@magic-spells/modal-panel v0.1.1

Modal Panel Web Component

A lightweight, customizable Web Component for creating accessible modals. Ideal for dialogs, alerts, or content panels with smooth animations and accessibility features.

Features

• No dependencies
• Lightweight
• Follows accessibility best practices
• Smooth animations
• Uses aria attributes for accessibility

Installation

npm install @magic-spells/modal-panel

// Add to your JavaScript file
import '@magic-spells/modal-panel';

Or include directly in your HTML:

<script src="https://unpkg.com/@magic-spells/modal-panel"></script>

Usage

<button
	id="show-modal-button"
	aria-controls="modal-panel"
	aria-expanded="false">
	Open Modal
</button>

<modal-panel id="modal-panel" aria-hidden="true">
	<modal-overlay></modal-overlay>

	<modal-content>
		<button aria-label="Close Modal" data-action="hide-modal">
			&times;
		</button>

		<div>
			<h2>Modal Title</h2>
			<p>
				This is a demonstration of the modal panel component. Add your
				content here.
			</p>
		</div>
	</modal-content>
</modal-panel>

<script>
	const button = document.getElementById('show-modal-button');
	const modal = document.getElementById('modal-panel');

	button.addEventListener('click', () => modal.show());
</script>

How It Works

• The modal is initially hidden (aria-hidden="true").
• Clicking the button triggers the show() method, making the modal visible.
• Clicking the overlay or a close button (data-action="hide-modal") triggers the hide() method, closing the modal.
• Keyboard focus is automatically managed, moving to the first interactable element in the modal when it opens.

Customization

Styling

You can style the Modal Panel by overriding or extending the provided CSS:

modal-panel {
	/* Customize your modal panel */
}

modal-overlay {
	background-color: rgba(0, 0, 0, 0.5);
}

[data-action='hide-modal'] {
	font-size: 24px;
	color: #333;
}
