export default function Btn3d() {
  return (
    <>
      <style>{css}</style>
      <div
        style={{
          "--c1": "#0071e3",
          "--c2": "#8ec5ff",
          "--s": "16px",
          "--k": "1",
          "--fg": "#1d1d1f",
          "--bg": "#f5f5f7",
        } as CSSProperties}
      >
        <button className="uv-3d">Press</button>
      </div>
    </>
  );
}
```
