Chocolat is a responsive lightbox
What you are looking for is in the /dist/ folder.
Demo page is here
You can install chocolat as a node module
(css from node_modules has to be linked in your html file anyway)
yarn add chocolat
or
npm install chocolat
Or the old school way by linking dist/js/jquery.chocolat.js and dist/css/chocolat.css to your html file
<div id="example1" data-chocolat-title="Set title">
<a class="chocolat-image" href="img/a.jpg" title="image caption a">
A <!-- you can display a thumbnail here : <img src="thumb/a.jpg" /> -->
</a>
<a class="chocolat-image" href="img/b.jpg" title="image caption b">
B <!-- you can display a thumbnail here : <img src="thumb/b.jpg" /> -->
</a>
</div>$(document).ready(function(){
$('#example1').Chocolat();
