• Simple JS API

basicLightbox depends on the following browser features and APIs:

• Array.from
• Node​List​.prototype​.for​Each
• Object.assign
• window.requestAnimationFrame

Some of these APIs are capable of being polyfilled in older browsers. Check the linked resources above to determine if you must polyfill to achieve your desired level of browser support.

We recommend installing basicLightbox using npm or yarn.

npm install basiclightbox

yarn add basiclightbox

Include the CSS file in the head tag and the JS file at the end of your body tag…

<link rel="stylesheet" href="dist/basicLightbox.min.css">

<script src="dist/basicLightbox.min.js"></script>

…or skip the JS file and use basicLightbox as a module:

const basicLightbox = require('basiclightbox')

import * as basicLightbox from 'basiclightbox'

Creates a new basicLightbox instance.

Be sure to assign your instance to a variable. Using your instance, you can…

• …show and hide the lightbox.
• …check if the the lightbox is visible.
• …modify the content of the lightbox.

Examples:

const instance = basicLightbox.create(`
	<h1>Dynamic Content</h1>
	<p>You can set the content of the lightbox with JS.</p>
`)

const instance = basicLightbox.create(`
	<h1>Not closable</h1>
	<p>It's not possible to close this lightbox with a click.</p>
`, {
	closable: false
})

const instance = basicLightbox.create(
	document.querySelector('#template')
)

Parameters:

• content {Node|String} Content of the lightbox.
• opts {?Object} An object of options.

Returns:

• {Object} The created instance.

Returns true when a lightbox is visible. Also returns true when a lightbox is currently in the process of showing/hiding and not fully visible/hidden, yet.

Example:

const visible = basicLightbox.visible()

Returns:

• {Boolean} Visibility of any lightbox.

Each basicLightbox instance has a handful of handy functions. Below are all of them along with a short description.

Shows a lightbox instance.

Examples:

instance.show()

instance.show(() => console.log('lightbox now visible'))

Parameters:

• cb(instance) {?Function} A function that gets executed as soon as the lightbox starts to fade in.

Closes a lightbox instance.

Examples:

instance.close()

instance.close(() => console.log('lightbox not visible anymore'))

Parameters:

• cb(instance) {?Function} A function that gets executed as soon as the lightbox has been faded out.

Returns true when the lightbox instance is visible. Also returns true when the lightbox is currently in the process of showing/hiding and not fully visible/hidden, yet.

Example:

const visible = instance.visible()

Returns:

• {Boolean} Visibility of lightbox.

Returns the DOM element/node associated with the instance.

Example:

const elem = instance.element()

	 */
	closable: true,
	/*

	 */
	className: '',

	onShow: (instance) => {},
	/*

	 * Returning false will prevent the lightbox from closing.
	 */
	onClose: (instance) => {}
}

Import src/styles/main.scss directly to customize the look of basicLightbox:

$basicLightbox__background: rgba(0, 0, 0, .8); // Background color
$basicLightbox__zIndex: 1000; // Stack order
$basicLightbox__duration: .4s; // Transition duration
$basicLightbox__timing: ease; // Transition timing

@import 'src/styles/main';
