# Submarine porthole

> A brass porthole with thick glass that bends the sea at the edges; go deeper and the jellyfish arrive.

## Where to use it

A riveted hull with a brass porthole and eight bolts, looking out onto the open sea. The view is slightly magnified and a ring of stronger blur at the rim imitates thick, curved glass, with curved reflections on top. Light rays, fish, drifting particles and glowing jellyfish all react to the depth you set.

Drag the depth slider from the surface to two hundred meters to darken the water, fade the sunbeams and bring out the bioluminescence. Recolor the shallow water and the brass for diving schools, aquariums or ocean education.

## 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 “Submarine porthole” block (Liquid Glass) from AIMRAN Library to my project.

## What it is
A brass porthole with thick glass that bends the sea at the edges; go deeper and the jellyfish arrive.

## Chosen settings
- Main color: #0ea5e9
- Secondary color: #c08a3e
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)

## 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.
