Custom shell lightbox: A gallery grid that opens a borderless full-bleed lightbox, showing how one open, close and focus engine can wear a completely custom shell.

## Frameworks

react, vue, svelte, astro, html

## Preview controls

These controls are passed to the demo. Defaults and limits describe the preview; consult the implementation for its full prop API.

| Name | Type | Default | Options or constraints |
| --- | --- | --- | --- |
| imageCount | number | 5 | From 3 to 10; step 1 |
| backdropOpacity | number | 92 | From 60 to 100; step 2 |
| showCaption | boolean | true | No additional limit in the metadata. |

## Usage notes

Custom shell lightbox uses the wide preview frame with a dark theme setting.

### Which frameworks are available for Custom shell lightbox?

Custom shell lightbox is available for React, Vue, Svelte, Astro, HTML. The live preview uses React; the source observations below apply to index.tsx. Check the selected port before relying on the same interactions.

### What does Custom shell lightbox depend on?

The React metadata lists these npm dependencies beyond React: motion.

### What accessibility details are visible in Custom shell lightbox?

The React source for Custom shell lightbox includes: native elements (button); attributes and handlers (aria-hidden, aria-label, aria-modal, onKeyDown, tabIndex); explicit roles (dialog); key comparisons (ArrowLeft, ArrowRight, Escape). These are source observations. Verify accessible names, focus order and keyboard behavior in the composed page.

### How does Custom shell lightbox handle reduced motion?

Custom shell lightbox reads the motion preference in its React source through useReducedMotion(). Preference-dependent expressions in index.tsx: duration: reduceMotion ? 0.001 : 0.28; scale: reduceMotion ? 1 : 0.97. Check the full implementation, shared styles and selected port with reduced motion enabled; these observations do not establish that every animation stops.
