# Windows 3.1 Web Designer

Creates modern 2026 web applications with authentic Windows 3.1 aesthetic. Not recreating 1992—**extrapolating Win31 to modern contexts**: AI assistants as Cue Card systems, mobile as pocket organizers, responsive as tiled MDI windows.

## When to Use

**Use for:**
- Web apps with Win31 authenticity (documentation sites, retro dashboards)
- AI chatbot interfaces (Cue Card-style assistants, wizard dialogs)
- Mobile-responsive Win31 UIs (pocket computing paradigm)
- Program Manager navigation patterns
- Tiled/cascading window layouts
- MDI (Multiple Document Interface) applications
- Hotdog Stand mode easter eggs

**Do NOT use for:**
- Windows 95 aesthetic → use **windows-95-web-designer** (gradients, Start menu, taskbar)
- Vaporwave/synthwave → use **vaporwave-glassomorphic-ui-designer** (neons, gradients)
- macOS/iOS styling → use **native-app-designer**
- Flat/Material design → use **web-design-expert**

## Win31 vs Win95: Critical Differences

| Feature | Windows 3.1 | Windows 95 |
|---------|-------------|------------|
| Title bar | **Solid navy** (#000080) | Gradient (dark→light blue) |
| Window controls | **Single menu button** | Three buttons (−, □, ×) |
| Navigation | **Program Manager** | Start Menu + Taskbar |
| Fonts | **Bitmap/VT323** | MS Sans Serif, Tahoma |
| Icons | **32×32 flat** | 32×32 with drop shadow |
| Depth | **Bevels only** | Bevels + subtle gradients |
| AI style | **Cue Cards, Wizards** | Clippy character |

## Core Design System

### Color Palette

| Color | Hex | CSS Variable | Usage |
|-------|-----|--------------|-------|
| System Gray | #c0c0c0 | `--win31-gray` | THE primary background |
| Dark Gray | #808080 | `--win31-dark-gray` | Shadows, pressed states |
| Light Gray | #dfdfdf | `--win31-light-gray` | Highlights |
| Navy | #000080 | `--win31-navy` | Title bar (SOLID, no gradient) |
| Teal | #008080 | `--win31-teal` | Desktop, links, highlights |
| White | #ffffff | `--win31-white` | Beveled highlights, inputs |
| Black | #000000 | `--win31-black` | Beveled shadows, borders |

### The Win31 Title Bar (SOLID)

**THE signature Win31 element** - solid navy, no gradient:

```css
.win31-titlebar {
  background: #000080; /* SOLID - never a gradient! */
  color: white;
  font-family: 'VT323', 'Courier New', monospace;
  font-weight: bold;
  font-size: 11px;
  padding: 3px 6px;
  display: flex;
  align-items: center;
  justify-content: space-between;
}

.win31-titlebar-inactive {
  background: #808080; /* Solid dark gray when inactive */
}
```

### Window Control Button (Single)

Win31 has ONE control button (not Win95's three):

```css
.win31-control-btn {
  width: 18px;
  height: 14px;
  background: var(--win31-gray);
  border: none;
  font-size: 8px;
  font-family: var(--font-pixel);

  /* 3D bevel - outset */
  box-shadow:
    inset -1px -1px 0 var(--win31-black),
    inset 1px 1px 0 var(--win31-white),
    inset -2px -2px 0 var(--win31-dark-gray),
    inset 2px 2px 0 var(--win31-light-gray);
}

.win31-control-btn:active {
  box-shadow:
    inset 1px 1px 0 var(--win31-black),
    inset -1px -1px 0 var(--win31-white);
}
```

### The Sacred Rule: Beveled Borders

**OUTSET (Raised)** - Buttons, toolbars:
- Top/Left border: WHITE
- Bottom/Right border: BLACK
- Inner: light-gray TL, dark-gray BR

**INSET (Sunken)** - Text fields, content areas:
- Top/Left border: DARK GRAY
- Bottom/Right border: WHITE
- Inner: black TL, light-gray BR

### Typography

| Use | Font | Fallback | Size |
|-----|------|----------|------|
| UI Labels | VT323 | Courier New | 12px |
| Title bars | VT323 Bold | Courier New Bold | 11px |
| Headings | Press Start 2P | VT323 | 14px |
| Code | IBM Plex Mono | Courier Prime | 12px |

**Web font stack:**
```css
:root {
  --font-win31-ui: 'VT323', 'Courier New', monospace;
  --font-win31-pixel: 'Press Start 2P', 'VT323', monospace;
  --font-win31-code: 'IBM Plex Mono', 'Courier Prime', monospace;
}
```

## Modern Extrapolations

### AI Chatbots: The Cue Card Paradigm

Win31 would present AI as a **modal wizard system**, not an animated character:

```
┌─ AI Assistant ──────────────────────[─]─┐
│                                          │
│  ┌────────────────────────────────────┐  │
│  │  What would you like help with?    │  │
│  │                                    │  │
│  │  ○ Writing a document              │  │
│  │  ○ Working with files              │  │
│  │  ○ Setting up your system          │  │
│  │  ○ Learning Windows basics         │  │
│  └────────────────────────────────────┘  │
│                                          │
│         [  OK  ]  [ Cancel ]  [ Help ]   │
└──────────────────────────────────────────┘
```

**Key patterns:**
- No animated characters (pre-Clippy)
- One question at a time (modal)
- Radio button/numbered choices
- Step-by-step wizard indicators
- Cue Cards floating alongside app

### Mobile: The Pocket Computing Paradigm

Win31 on mobile extrapolates to **pocket organizer with Program Manager**:

```
┌────────────────────────────┐
│ ■ Program Manager ─ 10:45  │  ← Title bar with time
├────────────────────────────┤
│ ╔════════════════════════╗ │
│ ║ Main                  ║ │
│ ╠════════════════════════╣ │
│ ║  ┌───┐   ┌───┐        ║ │
│ ║  │📁│   │📝│        ║ │  ← Program group
│ ║  │Mgr│   │Wrt│        ║ │
│ ║  └───┘   └───┘        ║ │
│ ╚════════════════════════╝ │
├────────────────────────────┤
│ [ Window ]  [ Help ]       │  ← Menu bar bottom
└────────────────────────────┘
```

**Key patterns:**
- Program Manager is navigation (not Start menu)
- One window at a time (modal stack)
- Dialog stack pattern (overlays cascade)
- Menu bar at bottom for touch
- Swipe left = close window

### Responsive: MDI as Breakpoints

Win31 used Multiple Document Interface. Apply this:

| Breakpoint | Win31 Metaphor | Layout |
|------------|----------------|--------|
| Mobile (<640px) | Pocket computing | Single window, modal dialogs |
| Tablet (640-1024px) | Laptop | Cascading windows |
| Desktop (>1024px) | Full desktop | Tiled MDI windows |

### Theming: Hotdog Stand and Beyond

Windows 3.1 had limited but memorable themes:

```css
/* Hotdog Stand (the infamous red/yellow) */
[data-theme="hotdog-stand"] {
  --win31-gray: #ff0000;
  --win31-dark-gray: #800000;
  --win31-light-gray: #ff8080;
  --win31-navy: #ffff00;
  --win31-title-text: #ff0000;
}

/* Monochrome (high contrast) */
[data-theme="monochrome"] {
  --win31-gray: #ffffff;
  --win31-dark-gray: #000000;
  --win31-light-gray: #ffffff;
  --win31-navy: #000000;
  --win31-teal: #000000;
}
```

## Anti-Patterns

### Anti-Pattern: Title Bar Gradients

**Novice thinking**: "Win31 has blue title bars like Win95"
**Reality**: Win31 has SOLID navy. Gradient is Win95 only.
**Instead**: `background: #000080` (never `linear-gradient`)

### Anti-Pattern: Three Window Buttons

**Novice thinking**: "Windows has minimize, maximize, close"
**Reality**: Win31 has a SINGLE menu button (−). The three-button pattern is Win95.
**Instead**: One button that opens a system menu

### Anti-Pattern: Start Menu/Taskbar

**Novice thinking**: "Windows navigation = Start button"
**Reality**: Win31 uses Program Manager. No taskbar, no Start.
**Instead**: Program groups with cascading/tiled windows

### Anti-Pattern: Neon Colors

**Novice thinking**: #00d4ff, #ff00ff for retro feel
**Reality**: This is vaporwave, not Win31
**Instead**: Muted palette: teal (#008080), navy (#000080), gray (#c0c0c0)

### Anti-Pattern: Rounded Corners

**Novice thinking**: `border-radius: 8px` for friendly UI
**Reality**: Win31 has sharp 90° corners everywhere
**Instead**: No border-radius (or 0)

### Anti-Pattern: Blur Effects

**Novice thinking**: `backdrop-filter: blur(10px)`, soft shadows
**Reality**: Win31 has no blur—only hard-edge bevels
**Instead**: Sharp bevel shadows: `box-shadow: 4px 4px 0 #000`

### Anti-Pattern: Dark Backgrounds

**Novice thinking**: Dark mode = #1a1a2e backgrounds
**Reality**: Win31 is LIGHT. System gray (#c0c0c0) everywhere.
**Instead**: Light gray base with teal desktop

### Anti-Pattern: Clippy-Style Characters

**Novice thinking**: Win31 had assistant characters
**Reality**: Clippy came with Office 97 (Win95 era). Win31 used Cue Cards.
**Instead**: Modal dialogs, step-by-step wizards, floating help cards

## The Quick Test

If your component has:
- ❌ Any gradient title bars → NOT Win31 (that's Win95)
- ❌ Three window buttons → NOT Win31 (that's Win95)
- ❌ Start menu or taskbar → NOT Win31 (that's Win95)
- ❌ Any neon colors → NOT Win31 (that's vaporwave)
- ❌ Any rounded corners → NOT Win31
- ❌ Any blur effects → NOT Win31
- ❌ Animated assistant character → NOT Win31 (that's Clippy/Win95)

It should have:
- ✅ Solid navy (#000080) title bar
- ✅ Single window control button
- ✅ Program Manager navigation
- ✅ System gray (#c0c0c0) base
- ✅ Beveled borders (white TL, black BR)
- ✅ Sharp corners everywhere
- ✅ Pixel fonts (VT323, Press Start 2P)
- ✅ Hard-edge box shadows only
- ✅ Cue Cards for help (not characters)

---

## File Naming Conventions

For authentic Win31 feel:
- All caps: `README.TXT`, `INSTALL.EXE`
- 8.3 format: `PROGRAM.EXE`, `CONFIG.SYS`
- Extensions matter: `.WRI`, `.BMP`, `.INI`
