Build an accessible modal with focus-trap-react

Creating an accessible modal involves using tools and techniques to ensure all users, including those with disabilities, can navigate the modal using only a keyboard. The focus-trap-react library is highlighted as an effective tool for trapping focus within a modal or other user interface components like dropdowns and tooltips, ensuring that user interaction is confined to the modal. The tutorial outlines the process of setting up a React project, installing the focus-trap-react package, and building a modal that maintains focus on interactive elements, like buttons and links, through keyboard navigation. It involves using React's useState and useRef hooks to manage modal visibility and focus behavior, customizing the focus trap with options such as onActivate, onDeactivate, and clickOutsideDeactivates. Testing with screen readers and ensuring the modal is properly labeled and keyboard-navigable is crucial for full accessibility, and additional libraries like react-aria-modal can be employed to further enhance accessibility features by aligning with WAI-ARIA practices.
