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
Android 7.0 Tablet
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:
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:
If you choose this method, default settings will be applied. See
options section for examples how to customize
by changing defaults, using
data-options attribute or by initializing with
JavaScript.
Info
Sometimes you have multiple links pointing to the same source and that creates duplicates in the gallery.
To avoid that, simply use
data-fancybox-trigger attribute with the same value used for
data-fancybox attribute for your other links. Optionally, use
data-fancybox-index attribute to specify index of starting element:
Info
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.
All selected items will be automatically grouped in the gallery. Example:
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
fancybox is designed to display images, video, iframes and any HTML content. For your convenience, there is
a built in support for inline content and ajax.
Images
The standard way of using fancybox is with a number of thumbnail images that link to larger images:
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:
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:
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:
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.
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>
If you need to display content from another page, add data-fancybox and data-type="iframe"
attributes to your link. This would create <iframe> element that allows to
embed an entire web document inside the modal.
If you have not disabled iframe preloading (using
preload option), 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:
How to access and control fancybox in parent window from inside an iframe:
// Close current fancybox instance
parent.jQuery.fancybox.getInstance().close();
// Adjust iframe height according to the contents
parent.jQuery.fancybox.getInstance().update();
Inline
fancybox can be used to display any HTML element on the page.
First, create a hidden element with unique ID:
<div style="display: none;" id="hidden-content">
<h2>Hello</h2>
<p>You are awesome.</p>
</div>
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.
Info If necessary, you can make your element (and similarly any other
html content) scrollable by adding additional wrapping element and some CSS -
view demo on CodePen.
Ajax
To load your content via AJAX, you need to add a
data-type="ajax" attribute to your link:
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:
Quick reference for all default options as defined in the source:
var defaults = {
// Close existing modals
// Set this to false if you do not need to stack multiple instances
closeExisting: false,
// Enable infinite gallery navigation
loop: false,
// Horizontal space between slides
gutter: 50,
// Enable keyboard navigation
keyboard: true,
// Should allow caption to overlap the content
preventCaptionOverlap: true,
// Should display navigation arrows at the screen edges
arrows: true,
// Should display counter at the top left corner
infobar: true,
// Should display close button (using `btnTpl.smallBtn` template) over the content
// Can be true, false, "auto"
// If "auto" - will be automatically enabled for "html", "inline" or "ajax" items
smallBtn: "auto",
// Should display toolbar (buttons at the top)
// Can be true, false, "auto"
// If "auto" - will be automatically hidden if "smallBtn" is enabled
toolbar: "auto",

Set instance options by passing a valid object to fancybox() method:
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
(remember, strings should be wrapped in double quotes).
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>
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 fancybox
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:
If you wish to quickly display some html content (for example, a message), then you can use a simpler
syntax. Do not forget to use a wrapping element around your content.
$.fancybox.open('<div class="message"><h2>Hello!</h2><p>You are awesome!</p></div>');
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 activated
Event 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:
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:
$.fancybox.getInstance().Thumbs.$grid
This example shows how to call method that toggles thumbnails:
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:
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
If you are combining fancybox with slider/carousel script and that script clones items to enable infinite
navigation, then duplicated items will appear in the gallery.
To avoid that -
1) initialise fancybox on all items except cloned;
2) add custom click event on cloned items and trigger click event on corresponding "real" item. Here is an
example using Slick slider:
',
btnTpl: {
download: '' +
'' +

zoom: '",
close: '",
