Usage

Standalone Plugin

When using the standalone variant (simple-lightbox(.min).js)

new SimpleLightbox('.some-element a', { /* options */ });

The jQuery-compatible (simple-lightbox.jquery(.min).js) variant works as before (v1.x):

$('.some-element a').simpleLightbox({ /* options */ });

With Webpack/Browserify/Parcel etc...

Choose the module file you want to import or require.

Module with Babel tranformation

import SimpleLightbox from "simplelightbox";

Plain ES Module without Babel

import SimpleLightbox from "simplelightbox/dist/simple-lightbox.esm"

Markup

For the default setup, you just need links that are pointing to images.

<div class="gallery">
    <a href="images/image1.jpg"><img src="images/thumbs/thumb1.jpg" alt="" title=""/></a>
    <a href="images/image2.jpg"><img src="images/thumbs/thumb2.jpg" alt="" title="Beautiful Image"/></a>
</div>

The markup inside the A-Tags can be whatever you want. In this example thumbnails of the big images. The 'title' tag is used by default to show a caption. For a complete example just look at the demo folder.
