+# Lightbox
+
+
+A responsive lightbox to be used in conjunction with e.g. a MDLEXT lightboard component.
+
+## Introduction
+The Material Design Lite Ext (MDLEXT) Lightbox displays an image filling the screen, and dimming out the rest of the web page.
+It acts as a modal dialog, using the `<dialog>` element as a container for the lightbox. The component uses
+the [Material Design Lite Card component](http://www.getmdl.io/components/index.html#cards-section) to provide a layout for the lightbox.
+
+## How to use the Google Chrome Dialog polyfill
+
+ 1. Install [Google Chrome Dialog polyfill](https://github.com/GoogleChrome/dialog-polyfill).
+```sh
+$ npm install --save dialog-polyfill
+```
+
+ 2. Use the polyfill in a static page.
+```html
+<!DOCTYPE html>
+<html>
+<head>
+ <title>Material Design Lite Extensions</title>
+ <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:regular,bold,italic,thin,light,bolditalic,black,medium&lang=en">
+ <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
+ <link rel="stylesheet" href="node_modules/dialog-polyfill/dialog-polyfill.css" />
+ <link rel="stylesheet" href="node_modules/material-design-lite/material.css" />
+ <link rel="stylesheet" href="node_modules/mdl-ext/lib/mdl-ext.min.css" />
+</head>
+<body>
+<div class="mdl-layout mdl-js-layout mdl-layout--fixed-drawer">
+ <main class="mdl-layout__content">
+ </main
+</div>
+<script type="text/javascript" src="node_modules/dialog-polyfill/dialog-polyfill.js" charset="utf-8"></script>
+<script type="text/javascript" src="node_modules/material-design-lite/material.min.js" charset="utf-8"></script>
+<script type="text/javascript" src="node_modules/mdl-ext/lib/mdl-ext.min.js" charset="utf-8"></script>
+</body>
+</html>
+```
+
+ 3. Use it in your (Webpack) build.
+
+ 3.1. Import `dialog-polyfill.css` in your main SASS file..
+```css
+@import '../node_modules/dialog-polyfill/dialog-polyfill.css';
+```
+
+ 3.2. Require `dialog-polyfill`.
+```javascript
+const dialogPolyfill = require('dialog-polyfill/dialog-polyfill');
+```
+
+ ... or import the `dialog-polyfill`.
+```javascript
+import { dialogPolyfill } from 'dialog-polyfill/dialog-polyfill';
+```
+
+>Adjust path to `node_modules` (libraries) according to where your files are located.
+>For more information about the dialog polyfill, refer to the [Google Chrome Dialog polyfill](https://github.com/GoogleChrome/dialog-polyfill) documentaion and the Material Design Lite [Dialog](http://www.getmdl.io/components/index.html#dialog-section) section.
+
+## To include a MDLEXT lightbox component
+ 1. Code a `<dialog>` element with `class="mdlext-dialog"` to display the lightbox as a modal dialog.
+```html
+<dialog class="mdlext-dialog">
+</dialog>
+```
+
+ 2. Code a `<div>` element with `class="mdlext-lightbox mdlext-js-lightbox mdl-card"` to hold the lightbox.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ </div>
+</dialog>
+```
+
+ 3. Code a `<div>` element with `class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast"` to hold the close dialog button.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ </div>
+ </div>
+</dialog>
+```
+
+ 4. Code a `<button>` element with `data-action="close"` and `class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect"` to display the close button. Add an `<i>` element inside the `<button>` element to hold the close icon.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ </div>
+</dialog>
+```
+
+ 5. Code a `<figure>` element with `class="mdl-card__media"` to hold the image and the image description.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ </figure>
+ </div>
+</dialog>
+```
+
+ 5. Inside the `<figure>` element code an empty `<img>` element and an empty `<figcaption>` element to hold the image and the image description.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ <img src="" alt>
+ <figcaption></figcaption>
+ </figure>
+ </div>
+</dialog>
+```
+
+
+ 6. Code a `<footer>` element with `class="mdl-card__actions"` to hold the image title and navigation buttons.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ <img src="" alt>
+ <figcaption></figcaption>
+ </figure>
+ <footer class="mdl-card__actions">
+ </footer>
+ </div>
+</dialog>
+```
+
+ 7. Code a `<div>` element with `class="mdl-card__supporting-text"` to hold the image title.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ <img src="" alt>
+ <figcaption></figcaption>
+ </figure>
+ <footer class="mdl-card__actions">
+ <div class="mdl-card__supporting-text">
+ </div>
+ </footer>
+ </div>
+</dialog>
+```
+
+ 8. Code a `<nav>` element to hold the navigation buttons.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ <img src="" alt>
+ <figcaption></figcaption>
+ </figure>
+ <footer class="mdl-card__actions mdl-card--border">
+ <div class="mdl-card__supporting-text">
+ </div>
+ <nav>
+ </nav>
+ </footer>
+ </div>
+</dialog>
+```
+
+
+ 9. Add your navigation buttons with `class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect"` inside the `<nav>` element.
+```html
+<dialog class="mdlext-dialog">
+ <div class="mdlext-lightbox mdlext-js-lightbox mdl-card">
+ <div class="mdl-card__menu mdl-color-text--white mdl-typography--body-2-color-contrast">
+ <button data-action="close" class="mdl-button mdl-button--icon mdl-js-button" title="Close">
+ <i class="material-icons">close</i>
+ </button>
+ </div>
+ <figure class="mdl-card__media">
+ <img src="" alt>
+ <figcaption></figcaption>
+ </figure>
+ <footer class="mdl-card__actions mdl-card--border">
+ <div class="mdl-card__supporting-text">
+ </div>
+ <nav>
+ <button data-action="first" class="mdl-button mdl-button--icon mdl-js-button" title="First">
+ <i class="material-icons">first_page</i>
+ </button>
+ <button data-action="prev" class="mdl-button mdl-button--icon mdl-js-button" title="Previous">
+ <i class="material-icons">chevron_left</i>
+ </button>
+ <button data-action="next" class="mdl-button mdl-button--icon mdl-js-button" title="Next">

+Add as many buttons as you like. To identify the button that trigger an custom event, you should assign each button a unique data-action attribute value.
+The data-action attribute will be emitted as a part of the custom event triggered when a button is clicked.

+ 10. Add an image and open the dialog.
+
+```javascript
+var dialog = document.querySelector('dialog');
+
+// A dialog element MUST be a child of document.body!!
+if(dialog.parentNode.tagName !== 'BODY') {
+ document.body.appendChild(dialog);
+}
+
+if (!('showModal' in dialog)) {
+ dialogPolyfill.registerDialog(dialog);
+}
+var lightbox = dialog.querySelector('.mdlext-lightbox');
+var img = lightbox.querySelector('img');
+var supportingText = lightbox.querySelector('.mdl-card__supporting-text');
+var imageDetails = lightbox.querySelector('figcaption');
+
+img.setAttribute("src", 'wiew-from-my-window.jpg');
+img.setAttribute("alt", 'View from my window');
+img.setAttribute("title", 'View from my window');
+img.setAttribute('data-img-url-prev', 'some-image.jpg');
+img.setAttribute('data-img-url-next', 'some-other-image.jpg');
+supportingText.innerHTML = 'View from my window';
+imageDetails.innerHTML = 'Photo taken from my window yesterday morning';
+
+if(!dialog.open) {
+ dialog.showModal();
+}
+```
+
+### Examples
+* See: [snippets/carousel.html](./snippets/lightbox.html)
+* TRy out [the live demo](http://leifoolsen.github.io/mdl-ext/demo/lightbox.html)
+
+## Keyboard interaction
+The lightbox interacts with the following keyboard keys.
+
+* `Left arrow` - Emits a custom event with action='prev'
+* `Right arrow` - Emits a custom event with action='next'
+* `Up arrow` - behaves the same as left arrow.
+* `Down arrow` - behaves the same as right arrow.
+* `End` - Emits a custom event with action='last'
+* `Home` - Emits a custom event with action='first'
+* `Space` - Emits a custom event with action='select'
+* `Esc` - Emits a custom event with action='cancel'
+
+## Mouse / Touch interaction
+* `Drag/Swipe left` - Emits a custom event with action='next'
+* `Drag/Swipe right` - Emits a custom event with action='prev'
+
+## Events
+The lightbox emits a custom **action** event when a button contained in the lightbox is clicked, an images is dragged or swiped,
+or if one of the keys `Arrow Left`, `Arrow Up`, `Arrow Right`, `Arrow Down`, `Home`, `End`, `Space` or `Esc` is pressed.
+The event has a detail object with the following content:
+```
+{
+ action, // one of: 'first', 'prev', 'next', 'last', 'select', 'close', 'cancel' -
+ // or any value assigned to a button action attribute (empty string if no action assigned)
+ source // the button instance that caused the event, or the lightbox element if a key triggered the event
+}
+```
+
+## Configuration options
+
+The MDLEXT CSS classes apply various predefined visual and behavioral enhancements to the lightbox.
+The table below lists the available classes and their effects.
+
+| MDLEXT class | Effect | Remarks |
+|--------------|--------|---------|
+| `mdlext-lightbox` | Defines a container as an MDLEXT lightbox component | Required on `<div>` element |
+| `mdlext-js-lightbox` | Assigns basic MDL behavior to lightbox | Required on `<div>` element |
+| `mdlext-lightbox__slider` | Displays previous, current and next image when dragging | Element added by component |
+| `mdlext-lightbox__slider__slide` | Holds an image to display when dragging | Element added by component |
+
+<!--
+| `mdlext-lightbox--sticky-footer` | Positions footer at bottom of screen | Optional on `mdlext-lightbox` element |
+-->
+
+| Attribute | Effect | Remarks |
+|-----------|--------|---------|
+| `data-img-url-prev` | Displays previous image when dragging | URL to previous image in a collection |
