### High Contrast Themes Implementation
|
|
Successfully implemented two new high contrast themes for low vision accessibility:
|
|
|
|
1. **High Contrast Light Theme** (`high-contrast-light`)
|
|
- Pure black text (#000000) on pure white backgrounds (#FFFFFF)
|
|
- 7:1+ contrast ratios (WCAG AAA compliant)
|
|
- Enhanced typography with 600-700 font weights
|
|
- 3px black borders for element definition
|
|
|
|
2. **High Contrast Dark Theme** (`high-contrast-dark`)
|
|
- Pure white text (#FFFFFF) on pure black backgrounds (#000000)
|
|
- 7:1+ contrast ratios (WCAG AAA compliant)
|
|
- Enhanced typography with 600-700 font weights
|
|
- 3px white borders for element definition
|
|
|
|
### Files Modified
|
|
1. **frontend/src/app/globals.css** - Added complete high contrast theme CSS variables and overrides
|
|
2. **frontend/src/app/layout.tsx** - Updated ThemeProvider to include new themes

|
|
- **Multiple Access Points**: Theme selector in navigation + footer accessibility buttons
|
|
- **Enhanced Focus Indicators**: 4px yellow outlines for keyboard navigation
|
|
- **Complete Text Visibility**: Fixed all invisible text issues (buttons, navigation, CTA sections)
|
|
- **WCAG AAA Compliance**: Maximum contrast ratios for low vision users
|
|
- **Performance Optimized**: CSS-only theme switching without JavaScript re-rendering
|
|
|
