Installation

You can use one of the following methods:

Yarn

yarn add baguettebox.js

Bower

bower install baguettebox.js --save

CDN

1. Use one of the following CDN providers:

• https://cdnjs.com/libraries/baguettebox.js
• https://jsdelivr.com/projects/baguettebox.js

3. Copy URLs of the latest version (both .js and .css files)

4. Paste the URLs in your HTML file:

<link rel="stylesheet" href="<CSS URL>">
<script src="<JS URL>" async></script>

Manually

1. Download baguetteBox.min.css and baguetteBox.min.js files from the dist folder.
2. Include them somewhere in your document:

<link rel="stylesheet" href="css/baguetteBox.min.css">
<script src="js/baguetteBox.min.js" async></script>

Importing

Traditional approach

If you don't use JavaScript modules and include the file with a <script> tag, you don't have to import anything explicitly. baguetteBox will be available in the global scope.

CommonJS

const baguetteBox = require('baguettebox.js');

ES2015 modules

import baguetteBox from 'baguettebox.js';

Sass

@import 'baguettebox.js/dist/baguetteBox.min.css';

Usage

Initialize the script by running:

baguetteBox.run('.gallery');

where the first argument is a selector to a gallery (or galleries) containing a tags. The HTML code may look like this:

<div class="gallery">
    <a href="img/2-1.jpg" data-caption="Image caption">
        <img src="img/thumbnails/2-1.jpg" alt="First image">
    </a>
    <a href="img/2-2.jpg">
        <img src="img/thumbnails/2-2.jpg" alt="Second image">
    </a>
    ...
</div>

To use captions put a title or data-caption attribute on the a tag.

Note: if you import baguetteBox using the <script> tag, remember to run it after the document has loaded:

<script>
window.addEventListener('load', function() {
  baguetteBox.run('.gallery');
});
</script>

Customization

You can pass an object with custom options as the second parameter.

baguetteBox.run('.gallery', {
    // Custom options
});

The following options are available:

| Option | Type | Default | Description | | --- | --- | --- | --- | | captions | Boolean | function(element) | true | Display image captions. Passing a function will use a string returned by this callback. The only argument is a element containing the image. Invoked in the context of the current gallery array | | buttons | Boolean | 'auto' | 'auto' | Display buttons. 'auto' hides buttons on touch-enabled devices or when only one image is available | | fullScreen | Boolean | false | Enable full screen mode | | noScrollbars | Boolean | false | Hide scrollbars when gallery is displayed | | bodyClass | String | 'baguetteBox-open' | Class name that will be appended to the body when lightbox is visible (works in IE 10+) | | ignoreClass | String | null | It will ignore images with given class put on a tag | | titleTag | Boolean | false | Use caption value also in the gallery img.title attribute | | async | Boolean | false | Load files asynchronously | | preload | Number | 2 | How many files should be preloaded | | animation | 'slideIn' | 'fadeIn' | false | 'slideIn' | Animation type | | afterShow | function | null | Callback to be run after showing the overlay | | afterHide | function | null | Callback to be run after hiding the overlay | | onChange | function(currentIndex, imagesCount) | null | Callback to be run when image changes | | overlayBackgroundColor | String | 'rgba(0,0,0,0.8)' | Background color for the lightbox overlay | | filter | RegExp | /.+\.(gif\|jpe?g\|png\|webp)/i | Pattern to match image files. Applied to the a.href attribute |

API

run(selector, userOptions)

Initialize baguetteBox.js

• @param selector {string} - valid CSS selector used by querySelectorAll
• @param userOptions {object} - custom options (see #Customization)
• @return {array} - an array of gallery objects (reflects elements found by the selector)

show(index, gallery)

Show (if hidden) and move the gallery to a specific index

• @param index {number} - the position of the image
• @param gallery {array} - gallery which should be opened, if omitted assumes the currently opened one
• @return {boolean} - true on success or false if the index is invalid

Usage:

const gallery = baguetteBox.run('.gallery');
baguetteBox.show(index, gallery[0]);

showNext

Switch to the next image

• @return {boolean} - true on success or false if there are no more images to be loaded

showPrevious

Switch to the previous image

• @return {boolean} - true on success or false if there are no more images to be loaded

hide

Hide the gallery

destroy

Remove the plugin with any event bindings

Responsive images

To use this feature, simply put data-at-{width} attributes on a tags with a value being the path to the desired image. {width} should be the maximum screen width the image can be displayed at. The script chooses the first image with {width} greater than or equal to the current screen width for best user experience. That last data-at-X image is also used in the case of a screen larger than X.

Here's an example of what the HTML code can look like:

<a href="img/2-1.jpg"
  data-at-450="img/thumbs/2-1.jpg"
  data-at-800="img/small/2-1.jpg"
  data-at-1366="img/medium/2-1.jpg"
  data-at-1920="img/big/2-1.jpg">
    <img src="img/thumbs/2-1.jpg">
</a>

If you have 1366x768 resolution baguetteBox.js will choose "img/medium/2-1.jpg". If, however, it's 1440x900 it'll choose "img/big/2-1.jpg". Keep the href attribute as a fallback (link to a bigger image e.g. of HD size) for older browsers.
