## 1. Typography
### Font Categories
| Category | Characteristics | Use For | Prompt Keywords |
|----------|-----------------|---------|-----------------|
| **Sans-serif** | Clean, modern, readable | Headlines, UI, tech | "bold sans-serif", "Helvetica style" |
| **Serif** | Traditional, elegant, trustworthy | Body text, luxury | "elegant serif", "Times style" |
| **Display** | Decorative, attention-grabbing | Headlines only | "display font", "decorative type" |
| **Script** | Handwritten, personal | Accents, signatures | "script font", "handwritten" |
| **Monospace** | Technical, code-like | Tech, data | "monospace", "code font" |
### Typography Rules
| Rule | Guideline |
|------|-----------|
| **Font limit** | Max 2 fonts per design (1 heading + 1 body) |
| **Size contrast** | Headlines 2-3x larger than body |
| **Weight contrast** | Bold headlines, regular body |
| **Line spacing** | 1.4-1.6x font size for readability |
| **Letter spacing** | Tighter for headlines, normal for body |
### Text Readability
| Background | Text Color | Contrast |
|------------|------------|----------|
| Light | Dark text | High contrast |
| Dark | Light text | High contrast |
| Busy image | Text with shadow/stroke/box | Added contrast |
| Gradient | Solid color area for text | Clear zone |
### Text Effects for Images
| Effect | When to Use | Prompt Keywords |
|--------|-------------|-----------------|
| **Drop shadow** | Text over varied backgrounds | "text with drop shadow" |
| **Outline/Stroke** | High visibility needed | "outlined text", "text with stroke" |
| **Background box** | Complex backgrounds | "text in box", "label style" |
| **Gradient text** | Modern, dynamic feel | "gradient text" |
| **3D text** | Playful, attention-grabbing | "3D text", "extruded text" |

## 2. Visual Hierarchy
### Hierarchy Levels
```
1. PRIMARY → Eye goes here first (largest, boldest, most contrast)
2. SECONDARY → Supporting information (medium size, less bold)
3. TERTIARY → Details, fine print (smallest, subtle)
```
### Creating Hierarchy
| Method | How It Works |
|--------|--------------|
| **Size** | Larger = more important |
| **Weight** | Bolder = more important |
| **Color** | Brighter/contrasting = more important |
| **Position** | Top-left, center = more attention |
| **Isolation** | White space around = more focus |
| **Depth** | Foreground = more important |
### F-Pattern vs Z-Pattern
| Pattern | Description | Use For |
|---------|-------------|---------|
| **F-Pattern** | Top → left side scan | Text-heavy, articles |
| **Z-Pattern** | Top-left → right → bottom-left → right | Minimal text, ads |
### Focal Point Techniques
| Technique | Description | Prompt Keywords |
|-----------|-------------|-----------------|
| **Contrast** | Brightest/darkest area | "high contrast focal point" |
| **Isolation** | Subject alone with space | "isolated subject", "negative space" |
| **Leading lines** | Lines point to subject | "leading lines to subject" |
| **Framing** | Elements surround subject | "natural frame", "framed subject" |
| **Blur** | Background soft, subject sharp | "shallow depth of field" |

## 3. Layout & Composition
### Grid Systems
| Grid | Structure | Best For |
|------|-----------|----------|
| **Rule of Thirds** | 3x3 grid, place at intersections | Photos, thumbnails |
| **Golden Ratio** | 1:1.618 spiral | Elegant compositions |
| **Center** | Subject in middle | Symmetry, impact |
| **Asymmetric** | Off-center balance | Dynamic, modern |
### Safe Zones
```
┌─────────────────────────────┐
│ ← 10% margin on all sides →│
│ ┌─────────────────────┐ │
│ │ │ │
│ │ SAFE ZONE │ │
│ │ (Key content) │ │
│ │ │ │
│ └─────────────────────┘ │
│ │
└─────────────────────────────┘
```
**Why safe zones matter:**
- Platform UI overlays (play buttons, duration)
- Mobile cropping
- Social media preview crops
### Balance Types
| Type | Description | Feel |
|------|-------------|------|
| **Symmetrical** | Mirror left/right | Formal, stable, traditional |
| **Asymmetrical** | Visual weight balanced | Dynamic, modern, interesting |
| **Radial** | Elements around center | Focus, energy, movement |
### White Space (Negative Space)
| Amount | Effect | Use For |
|--------|--------|---------|
| **Minimal** | Busy, energetic, overwhelming | Sales, urgency |
| **Moderate** | Balanced, professional | Most designs |
| **Generous** | Elegant, premium, calm | Luxury, minimal |

└─────────────────────┘
```
**Template 2: Before/After**

│ │
│ "7" VISUAL │
│ (big) CONTENT │
│ │
└─────────────────────┘
```
**Template 4: Question Hook**
```
┌─────────────────────┐
│ │
│ "Why does │
│ X happen?" │
│ + visual │
└─────────────────────┘
```
