Stop Shipping Inaccessible Code: Build WCAG-Compliant UIs by Default

You're tired of accessibility issues slipping into production. Of retrofitting components months later when compliance audits surface critical violations. Of spending entire sprints fixing accessibility debt that could have been prevented with the right development workflow.

The Hidden Cost of Accessibility-Last Development

Here's the reality: One in four adults in the US has a disability that impacts their web experience. Your current development process treats accessibility as an afterthought—something to "check later" or handle in a separate ticket. This approach costs you:

3-5x more effort to retrofit components versus building them accessibly from day one
Legal liability exposure from ADA and Section 508 violations (average settlement: $75,000+)
Lost revenue from 26% of your potential user base who can't effectively use your product
Developer frustration from constant context-switching between feature work and accessibility fixes

The core problem? Most teams lack a systematic approach to weave WCAG compliance directly into their development workflow.

A Complete Accessibility-First Development System

These Cursor Rules transform your codebase into an accessibility-compliant powerhouse. Instead of bolting on accessibility later, you'll build WCAG 2.1 AA compliance into every component, form, and interaction from the ground up.

What you get:

Automated WCAG validation integrated into your CI/CD pipeline with zero-tolerance for critical violations
Smart error handling that automatically creates accessible error states and focus management
Production-ready patterns for complex components (modals, forms, tables) with full keyboard navigation
Comprehensive testing strategy combining axe-core automation with targeted manual audits

This isn't just about avoiding lawsuits—it's about building better software that works for everyone while reducing your technical debt.

Transform Your Development Workflow

Before: The Accessibility Scramble

// Typical approach - accessibility as an afterthought
function LoginForm() {
  return (
    <div className="form">
      <div>Username</div>
      <input type="text" />
      <div>Password</div>
      <input type="password" />
      <button onClick={handleSubmit}>Login</button>
    </div>
  );
}
// Result: Screen readers can't navigate, no error handling, fails WCAG

After: Accessibility-First by Default

// With these rules - WCAG compliance built in
function LoginForm() {
  return (
    <form onSubmit={handleSubmit} aria-live="polite">
      <h1>Login to Your Account</h1>
      {errors.summary && (
        <div role="alert" id="error-summary">
          <h2>Please correct the following errors:</h2>
          <ul>
            {errors.fields.map(error => (
              <li key={error.field}>
                <a href={`#${error.field}`}>{error.message}</a>
              </li>
            ))}
          </ul>
        </div>
      )}
      
      <label htmlFor="username">Username</label>
      <input 
        id="username"
        type="text"
        aria-invalid={errors.username ? "true" : "false"}
        aria-describedby={errors.username ? "username-error" : undefined}
      />
      {errors.username && (
        <div id="username-error" role="alert">{errors.username}</div>
      )}
      
      <button type="submit">Login</button>
    </form>
  );
}
// Result: Full keyboard navigation, screen reader support, WCAG 2.1 AA compliant

Eliminate Accessibility Debt Forever

Automated Compliance Gates

Every pull request automatically runs comprehensive accessibility audits:

// Integrated into your test suite
describe('LoginForm Accessibility', () => {
  it('meets WCAG 2.1 AA standards', async () => {
    const { container } = render(<LoginForm />);
    const results = await axe(container);
    expect(results).toHaveNoViolations();
  });
});

Impact: Zero accessibility regressions reach production. Your CI/CD pipeline becomes an accessibility quality gate that prevents violations before they ship.

Smart Error Handling That Actually Works

// Automatic focus management and error announcements
const handleFormError = (errors: ValidationErrors) => {
  // Focus moves to error summary
  errorSummaryRef.current?.focus();
  
  // Screen readers announce errors
  setAriaLiveMessage(`${errors.length} errors found. Please review and correct.`);
  
  // Each field gets proper ARIA attributes
  return errors.map(error => ({
    ...error,
    ariaInvalid: true,
    ariaDescribedBy: `${error.field}-error`
  }));
};

Result: Users with disabilities get the same smooth error experience as everyone else. No more broken form flows or confused screen reader users.

Production-Ready Component Patterns

Build complex UI components that work perfectly with assistive technology:

// Modal with complete accessibility built in
export const Modal = forwardRef<HTMLDivElement, ModalProps>(
  ({ isOpen, onClose, title, children }, ref) => {
    const modalRef = useRef<HTMLDivElement>(null);
    
    useEffect(() => {
      if (isOpen) {
        // Trap focus inside modal
        modalRef.current?.focus();
        // Prevent body scroll
        document.body.style.overflow = 'hidden';
      }
      return () => {
        document.body.style.overflow = 'unset';
      };
    }, [isOpen]);

    return (
      <div 
        ref={modalRef}
        role="dialog"
        aria-modal="true"
        aria-labelledby="modal-title"
        tabIndex={-1}
      >
        <h2 id="modal-title">{title}</h2>
        {children}
      </div>
    );
  }
);

Real Developer Workflows: Daily Impact

Sprint Planning That Includes Everyone

## Acceptance Criteria (Generated automatically)
- [ ] All interactive elements reachable via keyboard
- [ ] Screen reader announces form errors clearly
- [ ] Color contrast meets 4.5:1 ratio for all text
- [ ] Component passes axe-core audit with 0 violations
- [ ] Focus management works correctly for dynamic content

Time Saved: 2-3 hours per story that would otherwise be spent writing accessibility acceptance criteria manually.

Code Reviews With Built-In Accessibility

Your PR automatically includes:

Accessibility impact assessment
Keyboard navigation demo video
Screen reader compatibility report
WCAG checkpoint verification

Developer Experience: No more "Did anyone test this with a screen reader?" questions. Accessibility validation happens automatically.

Component Library That's Accessible by Default

// Every component exports accessibility metadata
export const Button = {
  component: ButtonComponent,
  accessibility: {
    keyboardSupport: ['Enter', 'Space'],
    ariaRoles: ['button'],
    contrastRatio: '4.5:1',
    screenReaderTested: true
  }
};

Result: Your design system becomes a force multiplier for accessibility across all your products.
