About

A responsive two-column masonry gallery with modal dialog lightbox, keyboard navigation, and smooth focal frame previews. It is useful in design portfolios, photography journals, and editorial websites to present photo collections.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Masonry lightbox to your project and fits it to your theme.

Code

How Masonry lightbox is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

"use client";

import * as React from "react";
import Component, { type Props, type State } from "@/components/ui/masonry-lightbox";

const settings = { title: "An eye for the in-between." };
export const loopDuration = 6;

// Pure timeline: export frame n by passing n / 60. No timers or network calls.
export function showcase(time: number): State {
  const t = ((time % loopDuration) + loopDuration) % loopDuration;
  return { active: t < 2.4 ? 0 : t < 3.6 ? 1 : 2, open: t >= 1.2 && t < 4.8 };
}

export default function Demo(props: any = {}) {
  const { showcaseTime, ...incoming } = props;
  const merged = { ...settings, ...incoming };
  return (
    <div className="w-full min-h-[460px] flex items-center justify-center p-4 sm:p-6 bg-background">
      <Component
        {...merged}
        state={showcaseTime === undefined ? incoming.state : showcase(showcaseTime)}
        seeking={showcaseTime !== undefined || incoming.seeking}
      />
    </div>
  );
