fancyBox is a JavaScript library used to present images, videos and any html content in an elegant way. It has all features you would expect - touch enabled, responsive and fully customizable.
jQuery 3+ is preferred, but fancyBox works with jQuery 1.9.1+ and jQuery 2+
If you experience issues with image zooming, then update jQuery to the latest (at least v3.2.1).
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:
You can install fancyBox by linking .css and .js 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>
You can download the latest version of fancyBox on GitHub.
Or just link directly to fancyBox files on cdnjs - https://cdnjs.com/libraries/fancybox.
fancyBox can also be installed via Bower or npm.
# NPM
npm install @fancyapps/fancybox --save
# Bower
bower install fancybox --save
The most basic way to use fancyBox is by adding the data-fancybox attribute to a link.
A caption can be added using the data-caption attribute. Example:
<a href="image.jpg" data-fancybox data-caption="My caption"> <img src="thumbnail.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.
Select elements with a jQuery selector and call the fancybox method:
<script type="text/javascript">
$("[data-fancybox]").fancybox({
// Options will go here
});
</script>
Using this method, click event handler is attached only to the currently selected elements.
To attach click event listener for elements that exist now or in the future, use selector option. Example:
$().fancybox({
selector : '[data-fancybox="images"]',
loop : true
});fancyBox can be activated at any point within Javascript and therefore does not necessarily need a trigger element. Example of displaying a simple message:
$.fancybox.open('<div class="message"><h2>Hello!</h2><p>You are awesome!</p></div>');See API section for more information and examples.
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:
<a href="image_1.jpg" data-fancybox="group" data-caption="Caption #1"> <img src="thumbnail_1.jpg" alt="" /> </a> <a href="image_2.jpg" data-fancybox="group" data-caption="Caption #2"> <img src="thumbnail_2.jpg" alt="" /> </a>
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:
<a href="images.php?id=123" data-type="image" data-caption="Caption"> Show image </a>
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 imagedata-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>fancyBox supports "scrset" so I 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.
$('[data-fancybox]').fancybox({
protect: true
});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.
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>
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
</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
}
})
Supported sites can be used with fancyBox by just providing the page URL:
<a data-fancybox href="https://www.youtube.com/watch?v=_sI_Ps7JSEk">

<a data-fancybox href="https://vimeo.com/191947042">

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:
<a data-fancybox data-options='{"caption" : "My caption", "src" : "https://codepen.io/about/", "type" : "iframe"}' href="javascript:;" class="btn">
Open external page
</a>
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 are methods which affect/handle instances:
// Close only the currently active or all fancyBox instances
$.fancybox.close( true );
// Open the fancyBox right away
$.fancybox.open( items, opts, index );
Gallery items can be collection of jQuery objects or array containing plain objects. 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;
});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'
}
},
{
src : '2_b.jpg',
opts : {
caption : 'Second caption'
}
}
], {
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>');In order to use these methods, you need an instance of the plugin's object.
var instance = $.fancybox.open(
// Your content and options
);Get reference to currently active instance:
var instance = $.fancybox.getInstance();The first argument of the callback is reference to 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);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;
}
}
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
},
thumbs : {
autoStart : false, // Display thumbnails on opening
hideOnClose : true, // Hide thumbnail grid when closing animation starts
parentEl : '.fancybox-container', // Container is injected into this element
axis : 'y' // Vertical (y) or horizontal (x) scrolling
}
Example (show thumbnails on start):
$('[data-fancybox="images"]').fancybox({
thumbs : {
autoStart : true
}
})
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;
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;
}
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();
}
});Example of creating reusable button:
// Create template for the 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'
]
});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
When you want to make your content selectable or clickable, you have two options:
touch:false
data-selectable="true" attribute to your html element
