Documentation

Install

To install SimpleLightbox you can do the following:

// YARN
yarn add simplelightbox

//Bower
bower install simplelightbox

//NPM
npm install simplelightbox
				

Simple include simplelight-box.css and simple-lightbox.js to your page and use:

Usage

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

var lightbox = new SimpleLightbox('.gallery a', { /* options */ });

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

var lightbox = $('.gallery a').simpleLightbox({ /* options */ });

SimpleLightbox supports ES-Modules. So you can import and use it like:

import SimpleLightbox from "simplelightbox/dist/simple-lightbox.modules.js";

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 by default used to show a caption. For a whole example just look at the demo folder.
