Build a React country explorer from semantic HTML first, then add ARIA only when native elements cannot express the interaction. React supports standard HTML and ARIA attributes; it does not automatically make a custom widget keyboard-accessible. A component structure that keeps each control’s name, state, and behavior together makes those responsibilities easier to understand and reuse.
Start with native HTML, not ARIA
Use an <a> for navigation to a country page, a <button> for an action, and a labeled form control for search or filtering. These elements communicate purpose to browsers and assistive technologies and provide familiar interaction behavior. React supports these standard HTML approaches, and its DOM elements accept ARIA attributes using the same names as HTML. React DOM common components
ARIA adds semantics such as roles, states, and properties when an interface needs them; it does not supply the interaction behavior. A custom element styled to look like a button does not become a working button simply because it has role="button". It still needs appropriate focus handling and keyboard behavior, among other implementation details. The W3C explains ARIA’s role in describing dynamic content and interface controls in its WAI-ARIA overview.

Choose component boundaries around explorer responsibilities
React lets developers compose interfaces from components, but it does not prescribe one architecture for a country explorer. A practical starting point is to separate the page shell, search and filter controls, results, selected-country details, and any map or other visualization. These are design choices, not requirements imposed by React.
#1 Best Overall
Keep a control’s accessible name, current state, and interaction behavior near the component that implements it. For example, a search component should own or receive the query value and expose a clearly labeled input; a result item should make its navigation or selection behavior clear. Share data or state at the narrowest level that supports the actual interactions, lifting it higher only when multiple parts of the interface need to coordinate.
React’s documentation describes components and ways to compose them, as well as sharing data between components. It does not establish a required country-explorer component tree or state-management pattern. React Quick Start
Make every interaction understandable by keyboard
For each control, identify what it does, what its accessible name is, what state it can have, and how a keyboard user reaches and operates it. Native controls usually provide a stronger starting point than recreating their behavior with generic elements.

- In-place actions: Use buttons for actions such as clearing filters or changing a displayed view.
- Search and filters: Use labeled native form controls where they fit the interaction, and ensure results or status changes are communicated appropriately.
- Custom widgets: If a map or other visualization needs a non-native interaction model, choose a specific pattern and implement its focus, keyboard behavior, accessible name, and state rather than relying on ARIA alone.
The W3C’s ARIA practices guidance is explicit: “Unlike native HTML form elements, browsers do not provide keyboard support for graphical user interface (GUI) components that are made accessible with ARIA; authors have to provide the keyboard support in their code.” WAI-ARIA Authoring Practices: Practices
Use APG patterns as guidance, not as a drop-in design system
The WAI-ARIA Authoring Practices Guide (APG) offers patterns and examples for common interface widgets. Consult the pattern that matches a custom interaction, then implement and test it in the context of your application. The APG cautions: “The APG is not a UI Design System.” Its examples are informative guidance, not a production-ready component library or a guarantee that an implementation will work for every user.

Automated accessibility checks can help catch technical issues, but they cannot establish that every explorer interaction is usable. Include keyboard testing and testing with assistive technology in the plan. React’s accessibility page is legacy documentation, but it makes the enduring point that technical checks should be combined with other checks, including screen-reader testing. React Accessibility
Test the actual paths a user takes: finding and operating search, changing filters, moving through results, opening a country detail, and using any custom visualization. Verify that focus remains visible and predictable, controls have understandable names and states, and updates do not leave keyboard or assistive-technology users unsure what changed.
