zoomwall.js is a content-focused photo gallery using a horizontal masonry layout that scales up in lightbox mode.

Visit ericleong.github.io/zoomwall.js for a demo.

For those using npm

$ npm install zoomwall.js

First, add a reference to zoomwall.css in your HTML file, like this:

<link rel="stylesheet" type="text/css" href="zoomwall.css" />

Add the zoomwall class to the container element.

To have the browser determine when to load a high resolution image, use responsive images.

<div id="gallery" class="zoomwall">
  <img
    srcset="01_lowres.jpg 200w, 01_highres.jpg 800w"
    sizes="(max-width: 1200px) 200px, 800px"
    src="01_lowres.jpg"
  />
  <img
    srcset="02_lowres.jpg 200w, 02_highres.jpg 800w"
    sizes="(max-width: 1200px) 200px, 800px"
    src="02_lowres.jpg"
  />
</div>

Include high resolution photos using the data-highres attribute of each <img> tag.

<div id="gallery" class="zoomwall">
  <img src="01_lowres.jpg" data-highres="01_highres.jpg" />
  <img src="02_lowres.jpg" data-highres="02_highres.jpg" />
</div>

See documentation. Remember to import the module.

import * as zoomwall from "zoomwall.js";

Run zoomwall.create() on the container element (#gallery in this example), after they have loaded.

window.onload = function () {
  zoomwall.create(document.getElementById("gallery"));
};

Enable support for paging through photos with the left and right arrow keys by setting the second argument to true, like this: zoomwall.create(<element>, true).
