Follow these steps to successfully build out a modal window.

First we'll create a button element that triggers the modal.

In this example well create a basic button with a unique Id to pass into the modal. Well use #trigger-modal in this example

<button class="gr-btn" id="trigger-modal">Open Modal</button>

Next add the <pearson-modal> tag after the closing <main id="main"></main> element.

Then add an attribute of triggerid to the modal with the value of the id of the <button> This tells the modal which button to listen to.

You need to place the modal element after the main tag.
<body>    <main id="main">        <button class="gr-btn" id="trigger-modal">Open Modal</button>    </main>
    // add the modal after the closing main tag    <pearson-modal triggerid="trigger-modal"> </pearson-modal></body>

Then, add any custom markup you want displayed in the modal. This can include any HTML5 element.

<body>    <main id="main">        <button class="gr-btn" id="trigger-modal">Open Modal</button>    </main>
    // add the modal after the closing main tag    <pearson-modal>        <p>Playground World</p>    </pearson-modal></body>

Finally, add an event listener on the button to trigger the modal.

<script>const button = document.querySelector('#trigger-modal'),modal = document.querySelector('pearson-modal');button.addEventListener('click', event => { = true})</script>

Important note: You can optionally build the modal programatically by creating a <pearson-modal> element and adding the required or optional attributes.



All these attributes are required.

triggeridStringRequiredThe unique ID of the button that opens the modal.


All these attributes are optional.

openBoolUnsetIf set true, modal opens. If attribute removed, close modal.
titletextStringModal TitleThe title of the modal.
footerBooleanfalseIf set, shows the Success and Cancel buttons.
successbtntextString'Save'The text to display in the Success button.
cancelbtntextString'Cancel'The text to display in the Cancel button.
hidecancelBooleanfalseHides the Cancel button completely
hidesuccessBooleanfalseHides the Success/CTA button completely
showonloadBoolfalseSet this attribute if you want to modal to fire without a button.


The pearson-modal component emits two different events:

successWill fire when the success button in the modal is pressed.
cancelWill fire when any button other than the success buton is pressed, or when the user closes the modal with the escape key.
const modal = document.querySelector('pearson-modal');
modal.addEventListener('success', () => {  // Do something});
modal.addEventListener('cancel', () => {  // Do something});

HTML Markup#

Do you want to use your own JS to make the modal function? No problem, use the markup below along with CSS to build a modal with your own JS.

Important note: You can follow the UXF guidelines to view the suggested functionality of the modal window.

Here are some basic practices to make sure the modal you build is accessible.
<div id="modalContainer" class="gr-modal-container">    <div id="modalOverlay"></div>    <div class="modal" role="dialog" aria-labelledby="dialog-heading" aria-describedby="dialog-description"         aria-modal="true">        <h2 id="dialog-heading" class="gr-h2">Modal Dialog Title</h2>        <div class="modal-body" id="dialog-description">                <p>Pass in JSX elements as children to the modal, You must pass in the text object with valid strings</p>        </div>        <div class="actions">            <button id="lastButton" class="gr-btn primary">Success Button</button>            <button id="firstButton" class="gr-btn">Cancel Button</button>        </div>    </div></div>
