### Size Directive (Marp Core)

```markdown

```

- `4:3` (960x720)
- `A4` (210mm x 297mm)

### Page-Specific Directives

To change settings per slide, use `<!-- directive_name: value -->` format:

```markdown
<!-- _class: lead -->
<!-- _backgroundColor: black -->
<!-- _color: white -->

# Apply only to this slide
```

**Meaning of underscore `_`**:
- Without `_`: Apply to all following slides
- With `_`: Apply to current slide only

## Slide Breaks

```markdown
---

# First Slide

---

# Next Slide

---
```

`---` (horizontal rule) switches to a new slide.

## Headers and Footers

### Global Settings

```markdown
---
header: 'Lecture Name'
footer: 'October 2024'

```

### Per-Slide Settings

```markdown
<!-- header: 'Section 1' -->

## Pagination (Page Numbers)

```markdown
---
paginate: true
