# Harbour tide card with quay

## Where to use it
Tides decide when a boat can leave, and a curve alone is hard to feel. This card links the semidiurnal tide line to a small harbour scene: as you scrub the hour, the water rises along the depth marks on the stone quay and the moored boat rides up with it, rocking gently. It suits marinas, surf and fishing apps, coastal tourism and weather sites.
The main color is the sea and the curve, the second the hull and the time marker. Change the high tide time and range in the formula, or tap the four tide chips to jump straight to each one.

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 “Harbour tide card with quay” block (Cards) from AIMRAN Library to my project.
## What it is
The day's tide curve: drag the time and the water climbs or drops along the quay gauge with the boat floating on top.
## Chosen settings
- Main color: #0e7490
- Secondary color: #e85d3a
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Mareas en Cudillero"
## 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.
