# Tower crane menu

> A site crane runs its trolley to the section you choose, lowers the hook and lifts it up, where it keeps swaying.

## Where to use it

A menu for a construction site: a yellow lattice tower crane stands over a row of concrete blocks, each one a section. When you choose one, the trolley runs along the jib, the cable drops, the hook catches the block and lifts it while the previous one goes back down, and the raised block keeps swaying gently. It suits builders, architects, engineering firms and property developers.

The main color paints the crane and the secondary color the concrete. Four blocks fit the jib best; the speed slider changes how fast the crane works, and reduced motion skips the trip and the swing.

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Tower crane menu” block (Navigation) from AIMRAN Library to my project.

## What it is
A site crane runs its trolley to the section you choose, lowers the hook and lifts it up, where it keeps swaying.

## Chosen settings
- Main color: #f5b301
- Secondary color: #a8a29e
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Obra"

## 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.
