Introduction

Markdown serves as the backbone of text formatting on competitive programming platforms like Luogu. This lightweight markup language allows users to format their solutions, blogs, and discussions with simple syntax that gets automatically converted into styled HTML.

When you encounter the prompt "希望更丰富的展现？使用 Markdown" while editing content on Luogu, you're being invited to use this powerful formatting system. This guide will walk you through everything you need to know to master Markdown on these platforms.

What is Markdown?

Markdown is a lightweight markup language designed for readability and ease of writing. In practical terms, you write plain text using special symbols (the source code), and the platform renders this into formatted HTML automatically.

Consider this simple example: typing _Hello_ (with underscores on both sides) renders as Hello in italic. The platform handles all the conversion behind the scenes.

Luogu specifically uses Markdown*Palettes (available on GitHub) as its rendering angine. Despite initially appearing intimidating, Markdown uses only a handful of special symbols—typically fewer than twenty—to achieve comprehensive formatting control.

The Markdown Editor Interface

The Luogu cloud clipboard editor consists of three primary components:

Toolbar - Contains frequently used formatting symbols. While helpful for beginners, advanced users typically write directly in the editor without relying on toolbar clicks.

Editing Area - The left panel where you input your source code. This is where the actual Markdown syntax gets written.

Preview Area - The right panel displaying the rendered output. This shows exactly how your content will appear after publication. Note that the preview area is read-only; modifications happen only in the editing area.

Understanding this three-panel layout is essential for efficient content creation. The real-time preview allows you to verify your formatting as you write.

Core Markdown Syntax

Headings

Markdown supports six levels of headings, created by prefixing text with hash symbols (#). The number of hashes determines the heading level—one hash creates a first-level heading, two hashes create a second-level heading, and so forth. A space must follow the hash symbols.

First-level headings are the largest, while sixth-level headings are the smallest. In the toolbar, these correspond to labels like H1, H2, H3, and so on.

# Heading Level One

## Heading Level Two

### Heading Level Three

#### Heading Level Four

##### Heading Level Five

###### Heading Level Six

This renders as progressively smaller headings. Important considerations:

• First and second-level headings automatically include underline separators in some contexts
• Fourth-level headings and below typically appear smaller than regular body text
• Always include a space after the hash symbols, otherwise they won't render correctly

Bold Text

To make text bold, wrap it with double asterisks on both sides. This syntax appears in the toolbar as the B button.

**This text appears in bold**

The toolbar offers a convenient alternative: select the text you want to bold, then click the B symbol. This automatically wraps your selection with the appropriate syntax.

Practical workflow:

1. Highlight the desired text
2. Click the B button in toolbar
3. The selected text becomes bold

This approach eliminates syntax erors and speeds up the writing process significantly.
