Introduction
Get started with fancybox, probably the world’s most popular lightbox script.
Dependencies
jQuery 3+ is preferred, but fancybox works with jQuery 1.9.1+ and jQuery 2+
Compatibility
fancybox includes support for touch gestures and even supports pinch gestures for zooming. It is perfectly suited for both mobile and desktop browsers.
fancybox has been tested in following browsers/devices:
- Chrome
- Firefox
- IE10/11
- Edge
- iOS Safari
- Nexus 7 Chrome
Setup
You can install fancybox by linking
.css and
.js files to your html file. Make sure you also load the jQuery library. Below is a basic HTML template
to use as an example:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>My page</title> <!-- CSS --> <link rel="stylesheet" type="text/css" href="jquery.fancybox.min.css"> </head> <body> <!-- Your HTML content goes here --> <!-- JS --> <script src="//code.jquery.com/jquery-3.2.1.min.js"></script> <script src="jquery.fancybox.min.js"></script> </body> </html>
Download fancybox
Download the latest version of fancybox on
GitHub.
Or just link directly to fancybox files on cdnjs -
https://cdnjs.com/libraries/fancybox.
Package Managers
fancybox is also available on npm and Bower.
# NPM
npm install @fancyapps/fancybox --save
# Bower
bower install fancybox --save
Important
- Make sure you add the jQuery library before the fancybox JS file
- If you already have jQuery on your page, you shouldn't include it second time
- Do not include both fancybox.js and fancybox.min.js files
- Some functionality (ajax, iframes, etc) will not work when you're opening local file directly on your browser, the code must be running on a web server
How to Use
Initialize with data attributes
The most basic way to use fancybox is by adding the
data-fancybox attribute to your element. This will automatically bind click event that will start fancybox. Use
href or
data-src attribute to specify source of your content. Example:
<a href="image.jpg" data-fancybox data-caption="Caption for single image"> <img src="thumbnail.jpg" alt="" /> </a>
If you have a group of items, you can use the same attribute
data-fancybox value for each of them to create a gallery. Each group should have a unique value. Example:
<a href="image_1.jpg" data-fancybox="gallery" data-caption="Caption #1"> <img src="thumbnail_1.jpg" alt="" /> </a> <a href="image_2.jpg" data-fancybox="gallery" data-caption="Caption #2"> <img src="thumbnail_2.jpg" alt="" /> </a>
If you choose this method, default settings will be applied. See
options section for examples how to customize by changing defaults or using
data-options attribute.
Sometimes you have multiple links pointing to the same source and that creates duplicates in the gallery. To avoid that,
simply use
data-trigger attribute with the same value used for
data-fancybox attribute for your other links. Optionally, use
data-index attribute to specify index of starting element:
<a data-trigger="gallery" href="javascript:;">
<img src="thumbnail_1.jpg" alt="" />
</a>
Initialize with JavaScript
Select your elements with a jQuery selector (you can use any valid selector) and call the
fancybox method:
$('[data-fancybox="gallery"]').fancybox({
// Options will go here
});
Sometimes you might need to bind fancybox to dynamically added elements. Use
selector option to attach click event listener for elements that exist now or in the future. Example:
$().fancybox({
selector : '[data-fancybox="gallery"]',
loop : true
});
Info
Keep in mind, that selected items are not automatically grouped in the gallery. You can create one or more groups by using
the same value for
data-fancybox attribute, similarly to example from the previous section.
Use with Javascript
You can also open and close fancybox programmatically. Here are a couple of examples, visit API section for more information and demos.
Display simple message:
$.fancybox.open('<div class="message"><h2>Hello!</h2><p>You are awesome!</p></div>');Display iframed page:
$s.fancybox.open({
src : 'link-to-your-page.html',
type : 'iframe',
opts : {
afterShow : function( instance, current ) {
console.info( 'done!' );
}
}
});Important
fancybox attempts to automatically detect the type of content based on the given url. If it cannot be detected, the type
can also be set manually using
data-type attribute (or
type option). Example:
<a href="images.php?id=123" data-type="image" data-caption="Caption"> Show image </a>
Media types
Images
The standard way of using fancybox is with a number of thumbnail images that link to larger images:
<a href="image.jpg" data-fancybox="images" data-caption="My caption">
<img src="thumbnail.jpg" alt="" />
</a>By default, fancybox fully preloads an image before displaying it. You can choose to display the image right away. It will render and show the full size image while the data is being received. To do so, some attributes are necessary:
-
data-width- the real width of the image -
data-height- the real height of the image
<a href="image.jpg" data-fancybox="images" data-width="2048" data-height="1365">
<img src="thumbnail.jpg" />
</a>
You can also use these
width and
height properties to control size of the image. This can be used to make images look sharper on retina
displays. Example:
$('[data-fancybox="images"]').fancybox({
afterLoad : function(instance, current) {
var pixelRatio = window.devicePixelRatio || 1;
if ( pixelRatio > 1.5 ) {
current.width = current.width / pixelRatio;
current.height = current.height / pixelRatio;
}
}
});fancybox supports "srcset" so it can display different images based on viewport width. You can use this to improve download times for mobile users and over time save bandwidth. Example:
<a href="medium.jpg" data-fancybox="images" data-srcset="large.jpg 1600w, medium.jpg 1200w, small.jpg 640w">
<img src="thumbnail.jpg" />
</a>It is also possible to protect images from downloading by right-click. While this does not protect from truly determined users, it should discourage the vast majority from ripping off your files. Optionally, put the watermark over image.
$('[data-fancybox]').fancybox({
protect: true
});Video
YouTube and Vimeo videos can be used with fancyBox by just providing the page URL. Link to MP4 video directly or use trigger
element to display hidden
<video> element.
Use
data-width and
data-height attributes to customize video dimensions and
data-ratio for the aspect ratio.
<a data-fancybox href="https://www.youtube.com/watch?v=_sI_Ps7JSEk">
YouTube video
</a>
<a data-fancybox href="https://vimeo.com/191947042">
Vimeo video
</a>
<a data-fancybox data-width="640" data-height="360" href="video.mp4">
Direct link to MP4 video
</a>
<a data-fancybox href="#myVideo">
HTML5 video element
</a>
<video width="640" height="320" controls id="myVideo" style="display:none;">
<source src="https://www.html5rocks.com/en/tutorials/video/basics/Chrome_ImF.mp4" type="video/mp4">
<source src="https://www.html5rocks.com/en/tutorials/video/basics/Chrome_ImF.webm" type="video/webm">
<source src="https://www.html5rocks.com/en/tutorials/video/basics/Chrome_ImF.ogv" type="video/ogg">
Your browser doesn't support HTML5 video tag.
</video>Controlling YouTube & Vimeo video via URL parameters:
<a data-fancybox href="https://www.youtube.com/watch?v=_sI_Ps7JSEk&autoplay=1&rel=0&controls=0&showinfo=0">
YouTube video - hide controls and info
</a>
<a data-fancybox href="https://vimeo.com/191947042?color=f00">
Vimeo video - custom color
</a>Via JavaScript:
$('[data-fancybox]').fancybox({
youtube : {
controls : 0,
showinfo : 0
},
vimeo : {
color : 'f00'
}
});Inline HTML
For inline content, create a hidden element with unique id:
<div style="display: none;" id="hidden-content">
<h2>Hello</h2>
<p>You are awesome.</p>
</div>
And then simply create a link having
data-src attribute that matches ID of the element you want to open (preceded by a hash mark (#); in this
example -
#hidden-content):
<a data-fancybox data-src="#hidden-content" href="javascript:;">
Trigger the fancybox
</a>
The script will append small close button (if you have not disabled by
smallBtn:false) and will not apply any styles except for centering. Therefore you can easily set custom dimensions
using CSS.
Ajax
To load content via AJAX, you need to add a
data-type="ajax" attribute to your link:
<a data-fancybox data-type="ajax" data-src="my_page.com/path/to/ajax/" href="javascript:;">
AJAX content
</a>
Additionally it is possible to define a selector with the
data-filter attribute to show only a part of the response. The selector can be any string, that is a valid jQuery
selector:
<a data-fancybox data-type="ajax" data-src="my_page.com/path/to/ajax/" data-filter="#two" href="javascript:;">
AJAX content
</a>
Iframe
If the content can be shown on a page, and placement in an iframe is not blocked by script or security configuration of that page, it can be presented in a fancybox:
<a data-fancybox data-type="iframe" data-src="http://codepen.io/fancyapps/full/jyEGGG/" href="javascript:;">
Webpage
</a>
<a data-fancybox data-type="iframe" data-src="https://mozilla.github.io/pdf.js/web/viewer.html" href="javascript:;">
Sample PDF file
</a>
To access and control fancybox in parent window from inside an iframe:
// Adjust iframe height according to the contents
parent.jQuery.fancybox.getInstance().update();
// Close current fancybox instance
parent.jQuery.fancybox.getInstance().close();Iframe dimensions can be controlled by CSS:
.fancybox-slide--iframe .fancybox-content {
width : 800px;
height : 600px;
max-width : 80%;
max-height : 80%;
margin: 0;
}These CSS rules can be overridden by JS, if needed:
$("[data-fancybox]").fancybox({
iframe : {
css : {
width : '600px'
}
}
});
If you have not disabled iframe preloading (using
preload option), then the script will atempt to calculate content dimensions and will adjust width/height
of iframe to fit with content in it. Keep in mind, that due to
same origin policy, there are some limitations.
This example will disable iframe preloading and will display small close button next to iframe instead of the toolbar:
$('[data-fancybox]').fancybox({
toolbar : false,
smallBtn : true,
iframe : {
preload : false
}
})

Set instance options by passing a valid object to
fancybox() method:
$("[data-fancybox]").fancybox({
thumbs : {
autoStart : true
}
});
Plugin options / defaults are exposed in
$.fancybox.defaults namespace so you can easily adjust them globally:
$.fancybox.defaults.animationEffect = "fade";
Custom options for each element individually can be set by adding a
data-options attribute to the element. This attribute should contain the properly formatted JSON object.
It is also possible to quickly set any option using
parameterized name of the selected option, for example,
animationEffect would be
data-animation-effect:
<a data-fancybox data-options='{"caption" : "My caption", "src" : "https://codepen.io/about/", "type" : "iframe"}' href="javascript:;" class="btn btn-primary">
Example #1
</a>
<a data-fancybox data-animation-effect="false" href="https://source.unsplash.com/0JYgd2QuMfw/1500x1000" class="btn btn-primary">
Example #2
</a>
API
The fancybox API offers a couple of methods to control fancybox. This gives you the ability to extend the plugin and to integrate it with other web application components.
Core methods
Core methods are methods which affect/handle instances:
// Start new fancybox instance
$.fancybox.open( items, opts, index );
// Get refrence to currently active fancybox instance
$.fancybox.getInstance();
// Close currently active fancybox instance (pass `true` to close all instances)
$.fancybox.close();
// Close all instances and unbind all events
$.fancybox.destroy();
Starting facybox
When creating group objects manually, each item should follow this pattern:
{
src : '' // Source of the content
type : '' // Content type: image|inline|ajax|iframe|html (optional)
opts : {} // Object containing item options (optional)
}
Example of opening image gallery programmatically:
$.fancybox.open([
{
src : '1_b.jpg',
opts : {
caption : 'First caption',
thumb : '1_s.jpg'
}
},
{
src : '2_b.jpg',
opts : {
caption : 'Second caption',
thumb : '2_s.jpg'
}
}
], {
loop : false
});It is also possible to pass only one object. Example of opening inline content:
$.fancybox.open({
src : '#hidden-content',
type : 'inline',
opts : {
afterShow : function( instance, current ) {
console.info( 'done!' );
}
}
});
If you wish to display some html content (for example, a message), then you can use a simpler syntax. It is advised to use a wrapper around your content.
$.fancybox.open('<div class="message"><h2>Hello!</h2><p>You are awesome!</p></div>');Group items can be collection of jQuery objects, too. This can be used, for example, to create custom click event:
var $links = $('.fancybox');
$links.on('click', function() {
$.fancybox.open( $links, {
// Custom options
}, $links.index( this ) );
return false;
});Instance methods
In order to use these methods, you need an instance of the plugin's object. There are 3 common ways to get the reference.
1) Using API method to get currently active instance:
var instance = $.fancybox.getInstance();2) While starting fancybox programmatically:
var instance = $.fancybox.open(
// Your content and options
);3) From within the callback - first argument is always a reference to current instance:
$("[data-fancybox]").fancybox({
afterShow : function( instance, current ) {
console.info( instance );
}
});Once you have a reference to fancybox instance the following methods are available:
// Go to next gallery item
instance.next( duration );
// Go to previous gallery item
instance.previous( duration );
// Switch to selected gallery item
instance.jumpTo( index, duration );
// Check if current image dimensions are smaller than actual
instance.isScaledDown();
// Scale image to the actual size of the image
instance.scaleToActual( x, y, duration );
// Check if image dimensions exceed parent element
instance.canPan();
// Scale image to fit inside parent element
instance.scaleToFit( duration );
// Update position and content of all slides
instance.update();
// Update slide position and scale content to fit
instance.updateSlide( slide );
// Update infobar values, navigation button states and reveal caption
instance.updateControls( force );
// Load custom content into the slide
instance.setContent( slide, content );
// Show loading icon inside the slide
instance.showLoading( slide );
// Remove loading icon from the slide
instance.hideLoading( slide );
// Try to find and focus on the first focusable element
instance.focus();
// Activates current instance, brings it to the front
instance.activate();
// Close instance
instance.close();
You can also do something like this:
$.fancybox.getInstance().jumpTo(1);or simply:
$.fancybox.getInstance('jumpTo', 1);Events
fancybox fires several events:
beforeLoad : Before the content of a slide is being loaded
afterLoad : When the content of a slide is done loading
beforeShow : Before open animation starts
afterShow : When content is done loading and animating
beforeClose : Before the instance attempts to close. Return false to cancel the close.
afterClose : After instance has been closed
onInit : When instance has been initialized
onActivate : When instance is brought to front
onDeactivate : When other instance has been activatedEvent callbacks can be set as function properties of the options object passed to fancybox initialization function:
<script type="text/javascript">
$("[data-fancybox]").fancybox({
afterShow: function( instance, slide ) {
// Tip: Each event passes useful information within the event object:
// Object containing references to interface elements
// (background, buttons, caption, etc)
// console.info( instance.$refs );
// Current slide options
// console.info( slide.opts );
// Clicked element
// console.info( slide.opts.$orig );
// Reference to DOM element of the slide
// console.info( slide.$slide );
}
});
</script>Each callback receives two parameters - current fancybox instance and current gallery object, if exists.
It is also possible to attach event handler for all instances. To prevent interfering with other scripts, these events have
been namespaced to
.fb. These handlers receive 3 parameters - event, current fancybox instance and current gallery object.
Here is an example of binding to the
afterShow event:
$(document).on('afterShow.fb', function( e, instance, slide ) {
// Your code goes here
});
If you wish to prevent closing of the modal (for example, after form submit), you can use
beforeClose callback. Simply return
false:
beforeClose : function( instance, current, e ) {
if ( $('#my-field').val() == '' ) {
return false;
}
}
Modules
fancybox code is split into several files (modules) that extend core functionality. You can build your own fancybox version
by excluding unnecessary modules, if needed. Each one has their own
js and/or
css files.
Some modules can be customized and controlled programmatically. List of all possible options:
fullScreen : {
autoStart : false,
},
touch : {
vertical : true, // Allow to drag content vertically
momentum : true // Continuous movement when panning
},
// Hash value when initializing manually,
// set `false` to disable hash change
hash : null,
// Customize or add new media types
// Example:
/*
media : {
youtube : {
params : {
autoplay : 0
}
}
}
*/
media : {},
slideShow : {
autoStart : false,
speed : 4000
},

Couple of examples. Show thumbnails on start:
$('[data-fancybox="images"]').fancybox({
thumbs : {
autoStart : true
}
});Customize share url if displaying hidden video element:
$('[data-fancybox="test-share-url"]').fancybox({
buttons : ['share', 'close'],
hash : false,
share : {
url : function( instance, item ) {
if (item.type === 'inline' && item.contentType === 'video') {
return item.$content.find('source:first').attr('src');
}
return item.src;
}
}
});
If you would inspect fancybox instance object, you would find that same keys ar captialized - these are references for each
module object. Also, you would notice that fancybox uses common naming convention to prefix jQuery
objects with
$.
This is how you, for example, can access thumbnail grid element:
$.fancybox.getInstance().Thumbs.$gridThis example shows how to call method that toggles thumbnails:
$.fancybox.getInstance().Thumbs.toggle();List of available methods:
Thumbs.focus()
Thumbs.update();
Thumbs.hide();
Thumbs.show();
Thumbs.toggle();
FullScreen.request( elem );
FullScreen.exit();
FullScreen.toggle( elem );
FullScreen.isFullscreen();
FullScreen.enabled();
SlideShow.start();
SlideShow.stop();
SlideShow.toggle();
If you wish to disable hash module, use this snippet (after including JS file):
$.fancybox.defaults.hash = false;FAQ
#1 Opening/closing causes fixed element to jump
Simply add
compensate-for-scrollbar CSS class to your fixed positioned elements. Example of using Bootstrap navbar component:
<nav class="navbar navbar-inverse navbar-fixed-top compensate-for-scrollbar">
<div class="container">
..
</div>
</nav>
The script measures width of the scrollbar and creates
compensate-for-scrollbar CSS class that uses this value for
margin-right property. Therefore, if your element has
width:100%, you should positon it using
left and
right properties instead. Example:
.navbar {
position: fixed;
top: 0;
left: 0;
right: 0;
}#2 How to customize caption
You can use
caption option that accepts a function and is called for each group element. Example of appending image
download link:
$( '[data-fancybox="images"]' ).fancybox({
caption : function( instance, item ) {
var caption = $(this).data('caption') || '';
if ( item.type === 'image' ) {
caption = (caption.length ? caption + '<br />' : '') + '<a href="' + item.src + '">Download image</a>' ;
}
return caption;
}
});Add current image index and image count (the total number of images in the gallery) right in the caption:
$( '[data-fancybox="images"]' ).fancybox({
infobar : false,
caption : function( instance, item ) {
var caption = $(this).data('caption') || '';
return ( caption.length ? caption + '<br />' : '' ) + 'Image <span data-fancybox-index></span> of <span data-fancybox-count></span>';
}
});
Inside
caption method,
this refers to the clicked element. Example of using different source for caption:
$( '[data-fancybox]' ).fancybox({
caption : function( instance, item ) {
return $(this).find('figcaption').html();
}
});#3 How to create custom button in the toolbar
Example of creating reusable button:
// Create template for the button
$.fancybox.defaults.btnTpl.fb = '<button data-fancybox-fb class="fancybox-button fancybox-button--fb" title="Facebook">' +
'<svg viewBox="0 0 24 24">' +
'<path d="M22.676 0H1.324C.594 0 0 .593 0 1.324v21.352C0 23.408.593 24 1.324 24h11.494v-9.294h-3.13v-3.62h3.13V8.41c0-3.1 1.894-4.785 4.66-4.785 1.324 0 2.463.097 2.795.14v3.24h-1.92c-1.5 0-1.793.722-1.793 1.772v2.31h3.584l-.465 3.63h-3.12V24h6.115c.733 0 1.325-.592 1.325-1.324V1.324C24 .594 23.408 0 22.676 0"/>' +
'</svg>' +
'</button>';
// Make button clickable using event delegation
$('body').on('click', '[data-fancybox-fb]', function() {
window.open("https://www.facebook.com/sharer/sharer.php?u="+encodeURIComponent(window.location.href)+"&t="+encodeURIComponent(document.title), '','left=0,top=0,width=600,height=300,menubar=no,toolbar=no,resizable=yes,scrollbars=yes');
});
// Customize buttons
$( '[data-fancybox="images"]' ).fancybox({
buttons : [
'fb',
'close'
]
});#4 How to reposition thumbnail grid
There is currenty no JS option to change thumbnail grid position. But fancybox is designed so that you can use CSS to change position or dimension for each block (e.g., content area, caption or thumbnail grid). This gives you freedom to completely change the look and feel of the modal window, if needed. View demo on CodePen
#5 How to disable touch gestures/swiping
When you want to make your content selectable or clickable, you have two options:
-
