# Documents Deep Dive

## Structure with Styles

**Why use Styles:**
- Automatic Table of Contents
- Consistent formatting throughout
- Easy global changes (change Heading 1 once, all update)

**Hierarchy:**
- Title → document name
- Heading 1 → major sections
- Heading 2 → subsections
- Heading 3 → sub-subsections
- Normal → body text

**Modify Style:** Right-click style → Modify → Change font, spacing, color

### Page Numbers

2. Double-click footer on page 3
3. Uncheck "Link to Previous"
4. Insert Page Number → Format → Start at 1

### Different First Page
