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.css"> </head> <body> <!-- Your HTML content goes here --> <!-- JS --> <script src="//code.jquery.com/jquery-3.1.1.min.js"></script> <script src="jquery.fancybox.min.js"></script> </body> </html>
Tips:
There are a few ways you can use fancyBox.
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 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>
Tip:
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>
To bind fancyBox events on any element, select with a jQuery selector and call the fancybox method:
<script type="text/javascript">
$("[data-fancybox]").fancybox({
// Options will go here
});
</script>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.
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({
image : {
protect: true
}
});For your Inline HTML you have to place a DIV Container into the content of the page:
<div style="display: none;" id="hidden-content">
<h2>Hello</h2>
<p>You are awesome.</p>
</div>
And then simply create a link using data-src attribute that matches CSS id selector of the element you want to open (#hidden-content in this example):
<a data-fancybox data-src="#hidden-content" href="javascript:;">
Hidden div
</a>
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-selector 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-selector="#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-src="http://codepen.io/fancyapps/full/jyEGGG/" href="javascript:;">
Webpage
</a>
<a data-fancybox data-src="http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf" 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 an "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.
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">

Set instance options by passing a valid object to fancybox() method:
$("[data-fancybox]").fancybox({
image : {
protect : true
}
});
Plugin options / defaults are exposed in $.fancybox.defaults namespace so you can easily adjust them globally:
$.fancybox.defaults.speed = 600;
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 : "iframe.html"}' href="javascript:;">
Open external page using iframe
</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( all );
// Open the fancyBox right away
$.fancybox.open( items, opts, index );
When calling fancyBox manually, each group 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:
$.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 : {
onComplete : function() {
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.getInstance();Or you can can just use fancyBox constructor:
var $instance = $("[data-fancybox]").fancybox();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 the other gallery item; accepts integer argument (an index of the desired 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 );
// Move slider to current position
// Update all slides (and their content) if needed
$instance.update( andSlides, andContent, duration );
// Update slide position and make content fit in slide if needed
$instance.updateSlide( slide, andContent );
// Update infobar values, navigation button states and reveal caption
$instance.updateControls( force );
// Load custom content into the slide
$instance.setContent( slide, content );
// 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
beforeMove : Before slide change transition starts
afterMove : After slide change transition is complete
onComplete : When slide change is complete and content has been loaded
onInit : When instance has been initialized
beforeClose : Before instance is closed
afterClose : After instance has been closed
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">
$("[data-fancybox]").fancybox({
onComplete: function( instance, slide ) {
// Tip: Each event passes useful information within the event object:
// Object containing references to interface elements
// (background, buttons, caption, etc)
// console.info( instance.$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>
It is also possible to attach an event handler for all instances.
To prevent interfering with other scripts, these events have been namespaced to .fb.
Here is an example of binding to the onComplete event:
$(document).on('onComplete.fb', function( e, instance, slide ) {
// Your code goes here
});
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:
slideShow : {
speed : 3000 // Slideshow speed in ms
},
touch : {
vertical : true // Allow vertical swipe
},
thumbs : {
showOnStart : false, // Display thumbnails on opening
hideOnClosing : true // Hide thumbnail grid when closing animation starts
}Example (show thumbnails on start):
$('[data-fancybox="images"]').fancybox({
thumbs : {
showOnStart : true
}
})
If you would inspect fancyBox instance object, you would find keys that names 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.close();
Thumbs.update();
Thumbs.hide();
Thumbs.show();
Thumbs.toggle();
FullScreen.isAvailable();
FullScreen.isActivated();
FullScreen.launch();
FullScreen.exit();
FullScreen.toggle();
SlideShow.start();
SlideShow.stop();
SlideShow.toggle();
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]' ).fancybox({
caption : function( instance, item ) {
var caption, link;
if ( item.type === 'image' ) {
caption = $(this).data('caption');
link = '<a href="' + item.src + '">Download image</a>';
return (caption ? caption + '<br />' : '') + link;
}
}
});
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 using callback to access toolbar element and append custom button:
$( '[data-fancybox]' ).fancybox({
onInit : function( instance ) {
instance.$refs.downloadButton = $('<a class="fancybox-button fancybox-download"></a>')
.appendTo( instance.$refs.buttons );
},
beforeMove: function( instance, current ) {
instance.$refs.downloadButton.attr('href', current.src);
}
});
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
