Accessibility in Syncfusion® React Components
2 Feb 202622 minutes to read
Accessibility Overview
Accessibility ensures user interface components are usable by people with disabilities. This includes high-contrast themes, readable text, alternative text for images, and controls that support keyboard navigation and assistive technologies such as screen readers.
Accessibility Standards
A component is considered accessible when it conforms to established standards that ensure usability for people with disabilities. Syncfusion® React components adhere to the following key standards:
ADA (Americans with Disabilities Act)
ADA is a comprehensive civil rights law prohibiting discrimination based on disability. It ensures equal access and opportunities in digital experiences for people with disabilities.
WCAG 2.2 (Web Content Accessibility Guidelines)
WCAG 2.2 provides internationally recognized guidelines from the World Wide Web Consortium (W3C) to make web content accessible. It defines principles and success criteria organized under four core principles: Perceivable, Operable, Understandable, and Robust.
Section 508
Section 508 establishes U.S. federal requirements for electronic and information technology accessibility. These standards, aligned with WCAG, apply to federal agencies and ensure accessible digital content for people with disabilities.
WAI-ARIA (Web Accessibility Initiative - Accessible Rich Internet Applications)
WAI-ARIA supplies technical specifications to improve accessibility of dynamic content and rich internet applications. It defines roles, states, and properties that enhance compatibility with assistive technologies.
Keyboard Navigation
Keyboard navigation enables users to interact with interfaces using only a keyboard. This capability is essential for people who cannot use a mouse or other pointing devices.
Syncfusion® React components comply with these standards to deliver an inclusive user experience.
Accessibility Compliance
Syncfusion® React components implement recognized accessibility standards and specifications to provide an intuitive experience for users with disabilities.
Compliance Methodologies
Syncfusion® applies the following approaches to validate and maintain accessibility:
WAI-ARIA Pattern Implementation
Components follow WAI-ARIA Authoring Practices to implement appropriate ARIA roles, states, and properties, ensuring consistent behavior with assistive technologies.
Manual and Automated Testing
- Manual Testing: Components are tested with screen readers including Narrator (Windows) and VoiceOver (macOS) to confirm accurate announcements and interaction flows.
- Automated Testing: Tools such as accessibility-checker and axe-core detect and help resolve violations.
ARIA Attribute Management
Each component receives a suitable role attribute and dynamically updates ARIA attributes in accordance with WCAG 2.2 requirements, accurately reflecting state changes to assistive technologies.
Accessibility Features
Syncfusion® React components incorporate the following accessibility features:
Screen Reader Support
Components conform to WAI-ARIA standards and are compatible with major screen readers, including:
Right-to-Left Support
Right-to-Left (RTL) layout support enables effective communication in languages such as Arabic, Hebrew, and Persian. For details, see the Right-to-Left documentation.
Color Contrast
Predefined themes satisfy WCAG 2.2 Level AA contrast ratios (4.5:1 for normal text and 3:1 for large text). Custom themes should be validated to maintain these ratios.
Mobile Device Support
Components are fully responsive, adapt to different screen sizes and orientations, and provide touch-friendly interactions, improving accessibility on mobile devices.
Keyboard Navigation Support
Comprehensive keyboard support allows navigation and interaction without a mouse. Standard patterns include:
- Tab / Shift + Tab: Move focus forward/backward
- Enter / Space: Activate buttons and interactive elements
- Arrow Keys: Navigate within lists, grids, menus, and similar controls
- Escape: Close dialogs, popups, and overlays
- Home / End: Jump to first/last item in lists and grids
Ensuring Accessibility
Syncfusion® maintains accessibility through rigorous testing and ongoing refinement.
Automated Testing
Tools such as accessibility-checker and axe-core continuously scan components for compliance issues and suggest fixes.
Manual Testing
Manual evaluation with screen readers (Narrator, VoiceOver) verifies correct labeling, state announcements, and interaction behavior for assistive technology users.
Continuous Improvement
Accessibility is enhanced through:
- Regular internal audits
- User-reported issues and feedback
- Alignment with evolving standards
- Advances in assistive technology
Voluntary Product Accessibility Template (VPAT)
The Voluntary Product Accessibility Template (VPAT) documents conformance to accessibility standards such as Section 508, WCAG 2.2, and EN 301 549.
