Blockquote Syntax

Blockquotes are used to highlight quoted text or emphasize important information. In Markdown, use the > symbol to create blockquote blocks.

Basic Blockquote Syntax

Single-line Blockquote

Use the > symbol at the beginning of a line to create a blockquote:

> This is a blockquote.

Rendered Output:

This is a blockquote.

Multi-line Blockquote

> This is the first line of the quote.
> This is the second line of the quote.
> This is the third line of the quote.

Rendered Output:

This is the first line of the quote. This is the second line of the quote. This is the third line of the quote.

Paragraphs in Blockquotes

Include multiple paragraphs in a blockquote:

> This is the first paragraph of the quote.
>
> This is the second paragraph of the quote.

Rendered Output:

This is the first paragraph of the quote.

Nested Blockquotes

Basic Nesting

Use >> to create nested blockquotes:

> This is the first level quote.
>
> > This is the second level quote.
>
> Back to the first level quote.

Rendered Output:

This is the first level quote.

This is the second level quote.

Back to the first level quote.

Multi-level Nesting

> Level 1 quote
> > Level 2 quote
> > > Level 3 quote
> > > > Level 4 quote
> >
> > Back to level 2
>
> Back to level 1

Rendered Output:

Common Errors and Solutions

1. Missing > Symbol

❌ Incorrect:
> First line of quote
Second line missing > symbol  ← This line will not be included in the quote

✅ Correct:
> First line of quote
> Second line correctly quoted

2. Nesting Level Error

❌ Incorrect:
> Level 1
> > > Jumped directly to level 3  ← Skipped level 2

✅ Correct:
> Level 1
> > Level 2
> > > Level 3

3. Blank Line Handling

❌ Potential issue:
> First paragraph

> Second paragraph  ← This creates two separate blockquotes

✅ Correct multi-paragraph quote:
> First paragraph
>
> Second paragraph

Best Practices

1. Keep Style Consistent

✅ Recommended: Unified blockquote style
> All important information uses blockquotes
> Keep formatting consistent

❌ Not recommended: Mixed usage
> Sometimes use blockquote
**Sometimes use bold instead**

2. Use Nesting Appropriately

✅ Recommended: Simple and clear nesting
> Main point
> > Supporting argument
> 
> Continue main point

❌ Not recommended: Too deep nesting
> > > > > Too deep, hard to read

3. Use Semantically

✅ Recommended: Meaningful blockquotes
> This is important information from an authoritative document

❌ Not recommended: Decorative blockquotes
> This is just normal text, no need for blockquote formatting

HTML Output

Markdown blockquotes are converted to HTML:

> This is quoted text

Becomes:

<blockquote>
  <p>This is quoted text</p>
</blockquote>

Nested blockquotes:

> Level 1
> > Level 2

Becomes:

<blockquote>
  <p>Level 1</p>
  <blockquote>
    <p>Level 2</p>
  </blockquote>
</blockquote>

Custom Styles

Some Markdown processors support custom blockquote styles:

GitHub-style Admonitions

> [!NOTE]
> This is an info note

> [!WARNING]
> This is a warning note

> [!IMPORTANT]
> This is an important note

Using HTML and CSS

<blockquote style="border-left: 4px solid #3498db; padding-left: 1em; color: #7f8c8d;">
This is a custom styled blockquote
</blockquote>

Practical Examples

Example in API Documentation

## User Authentication

User authentication is a necessary step to access the API.

> **Authentication Method**
> 
> Our API uses Bearer Token for authentication:
> 
> ```bash
> curl -H "Authorization: Bearer YOUR_TOKEN" \
>      https://api.example.com/users
> ```

### Request Example

Send a POST request to create a user:

> ```json
> {
>   "name": "John Doe",
>   "email": "john@example.com",
>   "role": "user"
> }
> ```
