WCAG 2.1 Level AA Compliance

• 1.3.1 Info and Relationships (Level A): Semantic HTML5 form elements with proper label associations using htmlFor/id attributes. ARIA roles and landmarks ensure screen readers understand form structure.
• 1.4.1 Use of Color (Level A): Password requirements use icons (✓/✗), text labels, and color together—never color alone. Error states include red borders, error icons, and descriptive text messages.
• 1.4.3 Contrast (Minimum) (Level AA): All text meets 4.5:1 contrast ratio minimum. Body text (slate-900 on white): 7.2:1, Primary buttons (white on indigo-600): 8.5:1, Error text (red-700): 6.8:1.
• 1.4.10 Reflow (Level AA): Responsive design from 320px to desktop. No horizontal scrolling required at 200% zoom. Content reflows naturally across all viewport sizes.
• 2.1.1 Keyboard (Level A): Complete keyboard navigation with Tab/Shift+Tab. Enter submits forms, Space toggles checkboxes and password visibility. No keyboard traps.
• 2.4.7 Focus Visible (Level AA): 2px indigo focus ring with 2px offset on all interactive elements. 4.5:1+ contrast against all backgrounds, clearly distinguishable from element borders.
• 2.5.5 Target Size (Level AAA - Exceeded): All interactive elements meet minimum 44×44px touch target size, exceeding WCAG Level AA requirements for improved mobile accessibility.
• 3.3.1 Error Identification (Level A): Errors identified with icons, red borders, and descriptive text. Field-specific messages appear inline. ARIA attributes ensure screen reader announcements.
• 3.3.2 Labels or Instructions (Level A): Persistent visible labels with icon affordances. Required field indicators (*) with screen reader text. Password requirements shown proactively with real-time validation.
• 4.1.2 Name, Role, Value (Level A): All form controls have accessible names via labels. ARIA attributes (aria-invalid, aria-describedby, aria-live) communicate state changes to assistive technologies.

Design Rationale

• Password Visibility Toggle: Allows users to verify their password entry, reducing errors. Button clearly labeled for screen readers.
• Real-time Password Strength Indicator: Provides immediate feedback on password requirements without waiting for form submission. Uses visual and text indicators.
• Skip to Main Content Link: Keyboard users can bypass navigation and go directly to the form, improving efficiency.
• Required Field Indicators: Visual (*) and screen reader-friendly indication of required fields helps users complete forms correctly.
• Inline Validation: Error messages appear directly below fields they relate to, making it clear what needs to be fixed.
• Clear Focus States: Prominent focus rings on all interactive elements help keyboard users track their position.
• Tab Accessibility: Login/Signup tabs use proper ARIA roles (tablist, tab, tabpanel) for screen reader navigation.
