Introduction
Creating visually appealing and effective presentations is crucial for conveying information clearly and engaging your audience. In the realm of digital content creation, Markdown has emerged as a lightweight and intuitive markup language for formatting text. Its simplicity allows writers to focus on content rather than complex formatting rules. Marp (Markdown Presentation Ecosystem) leverages this power, enabling you to create beautiful, professional-looking presentations using nothing more than a text editor and your familiar Markdown syntax.
Gone are the days of wrestling with bulky presentation software, navigating intricate menus, and constantly adjusting layouts. With Marp, your presentation is simply a Markdown file, making it easy to version control, collaborate on, and generate into various formats like HTML, PDF, and PowerPoint.
While many tools exist, Marp offers a unique blend of simplicity, power, and elegance for generating stunning slideshows directly from Markdown. This tutorial will guide you through the process of using Marp, from setup to creating your first dynamic presentation.

Marp isn't just another presentation tool; it's a paradigm shift in how you approach slide creation. Here's why it stands out:
- Simplicity and Speed: If you're comfortable with Markdown, you're already halfway there. Creating slides is as simple as writing headings and paragraphs. This drastically speeds up the presentation creation process.

- Cross-Platform Compatibility: Marp is a command-line tool and VS Code extension, making it accessible on Windows, macOS, and Linux. The generated output (HTML, PDF, PPTX) is universally viewable.
- Developer-Friendly: For developers, Marp's integration with Markdown and its extensibility make it a powerful tool for showcasing code, technical concepts, and project updates.
- Automatic Scaling and Layout: Marp intelligently handles slide scaling and basic layouts, ensuring your content looks good on various screen sizes without manual adjustments.
- Built-in Themes and Directives: Marp comes with sensible default themes and powerful directives (e.g.,
_class,_header,_footer) to control slide appearance and add dynamic elements.

Your First Marp Presentation: A Hands-On Example
Now that you have everything set up, let's create your very first Marp presentation.
Step 1: Create a New Markdown File
- In VS Code, create a new file:

Enhancing Your Marp Presentations: Advanced Tips
Marp offers several directives and features to make your presentations even more dynamic and visually appealing.
1. Global Directives
Place these at the very top of your Markdown file, between the initial ` — -` markers.
* `marp: true`: Essential to enable Marp rendering.
* `theme: default` (or `gaia`, `uncover`): Choose a built-in theme.
* `size: 16:9` (or `4:3`, `1920x1080`): Set the aspect ratio or resolution.
* `backgroundColor: lightblue`: Set a default background color for all slides.
* `backgroundImage: url('path/to/image.jpg')`: Set a default background image.
* `paginate: true`: Add page numbers to your slides.Example:
---
marp: true
theme: gaia
size: 16:9
paginate: true
backgroundColor: #f0f8ff
---
# My Themed Presentation
2. Local Directives (Per-Slide)
You can apply directives to individual slides by placing them at the beginning of the slide content, after the --- separator.
_class: lead: Apply a CSS class to a specific slide (e.g., for larger text)._backgroundColor: purple: Override the background color for a single slide._backgroundImage: url('another-image.png'): Override the background image._header: My Section: Add a header to a slide (appears on subsequent slides until changed)._footer: Confidential: Add a footer to a slide.
Example:
---
marp: true
theme: default
---
# Introduction
---
_class: lead
_backgroundColor: #ffe0b2
# Key Point
This slide has a larger font and a custom background color.
---
_header: Section 1
_footer: Page 2

3. Custom CSS Themes
For ultimate control over your presentation's appearance, you can create your own CSS themes.
- Create a CSS file, e.g.,
my_custom_theme.css. - Define your styles within this file. Marp uses specific CSS variables and selectors. Refer to Marp's official documentation for detailed theming guidelines.
- Tip: Inspect the elements of Marp's default themes (
default.css,gaia.css,uncover.cssin the Marp VS Code extension directory) to understand their structure. - In your Markdown file, specify your custom theme:
---
marp: true
theme: @my_custom_theme.css
---
# Using Custom Theme(Note: You might need to specify the full path if the CSS file is not in the same directory or configured otherwise.)
4. Inline SVG Images
Marp intelligently converts Markdown to SVG for better scaling and performance. You can also embed SVG directly into your Markdown for even more dynamic visuals.
5. Math Typesetting with KaTeX
Marp supports rendering mathematical equations using KaTeX. Enclose your LaTeX math expressions within $ for inline math and $$ for display math.
---
marp: true
---
# Math Example
Inline math: $\alpha + \beta = \gamma$
Display math:
$$
\int_a^b f(x) dx = F(b) - F(a)
$$
