# Dark Mode & Modern UI
|
|
|
|
Easy on the eyes, day or night. Toggle between light and dark themes to match your preference. The clean, modern interface makes managing complex setups feel simple.
|
|
|
|
## Overview
|
|
|
|
Charon's interface is built with **Tailwind CSS v4** and a modern React component library. Dark mode is the default, with automatic system preference detection and manual override support.
|
|
|
|
### Design Philosophy
|
|
|
|
- **Dark-first**: Optimized for low-light environments and reduced eye strain
|
|
- **Semantic colors**: Consistent meaning across light and dark modes
|
|
- **Accessibility-first**: WCAG 2.1 AA compliant with focus management
|
|
- **Responsive**: Works seamlessly on desktop, tablet, and mobile
|
|
|
|
## Why a Modern UI Matters
|
|
|
|
| Feature | Benefit |
|
|
|---------|---------|
|
|
| **Dark Mode** | Reduced eye strain during long sessions |
|
|
| **Semantic Tokens** | Consistent, predictable color behavior |
|
|
| **Component Library** | Professional, polished interactions |
|
|
| **Keyboard Navigation** | Full functionality without a mouse |
|
|
| **Screen Reader Support** | Accessible to all users |
|
|
|
|
## Theme System
|
|
|
|
### Color Tokens
|
|
|
|
Charon uses semantic color tokens that automatically adapt:
|
|
|
|
| Token | Light Mode | Dark Mode | Usage |
|
|
|-------|------------|-----------|-------|
|
|
| `--background` | White | Slate 950 | Page backgrounds |
|
|
| `--foreground` | Slate 900 | Slate 50 | Primary text |
|
|
| `--primary` | Blue 600 | Blue 500 | Actions, links |
|
|
| `--destructive` | Red 600 | Red 500 | Delete, errors |
|
|
| `--muted` | Slate 100 | Slate 800 | Secondary surfaces |
|
|
| `--border` | Slate 200 | Slate 700 | Dividers, outlines |
|
|
|
|
### Switching Themes
|
|
|
|
1. Click the **theme toggle** in the top navigation
|
|
2. Choose: **Light**, **Dark**, or **System**
|
|
3. Preference is saved to local storage
|
|
|
|
## Component Library
|
|
|
|
### Core Components
|
|
|
|
| Component | Purpose | Accessibility |
|
|
|-----------|---------|---------------|
|
|
| **Badge** | Status indicators, tags | Color + icon redundancy |
|
|
| **Alert** | Notifications, warnings | ARIA live regions |
|
|
| **Dialog** | Modal interactions | Focus trap, ESC to close |
|
|
| **DataTable** | Sortable data display | Keyboard navigation |
|
|
| **Tooltip** | Contextual help | Delay for screen readers |
|
|
| **DropdownMenu** | Action menus | Arrow key navigation |
|
|
|
|
### Status Indicators
|
|
|
|
Visual status uses color AND icons for accessibility:
|
|
|
|
- ✅ **Online** - Green badge with check icon
|
|
- ⚠️ **Warning** - Yellow badge with alert icon
|
|
- ❌ **Offline** - Red badge with X icon
|
|
- ⏳ **Pending** - Gray badge with clock icon
|
|
|
|
## Accessibility Features
|
|
|
|
### WCAG 2.1 Compliance
|
|
|
|
- **Color contrast**: Minimum 4.5:1 for text, 3:1 for UI elements
|
|
- **Focus indicators**: Visible focus rings on all interactive elements
|
|
- **Text scaling**: UI adapts to browser zoom up to 200%
|
|
- **Motion**: Respects `prefers-reduced-motion`
|
|
|
|
### Keyboard Navigation
|
|
|
|
| Key | Action |
|
|
|-----|--------|
|
|
| `Tab` | Move between interactive elements |
|
|
| `Enter` / `Space` | Activate buttons, links |
|
|
| `Escape` | Close dialogs, dropdowns |
|
|
| `Arrow keys` | Navigate within menus, tables |
|
|
|
|
### Screen Reader Support
|
|
|
|
- Semantic HTML structure with landmarks
|
|
- ARIA labels on icon-only buttons
|
|
- Live regions for dynamic content updates
|
|
- Skip links for main content access
|
|
|
|
## Customization
|
|
|
|
### CSS Variables Override
|
|
|
|
Advanced users can customize the theme via CSS:
|
|
|
|
```css
|
|
/* Custom brand colors */
|
|
:root {
|
|
--primary: 210 100% 50%; /* Custom blue */
|
|
--radius: 0.75rem; /* Rounder corners */
|
|
}
|
|
```
