# Fisheye Grid Gallery

> A photo grid that magnifies like a dock: the photo under the pointer, finger or keyboard focus grows to about twice its size while its rows and columns squeeze to make room, then opens full size from its own cell.

## Overview

At rest it is an ordinary, even photo grid: 48 photographs in eight columns and six rows, sized to fill whatever box you give it. Move the pointer over it and the grid behaves like a magnifying dock in two directions at once. The photo underneath swells to about twice its size, its neighbours give way smoothly in its row and its column, and the whole grid stays a perfect tiling: nothing overlaps, no gaps open, and the grid never grows past its box. Each photo is cropped to fill its cell, so as a cell grows you see more of the picture, and a caption fades in on the one you are looking at.

The swell follows a slow pointer closely and trails a fast one, catching up like a liquid lens, and the grid eases back to even when the pointer leaves. Click a photo and it lifts out of its cell and opens full size over the gallery, with the sharp file fading in over the thumbnail; previous and next walk the set, and Escape or Close flies it back into its own cell. Keyboard visitors get the same lens: arrow keys walk a focus cursor cell to cell, the swell follows it, and Enter opens. On a phone, drag a finger across the grid to use it as a loupe and tap to open.

## Features

- Two-way fisheye: the photo under the pointer grows while its whole row and column give way, in both directions at once
- The grid always tiles its box exactly: no overlap, no gaps, constant width and height, whatever the lens is doing
- Smooth, liquid tracking: close on slow movement, a slight trail on fast sweeps, and an eased return to an even grid
- Photos are cropped to fill their cells, so a growing cell reveals more of the picture; the caption appears only on the magnified one
- Click, tap or Enter opens the photo full size from its own cell, with the sharp file fading in over the thumbnail
- Viewer with previous and next, arrow keys, swipe on touch, a counter and caption, and Escape or Close flying the photo back into its cell
- Keyboard cursor with a single tab stop: arrow keys, Home and End walk the grid and the lens follows the focus
- Touch loupe: drag a finger across the grid and the swell follows it; in a longer page a quick vertical swipe still scrolls the page
- Lens strength, spread, follow speed and column count set from data attributes; columns adapt to the container (8, 6, then 4 on phones)
- Only small thumbnails load up front; full-size files load when the viewer opens, with the neighbours fetched ahead
- Reduced motion: an even grid with a quiet focus ring and a crossfading viewer; no JavaScript: a plain grid of links with captions
- Small API (open, close, next, prev, focus, relax, setMagnify, revert) and focus, open and close events; several galleries per page stay independent

## Use Cases

- Photography portfolios where visitors want to scan dozens of images and still see each one properly
- Travel, architecture and interiors galleries with a mix of landscape and portrait shots
- Product, lookbook and press image libraries that should read as a tidy grid until someone explores
- Event and agency archives that need a gallery to drop onto an existing page without restyling it

## Vibe-Code Ready Setup

This effect includes `START-HERE-AI.md`, a product-specific copy-paste setup prompt for Cursor, Claude Code, ChatGPT, GitHub Copilot, Windsurf, Gemini, and other coding assistants. It tells the assistant to inspect the existing stack, integrate the supplied files, preserve the design, scope selectors, retain accessibility and responsive behaviour, add framework-appropriate GSAP cleanup, and report what it tested.

## How It Works

The gallery is an ordinary list of links: each one points at the full-size photograph and wraps a small thumbnail and a short caption. Without JavaScript that list is the whole gallery, a grid of links with captions, and with JavaScript it stays the same accessible list while the script takes over its sizing.

The grid is a CSS grid whose column widths and row heights are recalculated many times a second from how far each row and column is from the point you are looking at. Because only the proportions change, the tracks always add up to the same box, which is why the grid can never gap or overlap. GSAP's ticker eases the lens towards the pointer, the finger or the keyboard cursor, and stops running once everything has settled. The viewer is a GSAP timeline that carries the photo from its cell to full size and back. Everything the script adds, from the viewer to the inline grid sizes and listeners, is removed again on revert().

## Documentation

How this effect works and how it goes into a page. The reference you use once you own the files (worked examples, events, the programmatic API, the class list) ships with the download.

### Quick Start

**1. Add to your HTML `<head>`:**

_In your download: the working code for this step, in `index.html`._

**2. Add before the closing `</body>` tag:**

_In your download: the working code for this step, in `index.html`._

**3. Add the gallery anywhere in your `<body>`:**

_In your download: the working code for this step, in `index.html`._

Give it a height (see below) and it is done. Each link points at the full-size file, which only loads when the viewer opens it.

### Using It With Your Own Design

**What the effect needs from your markup:** a `[data-fisheye-grid]` element containing a `.fisheye__grid` list of `.fisheye__cell` items, each holding one `a.fisheye__item` whose `href` is the full-size image and which wraps an `<img>` thumbnail. `data-width` and `data-height` on the link give the full image's shape, so the viewer can size the photo before the file arrives (without them it uses the thumbnail's shape). The caption is optional: the script reads `data-caption` on the link, then the `.fisheye__caption` text, then the image's `alt`. Any button inside the gallery with `data-fisheye-magnify="2.2"` (or another number) becomes a lens strength switch with an `aria-pressed` state; the demo's Soft / Medium / Strong row is just three of those.

**What is only the demo's styling:** the Hanken Grotesk font, the grey palette, the hint line, the lens control row and its pill styling, the caption chip, the viewer's round buttons and the full-window `.showcase-shell` layout. Delete or restyle any of it. The tokens at the top of `.fisheye` set the gutter (`--fisheye-gap`, 3px), corner radius (`--fisheye-radius`) and empty-cell colour (`--fisheye-cell`).

**CSS the effect depends on:**

- **A height.** The grid fills a fixed box and the script only redistributes it. Set `--fisheye-height` on `.fisheye` (default `min(80vh, 760px)`), or give the element a height in your layout and set `--fisheye-height: auto` as the demo does. The rows share that height evenly at rest.
- **The `.has-js .fisheye__grid` rules**: `display: grid`, `minmax(0, 1fr)` tracks, `overflow: hidden` and the `--fisheye-columns` container queries (8 columns, 6 below 900px, 4 below 600px of gallery width). Change the breakpoints or counts there, or set `data-columns`.
- **Cells that clip and photos that cover**: `.fisheye__cell` is `position: relative; overflow: hidden` and the image is `object-fit: cover` at 100% by 100%, so a growing cell reveals more of the photo rather than stretching it.
- **`touch-action: pan-y pinch-zoom`** on the grid, which lets the script decide when a finger drag is the loupe (see Touch below).
- The viewer is drawn inside the gallery element (`position: absolute; inset: 0`), so `.fisheye` must stay `position: relative`.

### Options

Set these as data attributes on the `[data-fisheye-grid]` element.

| Attribute | Values | Default | Description |
|-----------|--------|---------|-------------|
| `data-magnify` | `1` to `6` | `2.2` | How large the photo under the pointer grows, in rest cells. With very few columns or rows the size is capped so the others keep a usable sliver (on four columns it is about 2.5). |
| `data-radius` | `0.4` to `6` | `1.25` | How far the swell spreads, in cells. Smaller is a tighter lens; larger moves more of the grid. It is narrowed automatically when the grid has too few tracks to afford it. |
| `data-columns` | Any whole number | from CSS | Fixed column count, overriding `--fisheye-columns`. Rows follow from the number of photos. |
| `data-follow` | `1` to `30` | `11` | How quickly the swell catches up with the pointer. Lower trails further behind a fast sweep; higher sticks closer. |
| `data-touch` | `auto`, `hold`, `drag` | `auto` | When a finger drag becomes the loupe. `drag`: always, and the page never scrolls from the grid (best for a full-screen gallery). `hold`: after a short hold or a sideways drag, while a quick vertical swipe scrolls the page. `auto`: `drag` when nothing around the gallery can scroll, `hold` otherwise (including inside an iframe). |

### Accessibility

- **Keyboard:** the grid is one tab stop. Arrow keys walk a focus cursor cell to cell, Home and End jump to the ends of the row (with Ctrl, to the first and last photo), and the swell follows the cursor, so keyboard visitors see the same magnified photo and caption. Enter or Space opens the viewer.
- **Viewer:** a labelled modal dialog. Focus moves to Close, Tab cycles its three buttons, the rest of the gallery is made inert, arrow keys step through the set, and Escape, Close or a click outside the photo closes it and returns focus to the photo's link. A polite live region announces "20 / 48" and the caption on each step.
- **Screen readers:** the gallery stays an ordinary list of links named by each image's `alt` text; the visible caption is `aria-hidden` so it is not read twice.
- **Touch:** see `data-touch`. A tap opens the viewer; after a loupe drag the magnified photo holds for a moment and then the grid settles. In the viewer, swipe left or right to step.
- **Reduced motion:** no fisheye and no easing. The grid stays even, the focused photo gets a quiet two-tone ring and its caption, and the viewer opens, steps and closes with short crossfades. Changing the preference while the page is open rebuilds the gallery in the other mode.
- **No JavaScript:** the gallery is a plain responsive grid of linked thumbnails with their captions, and every photo links to its full-size file.

### Photographs

The demo ships 48 photographs as baked WebP derivatives in `assets/img/`: `gNN.webp` thumbnails (432 by 324, or 360 by 480 for portrait subjects, about 760 KB for all 48) that load up front, and `gNN-full.webp` files (1600px on the long edge, at the photo's own shape) that load only when the viewer opens a photo, together with its two neighbours. They are from Pexels and Unsplash and used under the [Pexels License](https://www.pexels.com/license/) and the [Unsplash License](https://unsplash.com/license). Replace them with your own photographs for production; the gallery works with any number.

To regenerate or change them, edit `assets/img-manifest.json` and run `bun scripts/build-template-assets.ts fisheye-grid-gallery` from a GSAP Vault checkout, or export your own thumbnails at a size that covers the magnified cell (about 450px wide at the default strength in a 1200px wide gallery).

### Dependencies

**Required:**
- GSAP 3.12+ (core only). One GSAP ticker eases the lens and stops once it has settled; GSAP timelines carry the photo into and out of the viewer; GSAP's context and media queries handle the reduced-motion rebuild and `revert()`. The demo is pinned to GSAP 3.15.0.

No plugins, no Lenis and no other libraries.

### Browser Support and Performance

All current browsers (CSS grid, container queries and the `inert` attribute). Each frame of the lens rewrites two grid-template values on one element, so the cost is one layout of the grid's cells; it stays smooth with 48 photos and comfortably beyond. Nothing runs while the grid is at rest. Keep thumbnails small (around 10 to 25 KB each), since all of them load up front, and keep full-size files for the viewer.
