Marp Presentation Creation

Create professional presentation slides using Marp, which converts Markdown into beautiful HTML/CSS/PDF presentations.

Core Syntax

Basic Structure

---
marp: true
theme: default
paginate: true
---

# Title Slide

---

## Regular Slide

Content here

---

## Another Slide

More content

Key Points:

• Use --- (horizontal ruler) to separate slides
• First --- block contains YAML frontmatter with global directives
• Each subsequent --- creates a new slide
• Based on CommonMark Markdown specification

Directives

Global Directives (Apply to entire deck)

Define in YAML frontmatter at the start:

---
marp: true
theme: default          # Built-in: default, gaia, uncover
size: 16:9              # Aspect ratio (16:9, 4:3)
paginate: true          # Show page numbers
header: 'Header text'   # Deck-wide header
footer: 'Footer text'   # Deck-wide footer
style: |                # Custom CSS
  section {
    background-color: #fff;
  }
headingDivider: 2       # Auto-split at heading level
math: katex             # Math typesetting library
title: 'Presentation Title'
author: 'Author Name'
---

Local Directives (Apply to specific slides)

Use HTML comments for slide-specific settings:

<!-- _paginate: false -->
# Title Slide
(no page number on this slide)

---

<!--
_backgroundColor: #123456
_color: white
-->
## Slide with Custom Colors

Scoped vs Persistent:

• _directive (with underscore) = applies ONLY to current slide
• directive (no underscore) = applies to current and ALL subsequent slides

Common Local Directives

Directive	Purpose	Example
paginate	Show page number	<!-- paginate: true -->
header	Slide header	<!-- header: 'Section 1' -->
footer	Slide footer	<!-- footer: '' --> (reset)
class	CSS class	<!-- class: lead -->
backgroundColor	Background color	<!-- _backgroundColor: #e1f5fe -->
backgroundImage	Background image	<!-- backgroundImage: url('img.jpg') -->
color	Text color	<!-- _color: #333 -->

Built-in Themes

Marp includes three themes:

1. default - Clean, professional appearance
2. gaia - Modern design with accent colors
3. uncover - Minimalist presentation style

theme: gaia

Advanced Features

Image Syntax

![](image.jpg)                    # Regular image
![bg](background.jpg)             # Background image
![bg left](image.jpg)             # Split background (left)
![bg right:40%](image.jpg)        # Split background (right, 40% width)
![bg fit](image.jpg)              # Fit background
![bg contain](image.jpg)          # Contain background
![width:500px](image.jpg)         # Sized image
![height:300px](image.jpg)        # Height-specified image

Multiple Backgrounds

![bg](image1.jpg)
![bg](image2.jpg)
![bg](image3.jpg)

Math Typesetting

Enable with math: katex in frontmatter:

Inline math: $E = mc^2$

Block math:
$$
\int_0^\infty f(x)dx
$$

Auto-Scaling

Text automatically scales to fit slides. Force specific sizes:

<!-- _class: lead -->
# Large Centered Text

Custom Styling

Inject CSS via style directive:

---
style: |
  section {
    font-family: 'Arial', sans-serif;
  }
  h1 {
    color: #2196f3;
  }
---

Workflow

1. Create markdown file (e.g., presentation.md)
2. Add YAML frontmatter with global directives
3. Write content using --- to separate slides
4. Export to HTML, PDF, or PowerPoint using Marp CLI or VS Code extension

Best Practices

• One idea per slide: Keep slides focused
• Use headings: # for title slides, ## for content slides
• Leverage directives: Use _paginate: false on title/section slides
• Background images: Use ![bg fit] for full-screen imagery
• Split layouts: Combine ![bg left] with content on right
• Consistent styling: Define global styles in frontmatter
• Test pagination: Ensure page numbers appear where intended

Common Patterns
