Most React developers assume accessibility is handled by the framework or the component library they use. JSX looks semantic, popular UI kits advertise built-in accessibility, and modern browsers are expected to fill in the gaps. If a component renders correctly and responds to user input, accessibility is rarely questioned.
But React applications are usually tested the same way they are built, visually, with a mouse, and on a single machine. Screen readers, keyboard-only navigation, and focus behavior are often outside the normal development workflow. As a result, accessibility failures surface only after deployment or user feedback.
What I have seen repeatedly is that React’s abstractions make these gaps easy to miss. React manages UI state well, but it does not manage interaction context, focus order, or announcements for assistive technologies.
Overview
What Is Accessibility in React?
Accessibility in React focuses on building user interfaces that everyone can use, including people with disabilities who rely on assistive technologies such as screen readers and keyboard navigation. React supports standard web accessibility practices and provides features that help manage dynamic content effectively.
Core Accessibility Practices in React
- Semantic HTML: Use appropriate HTML elements such as <button>, <h1>, and <nav> to convey meaning and structure to assistive technologies. Avoid using non-semantic elements like <div> for interactive components because they do not provide built-in accessibility features such as keyboard focus.
- ARIA Labels: When semantic HTML is not sufficient, use WAI-ARIA roles and attributes such as aria-label and role=”alert” to add meaning to dynamic content and custom components.
- Keyboard Navigation: Ensure all interactive elements can be accessed and operated using only a keyboard. Many users, including those with motor disabilities and screen reader users, depend on keyboard navigation.
- Color Contrast and Readability: Maintain sufficient contrast between text and background and use readable font sizes in line with WCAG compliance levels to support users with visual impairments.
React-Specific Accessibility Practices
- Focus Management: React’s dynamic rendering can disrupt natural focus order when elements are added or removed from the DOM. Use hooks like useRef and useEffect to manage focus intentionally, such as moving focus to a modal input or returning focus after form submission.
- Using Fragments: Use <React.Fragment> or the shorthand <> </> to group elements without adding unnecessary wrapper elements. This helps maintain a clean and logical DOM structure for screen readers.
- Accessible Forms: Explicitly associate labels with form controls using the htmlFor attribute in React. This ensures assistive technologies can correctly identify the purpose of each input.
- Accessible Error Handling: Communicate validation errors and status messages clearly. Use aria-live regions to announce dynamic updates so screen reader users are informed when content changes.
In this guide, I break down where accessibility fails in real React applications, why those failures slip through development, and how to fix them without slowing delivery.
What Is Accessibility in React?
Accessibility in React means building React user interfaces that can be used by everyone, including people who rely on assistive technologies such as screen readers and keyboards.
React applications still render HTML, and assistive technologies interact with the DOM, so the same web accessibility fundamentals apply, including semantic structure, keyboard support, and clear communication of content and state.
What makes accessibility more complex in React is its reliance on client-side rendering and state-driven updates. Content can change without a page reload, and unless those changes are handled intentionally, assistive technologies may not receive the necessary context. This can lead to experiences that appear functional visually but are confusing or unusable for some users.
For example, a screen reader may not announce a route change, a new error message, or a modal opening, and keyboard focus can remain on an element that no longer exists after a state update.
Why Accessibility Is Important for React Applications
React applications are built around dynamic state changes, reusable components, and client-side routing. These patterns improve user experience, but they also make accessibility failures easier to introduce and harder to detect during development.
This is why accessibility matters specifically in React:
- Dynamic UI updates can break context: State-driven changes such as inline validation errors, route transitions, or conditional rendering are not automatically announced to assistive technologies, which can leave users unaware that anything has changed.

- Custom components often replace native behavior: Replacing native elements with custom components can remove built-in keyboard support, roles, and focus handling unless these behaviors are explicitly reimplemented.

- Focus is not managed automatically: React does not track or restore focus when components mount, unmount, or re-render, which can cause keyboard users to lose their place during common interactions like form submissions or modal dialogs.
- Accessibility issues surface late: Many React accessibility problems only appear when testing with keyboards or screen readers, which often happens after features are complete or in production.
How to Make React Applications Accessible
Accessibility in React works best when it is applied deliberately, not as a final pass. The steps below reflect a practical workflow React developers can follow during everyday development.
Step 1: Start with semantic HTML before creating components
Use native HTML elements whenever possible and wrap them into components instead of recreating behavior with generic elements. For example, build on <button> and <input> rather than styling <div> elements to look interactive.
Step 2: Design keyboard behavior before styling
Ensure every interactive element supports keyboard accessibility and can be reached and operated without a mouse. Test tab order early and confirm that actions such as opening menus, submitting forms, and closing dialogs work smoothly with only the keyboard.
Step 3: Manage focus during UI changes
When content is added or removed, move focus intentionally. Use useRef and useEffect to shift focus to newly opened modals, error messages, or primary actions, and return focus to a logical place when the interaction ends.
Step 4: Make dynamic updates perceivable
For content that updates without a page reload, such as error messages or status changes, ensure those updates are announced. Use ARIA live regions sparingly to communicate changes that users would otherwise miss.
Step 5: Structure components for screen readers
Maintain a logical heading order, avoid unnecessary wrapper elements, and use fragments where appropriate to keep the DOM structure clean and understandable.
Step 6: Validate accessibility during development
Test components with a keyboard and a screen reader as part of development, not just at the end. Catching focus issues and missing announcements early prevents costly rework later.

Using ARIA Roles in React for Better Accessibility
ARIA plays a specific role in React applications because many UI patterns are built with custom components and dynamic updates. When native HTML semantics cannot fully describe an interaction, ARIA helps communicate intent and state to assistive technologies.
That said, ARIA in React works best when applied deliberately and sparingly. Here is how to use it correctly in real React components.
Step 1: Confirm that semantic HTML is not enough
Before adding any ARIA attributes, verify that the component cannot be implemented using native elements alone. For example, a native <button> already provides role, keyboard support, and focus behavior, so adding role=”button” is unnecessary and often harmful.
Step 2: Use ARIA to describe state, not appearance
ARIA is most effective when it communicates state changes, not styling. For interactive components such as toggles, accordions, or menus, expose state using attributes like aria-expanded, aria-pressed, or aria-selected, and update them in sync with React state.
Step 3: Apply ARIA roles only to custom components
When building components like modals, tabs, or dropdowns that do not map cleanly to native HTML, use appropriate roles such as dialog, tablist, or menu. Ensure the role matches the expected keyboard and interaction model, not just the visual design.
Step 4: Announce dynamic content intentionally
For content that updates without user focus, such as error messages or async status updates, use aria-live regions. Choose the correct politeness level so updates are announced at the right time without overwhelming screen reader users.
Step 5: Keep ARIA and focus behavior aligned
ARIA roles do not manage focus automatically. When using roles like dialog or alert, explicitly move focus to the relevant element and trap it where necessary. React hooks such as useRef and useEffect are essential for keeping focus and ARIA state in sync.
Step 6: Test ARIA behavior with real assistive technologies
ARIA correctness cannot be validated by visual inspection alone. Test components using screen readers and keyboard navigation to confirm that roles, states, and announcements behave as intended across browsers.
How to Test React Accessibility in 2026
Testing accessibility in React needs to happen during development and not only after features are complete. React applications rely on dynamic rendering and shared components, so accessibility issues often appear while code is being written and reused across the application.
Platforms like BrowserStack Accessibility DevTools bring accessibility testing into everyday React workflows. Instead of treating accessibility as a separate QA step, developers can test components as they build them and validate accessibility changes alongside functional updates.
Here are the key features that support practical React accessibility testing:
- IDE-Based Accessibility Feedback: Validate accessibility directly inside the editor while writing JSX and component logic and catch issues early without switching tools.
- Actionable Fix Guidance: Apply clear fixes for detected issues by correcting ARIA usage, improving label associations, and resolving focus behavior tied to component state.
- Pre-Commit and CI Validation: Run accessibility checks before code is merged and enforce standards by blocking inaccessible components from entering the codebase.
- React and React Native Coverage: Test accessibility consistently across component-driven architectures and shared UI patterns without introducing separate workflows.
Common Accessibility Mistakes in React Applications
React abstractions often encourage building UI through reusable components and state-driven logic. When accessibility is not considered during component design, the resulting issues tend to repeat across the application and are difficult to fix later.
The following mistakes are commonly introduced in React codebases:
- Replacing native interactive elements with div or span: Click handlers are frequently attached to non-semantic elements, which removes built-in keyboard support, focus behavior, and screen reader roles, requiring extensive manual fixes that are often incomplete.

- Relying on visual state instead of programmatic state: Components visually show expanded, selected, or active states, but React state changes are not reflected through ARIA attributes, so assistive technologies never receive those updates.
- Breaking focus order during re-renders: Conditional rendering and dynamic DOM updates can cause focus to reset or jump unpredictably, especially in modals, drawers, and inline editors.
- Rendering error messages without announcements: Validation errors and status updates appear in the UI, but screen reader users are not notified because live regions or proper roles are missing.
Accessibility Best Practices for React Applications
Most accessibility issues in React are not caused by missing tools but by missing patterns. Establishing consistent, component-level practices prevents these issues from spreading.
These practices help build accessible React components from the start:
- Use semantic HTML as the foundation of every component: Start with native elements like button, input, fieldset, and nav, and only introduce custom behavior when native functionality is insufficient.
- Treat focus as part of component state: Explicitly define focus entry and exit points for interactive components using refs and lifecycle effects, especially after state-driven DOM changes.
- Bind accessibility attributes to React state: Keep ARIA attributes, roles, and labels in sync with component state so visual and non-visual users receive the same information at the same time.
- Announce dynamic changes intentionally: Use aria-live, role=”alert”, or status regions to ensure React-driven updates such as errors, confirmations, and loading states are communicated clearly.
Conclusion
React enables teams to build complex interfaces quickly, but accessibility still requires deliberate effort. Issues related to structure, focus, and keyboard interaction often appear repeatedly across components when they are not handled early. Treating accessibility as part of routine React development helps prevent these issues from becoming embedded in the application.
BrowserStack Accessibility DevTools fits naturally into React development by enabling accessibility checks during coding and review. Teams can identify issues before components are merged and enforce accessibility standards consistently. This reduces dependence on late-stage audits and helps maintain accessibility as the application grows.
