Chapter 2
Advanced Markdown Slide Authoring

Push the boundaries of Markdown-driven presentations by unlocking the full suite of Marp’s slide authoring capabilities. This chapter invites you to master the nuanced, expressive, and programmatic tools Marp offers—from leveraging custom directives to embedding executable code and external content. Here, you’ll discover how to craft presentations that not only communicate complex ideas visually, but do so with efficiency, automation, and unprecedented reusability.

2.1 Extended Markdown Syntax in Marp

Marp extends the fundamental capabilities of standard Markdown by introducing a suite of syntactical enhancements that enable richer presentations and more expressive content structuring. These extensions, designed to integrate seamlessly with Markdown’s simplicity, include embedded support for diagrams, callouts, and customizable content blocks. By leveraging the Marp parsing engine’s ability to recognize and render these constructs, users can create interactive and semantically nuanced slides while maintaining a clear and portable document structure.

One of the hallmark extensions in Marp is its enhanced support for diagrams, facilitating the integration of visual elements directly within Markdown content via concise and specialized code blocks. These diagrams utilize popular syntaxes such as mermaid and plantuml, activated through fenced code blocks with specific language identifiers:

graph TD 
    A[Start] --> B{Decision} 
    B -->|Yes| C[Process 1] 
    B -->|No| D[Process 2]

Upon parsing, Marp’s engine identifies the mermaid tag and invokes the corresponding rendering subsystem to translate this textual representation into a scalable vector graphic, embedding it seamlessly within the slide content. This eliminates the requirement for external image dependencies or manual illustration, keeping the source text declarative and portable.

Maintaining consistent rendering across different output targets is a critical consideration. Marp employs an internal rendering pipeline that converts diagram definitions into SVG format during slide generation, preserving resolution independence and styling coherence. Users are encouraged to limit diagram complexity to ensure performant real-time rendering, especially in browser-based presentations.

Marp introduces callouts as a syntactic mechanism to highlight particular segments of content with configurable visual emphasis. Callouts manifest through block-level constructs that start with a specific marker, followed by an optional title or icon for semantic distinction. The canonical syntax follows the pattern:

> [!NOTE] 
> This is an informational callout. 
> It can span multiple lines.

The marker [!NOTE] signals to the Marp parser to apply a predefined styling that typically involves distinct background shading, iconography, and text coloring. This semantic clarity facilitates audience engagement and content differentiation without resorting to ad hoc formatting conventions.

Custom callout types can be constructed via CSS extensions within the Marp theme system, enabling precise control over colors, icons, and behavior to align with presentation aesthetics or branding guidelines. Moreover, callouts maintain compatibility with Markdown parsers by strictly adhering to blockquote syntax with augmented bracket notation, ensuring fallback readability outside Marp environments.

Expanding on callouts, Marp supports custom blocks to encapsulate arbitrary content with specialized rendering characteristics. This is particularly useful for incorporating interactive elements, alerts, or grouped content segments that require defined boundaries and styling.

Custom blocks are expressed by delineating a fenced code block with a specified class identifier, for example:

::: warning 
Make sure to back up your data before proceeding. 
:::

Here, the triple-colon syntax with a class name such as warning instructs the Marp engine to apply corresponding presentation styles defined in the slide theme’s stylesheet. This method leverages the principles of semantic HTML containers while preserving Markdown’s structural simplicity.

For interactivity, combining custom blocks with embedded HTML or script injection (within the security constraints of the output environment) allows the introduction of elements like collapsible sections, tabbed content, or live code demonstrations. However, such integrations are generally selective to environments that support dynamic content execution, and authors must balance functionality with usability and portability.

Marp’s parsing engine is architected to extend a standard Markdown Abstract Syntax Tree (AST) with nodes representing the aforementioned syntactical constructs. This extension involves pattern matching at the lexical and syntactic levels, enabling the parser to identify extended Markdown elements without compromising the fidelity of unmodified content.

The rendering pipeline transforms the enhanced AST into HTML enriched with CSS classes and inline SVG elements for diagrams, which are then styled through thematic CSS or JavaScript-driven enhancements for interactivity. The modular design supports plugin integration, facilitating the addition of new syntax extensions without core engine modifications.

Adopting extended syntax should consider the implications on export targets. For instance, PDF output generated through headless browser rendering typically preserves diagram and styling fidelity, whereas plain-text exports omit these enhancements gracefully. Thus, best practice advocates designing core content to remain intelligible in pure Markdown, using extensions as progressive enhancements.

Introducing Marp’s extended Markdown syntax enhances presentations with semantic richness and interactivity; however, disciplined usage ensures clear, maintainable, and portable source documents. Recommended guidelines include:

• Semantic clarity: Use callouts and custom blocks with meaningful labels (e.g., note, warning) to convey intent unambiguously.
• Incremental enhancements: Structure content so that standard Markdown presents a coherent narrative on its own, with Marp extensions layering supplementary visual or interactive elements.
