# Slide Layouts Guide

## Overview
Layout patterns and best practices for different slide types.

## Layout Principles

### Visual Hierarchy
1. **Primary**: Title/headline (largest, boldest)
2. **Secondary**: Key points (medium, clear)
3. **Tertiary**: Supporting details (smaller, lighter)
4. **Quaternary**: Metadata (smallest, subtle)

### Balance & Alignment
- **Rule of thirds**: Divide slide into 9 sections
- **White space**: 30-40% minimum
- **Alignment grid**: Consistent margins and gutters
- **Visual weight**: Balance text, images, and data

## Responsive Layouts

### Mobile-First Considerations

- Single column layouts
- Touch-friendly spacing
- Simplified graphics

### Aspect Ratios
- **16:9** (Standard): 1920×1080px
- **4:3** (Traditional): 1024×768px
- **16:10** (Modern): 1920×1200px
- **1:1** (Social): 1080×1080px

## Color Usage

### Background Options
1. **White**: Maximum readability
2. **Light gray**: Reduces glare
3. **Dark**: For high contrast
4. **Gradient**: Adds depth
5. **Pattern**: Subtle texture

### Text Colors
- **Primary text**: High contrast (90%+)
- **Secondary text**: Medium contrast (70%+)
- **Accent text**: Brand color
- **Disabled text**: Low contrast (40%)

## Typography Guidelines

### Font Pairing
```
Heading Font + Body Font
- Inter + Noto Sans KR (OurDigital primary)
- Arial + Georgia
- Helvetica + Times
- Roboto + Merriweather
```

### Size Hierarchy
```
Title:        44-48pt
Subtitle:     32-36pt
Heading:      28-32pt
Subheading:   20-24pt
Body:         16-20pt
Caption:      12-14pt
```

### Line Spacing
- Titles: 1.0-1.2x
- Body text: 1.5-1.6x
- Bullets: 1.4-1.5x
- Captions: 1.2-1.3x

## Animation & Transitions

### Entrance Animations
- **Fade in**: Universal, professional
- **Slide in**: Directional emphasis
- **Grow**: Importance emphasis
- **Appear**: Simple, no distraction

### Transition Timing
- Fast: 0.3s (between related slides)
- Medium: 0.5s (section transitions)
- Slow: 1.0s (major transitions)

### Build Sequences
1. Title appears
2. Main content fades in
3. Supporting elements slide in
4. Call-to-action grows

## Accessibility Considerations

### Color Contrast
- WCAG AA: 4.5:1 for normal text
- WCAG AA: 3:1 for large text
- WCAG AAA: 7:1 for normal text

### Font Sizes
- Minimum: 14pt for body text
