# Sketch Design

Master professional UI/UX design in Sketch, the vector-based design tool for macOS with powerful symbols, libraries, and plugins.

## Overview

Sketch is a vector-based design tool exclusively for macOS, focused on UI/UX design. It offers powerful symbols, shared libraries, an extensive plugin ecosystem, and efficient workflows for creating digital products.

## Core Concepts

### Vector Design

**Vector vs. Raster**:
- Scalable without quality loss
- Resolution-independent
- Smaller file sizes
- Editable shapes
- Perfect for UI design

**Vector Tools**:
- Shapes (rectangle, circle, polygon)
- Pen tool for custom paths
- Boolean operations
- Vector editing
- Path manipulation

### Artboards

**Purpose**:
- Represent screens or pages
- Organize designs
- Export individual screens
- Present flows
- Multiple device sizes

**Artboard Management**:
- Preset sizes (iPhone, iPad, Desktop)
- Custom dimensions
- Arrange in canvas
- Name descriptively
- Group related artboards

### Pages

**Organization**:
- Separate sections of project
- Symbols page
- Design pages
- Archive page
- Exploration page

**Best Practices**:
- Logical grouping
- Clear naming
- Separate final from explorations
- Archive old versions
- Keep symbols organized

## Symbols and Components

### Creating Symbols

**What Are Symbols**:
- Reusable components
- Master symbol and instances
- Update all instances globally
- Override properties
- Nested symbols

**Creating Symbols**:
1. Design element
2. Select and create symbol (Cmd+Y)
3. Name descriptively
4. Organize in Symbols page
5. Use in designs

**Symbol Overrides**:
- Text content
- Images
- Nested symbols
- Layer styles
- Maintain structure

### Nested Symbols

**Purpose**:
- Complex components
- Flexible variations
- Efficient updates
- Modular design

**Example**:
- Button symbol contains icon symbol
- Card symbol contains button symbol
- Override icon in button
- Override button in card

### Symbol Organization

**Naming Convention**:
- Use slashes for hierarchy
- Example: Button/Primary/Large
- Creates folders in symbol menu
- Easy to find and manage
- Consistent structure

**Best Practices**:
- Atomic design principles
- Clear hierarchy
- Descriptive names
- Logical grouping
- Regular cleanup

## Styles

### Text Styles

**Purpose**:
- Consistent typography
- Global updates
- Design system foundation
- Efficient workflow

**Creating Text Styles**:
1. Format text
2. Create text style
3. Name (e.g., Heading/H1)
4. Apply to other text
5. Update globally

**Text Style Properties**:
- Font family and weight
- Size and line height
- Letter spacing
- Color
- Alignment

### Layer Styles

**Purpose**:
- Reusable visual styles
- Fills, borders, shadows
- Consistent appearance
- Global updates

**Creating Layer Styles**:
1. Style layer (fill, border, shadow)
2. Create layer style
3. Name descriptively
4. Apply to other layers
5. Update globally

**Layer Style Properties**:
- Fills (color, gradient, image)
- Borders
- Shadows (inner and outer)
- Blur
- Opacity

### Color Variables

**Purpose**:
- Centralized color management
- Theme support
- Easy updates
- Consistency

**Using Color Variables**:
- Define color palette
- Name colors (Primary, Secondary, etc.)
- Use in fills, borders, text
- Update globally
- Support light/dark themes

## Layout and Alignment

### Smart Layout

**Purpose**:
- Responsive symbols
- Automatic resizing
- Maintain spacing
- Adapt to content

**How It Works**:
- Enable on symbol
- Define pinning rules
- Content adapts automatically
- Maintains relationships

**Use Cases**:
- Buttons that resize with text
- Cards with variable content
- Lists that grow
- Responsive components

### Stacks

**Purpose**:
- Automatic layout
- Spacing control
- Alignment
- Responsive design

**Stack Properties**:
- Horizontal or vertical
- Spacing between items
- Alignment
- Padding
- Resize behavior

### Grids and Guides

**Layout Grids**:
- Column grids
- Row grids
- Baseline grids
- Custom grids
- Per-artboard settings

**Guides**:
- Manual guides
- Snap to guides
- Align elements
- Consistent spacing
- Ruler guides

## Prototyping

### Creating Prototypes

**Hotspots**:
- Define clickable areas
- Link to artboards
- Set transitions
- Create user flows

**Transitions**:
- Slide from direction
- Fade
- None (instant)
- Custom duration
- Easing

### Smart Animate

**Purpose**:
- Automatic animations
- Smooth transitions
- Matches layers by name
- Position, size, opacity changes

**How to Use**:
1. Duplicate artboard
2. Modify elements
3. Keep layer names same
4. Link with Smart Animate
5. Preview animation

### Prototyping Tools
