yarn add simplelightbox

// Bower
bower install simplelightbox

// NPM
npm install simplelightbox

After that include simple-lightbox(.min).css and simple-lightbox(.min).js to your page.


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"


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>

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.

Multiple Lightboxes on one page

You can have multiple lightboxes on one page if you give them different selectors. Here is a small example:

var lightbox1 = $('.lighbox-1 a').simpleLightbox();
var lightbox2 = $('.lighbox-2 a').simpleLightbox();


You can customize Simplelightbox by changing the style in simplelightbox.css.

If you are using SASS, you can customize Simplelightbox with the following variables

$sl-font-family: Arial, Baskerville, monospace;
$sl-overlay-background: #fff;
$sl-navigation-color: #000;
$sl-caption-color: #fff;
$sl-caption-background: #000;

$sl-counter-fontsize: 1rem;
$sl-caption-fontsize: 1rem;
$sl-close-fontsize: 3rem;

$sl-breakpoint-medium: 35.5em; // 568px, when 1rem == 16px
$sl-breakpoint-large:  50em;   // 800px, when 1rem == 16px

$sl-arrow-fontsize-small:  2rem;
$sl-arrow-fontsize-medium: 3rem;
$sl-arrow-fontsize-large:  3rem;
$sl-img-border-small:  0 none;
$sl-img-border-medium: 0 none;
$sl-img-border-large:  0 none;
$sl-iframe-border-small:  0 none;
$sl-iframe-border-medium: 0 none;
$sl-iframe-border-large:  0 none;

$add-vendor-prefixes: true !default;


using gulp
Run gulp watch to enable continous watching of both src/simple-lightbox.js and src/simple-lightbox.scss. Both files will be compiled to dist/simple-lightbox.js and dist/simple-lightbox.css respectively. Open dist/index.html in your browser to inspect your changes...

Just call gulp build to have all files and variants created inside dist!
