Web Component

You must include each Bento component's required CSS library before adding custom styles in order to guarantee proper loading. Or use the lightweight pre-uprgrade styles available inline. See Layout and Style.

Import via npm

npm install @bentoproject/lightbox

import {defineElement as defineBentoLightbox} from '@bentoproject/lightbox';
defineBentoLightbox();

Import via <script>

<script type="module" async src="https://cdn.ampproject.org/bento.mjs"></script>

        // set up button actions
        document.querySelector('#open-button').onclick = () => api.open();
        document.querySelector('#close-button').onclick = () => api.close();

Interactivity and API usage

Bento components are highly interactive through their API. The bento-lightbox component API is accessible by including the following script tag in your document:

await customElements.whenDefined('bento-lightbox');
const api = await lightbox.getApi();

Actions

The amp-lightbox API allows you to perform the following actions:

open()

Opens the lightbox.

api.open();

close()

Closes the lightbox.

api.close();

Events

The amp-lightbox API allows you to register and respond to the following events:

open

This event is triggered when the lightbox is opened.

lightbox.addEventListener('open', (e) => console.log(e));

close

This event is triggered when the lightbox is closed.

lightbox.addEventListener('close', (e) => console.log(e));

Layout and style

Each Bento component has a small CSS library you must include to guarantee proper loading without content shifts. Because of order-based specificity, you must manually ensure that stylesheets are included before any custom styles.

<link
  rel="stylesheet"
  type="text/css"
  href="https://cdn.ampproject.org/v0/bento-lightbox-1.0.css"
/>

Alternatively, you may also make the light-weight pre-upgrade styles available inline:

<style>
  bento-lightbox {
    display: none !important;
  }
</style>

Attributes

id

A unique identifier for the lightbox.

hidden

Must be present when the lightbox is closed and the contents should not be displayed, such as on first layout.

animation

Defines the style of animation for opening the lightbox. By default, this will be set to fade-in. Valid values are fade-in, fly-in-bottom, and fly-in-top.

scrollable

When the scrollable attribute is present, the content of the lightbox can scroll when overflowing the height of the lightbox.

API Example

<link
      rel="stylesheet"
      type="text/css"
      href="https://cdn.ampproject.org/v0/bento-lightbox-1.0.css"
    />
    <script
      type="module"
      async
      src="https://cdn.ampproject.org/bento.mjs"
    ></script>
    <script nomodule src="https://cdn.ampproject.org/bento.js"></script>
    <script
      type="module"
      async
      src="https://cdn.ampproject.org/v0/bento-lightbox-1.0.mjs"
    ></script>
    <script
      nomodule
      async
      src="https://cdn.ampproject.org/v0/bento-lightbox-1.0.js"
    ></script>

</head>

<bento-lightbox id="my-lightbox" hidden>
      Lightboxed content
      <button id="close-button">Close lightbox</button>
    </bento-lightbox>
    <button id="open-button">Open lightbox</button>
    <script>
      (async () => {
        const lightbox = document.querySelector('#my-lightbox');
        await customElements.whenDefined('bento-lightbox');
        const api = await lightbox.getApi();

        // set up button actions
        document.querySelector('#open-button').onclick = () => api.open();
        document.querySelector('#close-button').onclick = () => api.close();
      })();
    </script>

Preact/React Component

Import via npm

npm install @bentoproject/lightbox

import React from 'react';
import {BentoLightbox} from '@bentoproject/lightbox/react';
import '@bentoproject/lightbox/styles.css';
function App() {
  return (
    <BentoLightbox
      id="lightbox"
      closeButtonAs={(props) => (
        <button {...props} aria-label="Close my fancy lightbox">
          Close!
        </button>
      )}
    >
      <p>Hello World</p>
    </BentoLightbox>
  );
}

Layout and style

Container type

The BentoLightbox component has a defined layout size type. To ensure the component renders correctly, be sure to apply a size to the component and its immediate children (slides) via a desired CSS layout (such as one defined with height, width, aspect-ratio, or other such properties). These can be applied inline:

<BentoLightbox style={{width: 300, height: 200}}></BentoLightbox>

Or via className:

<BentoLightbox className="custom-styles"></BentoLightbox>

.custom-styles {
  height: 100px;
  width: 100%;
}

Props

animation

Animation used to display the lightbox. Options are fade-in, fly-in-top or fly-in-bottom, Default is fade-in.

children

The content to show within this lightbox.

closeButtonAs

A prop which takes a function (as a render prop) to specify a custom close button.

onBeforeOpen

A prop which takes a function which is executed before the lightbox is opened.

onAfterOpen

A prop which takes a function which is executed after the lightbox is opened.

onAfterClose

A prop which takes a function which is executed after the lightbox is closed.
