When building modals and overlays with Alpine.js, you need to consider more than just showing and hiding content. Focus management and accessibility are essential for creating dialogs that everyone can use. You should ensure that when a modal opens, keyboard focus moves to the modal so users who rely on keyboards or assistive technology can interact with it. While Alpine.js does not provide focus management out of the box, you can use plugins like @alpinejs/focus or handle focus in your own code using JavaScript. Always make sure that pressing the Escape key closes the modal, and that focus is restored to the element that opened the modal when it closes. Mark your modal with role="dialog" and aria-modal="true" to help screen readers understand the context. By following these practices, your modals will be more usable and accessible for everyone.
