Options

Fancybox has many options that allow for easy customization. Several options accept a method and use a return value. This allows, for example, to set options like wheel depending on whether the user is using a touchpad mouse device.

Declarative Usage

Use the Fancybox.bind() method to launch Fancybox with custom options when the user clicks on the matching element.

js
Fancybox.bind("[data-fancybox]", {
  hideScrollbar: false,
});

If you're having trouble setting the options, make sure the selector actually returns your elements, e.g. check the return value of document.querySelectorAll(your_selector):

js
document.querySelectorAll("[data-fancybox]");

Programmatic Usage

You can pass a set of options as a second parameter into a Fancybox constructor.

js
new Fancybox(
  // Array containing gallery items
  [
    // Gallery item
    {
      src: "image-a.jpeg",
      thumb: "thumbnail-a.jpeg",
    },
  ],
  // Gallery options
  {
    hideScrollbar: false,
  }
);

Global Options

You might want to set options that are common to all instances. Use Fancybox.defaults static property to change default options:

js
Fancybox.defaults.showClass = "f-scaleIn";

If you want to change several values at the same time:

js
Fancybox.defaults = {
  ...Fancybox.defaults,
  showClass: "f-scaleIn",
  hideClass: "f-scaleOut",
};

Component Hierarchy

Fancybox is built around the Carousel component, you can customise it using Carousel option. This example disables infinite navigation:

js
Fancybox.bind("[data-fancybox]", {
  Carousel: {
    infinite: false,
  },
});

JSFiddle Example

This example shows how to change the animations:

js
Fancybox.bind("[data-fancybox]", {
  // Transition effect when changing gallery items
  Carousel: {
    transition: "slide",
  },
  // Disable image zoom animation on opening and closing
  Images: {
    zoom: false,
  },
  // Custom CSS transition on opening
  showClass: "f-fadeIn",
});

JSFiddle Example

Since Carousel component is built around the Panzoom component, you can use Panzoom option to, for example, speed up the swipe animation:

js
Fancybox.bind("[data-fancybox]", {
  Carousel: {
    Panzoom: {
      decelFriction: 0.5,
    },
  },
});
