Features

Everything a lightbox needs. Nothing it doesn't.

Fullscreen Viewer

Click any image to open it fullscreen with a smooth fade transition. Keyboard navigation with Escape to close and arrow keys for galleries.

Smooth Zoom

Scroll to zoom on desktop with momentum. Pinch to zoom on touch devices with proper inertia. Double-tap to toggle zoom level. Pan with drag.

Zero Dependencies

Pure vanilla JavaScript. No jQuery, no React, no framework runtime. One JS file, one CSS file. Works everywhere JavaScript runs.

Touch & Desktop

First-class touch support with pinch, pan, and swipe gestures. Desktop users get scroll zoom, keyboard nav, and click-outside-to-close.

Usage

Two lines to get started

index.html

<link rel="stylesheet" href="nitrolitebox.css"> <script src="nitrolitebox.js"></script>  <img src="photo.jpg" data-litebox />  <img src="photo-1.jpg" data-litebox="gallery" /> <img src="photo-2.jpg" data-litebox="gallery" /> <img src="photo-3.jpg" data-litebox="gallery" />

Add data-litebox to any image. That's it.
