教程

这是一篇讲解如何正确使用 Markdown 的排版示例，学会这个很有必要，能让你的文章有更佳清晰的排版。

引用文本：Markdown is a text formatting syntax inspired

语法指导

普通内容

这段内容展示了在内容里面一些排版格式，比如：

• 加粗 – **加粗**
• 倾斜 – *倾斜*
• 删除线 – ~~删除线~~
• Code 标记 – `Code 标记`
• 超级链接 – [超级链接](https://ld246.com)
• username@gmail.com – [username@gmail.com](mailto:username@gmail.com)

表情符号 Emoji

支持大部分标准的表情符号，可使用输入法直接输入，也可手动输入字符格式。通过输入 : 触发自动完成。

一些表情例子

:smile: :laughing: :dizzyface: :sob: :coldsweat: :sweatsmile: :cry: :triumph: :hearteyes: :relieved::+1: :-1: :100: :clap: :bell: :gift: :question: :bomb: :heart: :coffee: :cyclone: :bow: :kiss: :pray: :anger:

标题

使用一个 # 是一级标题，两个 ## 是二级标题，以此类推，最多支持六级标题。

NOTE: 别忘了 # 后面需要有空格！

![alt 文本](http://image-path.png "图片 Title 值")

支持直接复制粘贴。

代码块

普通

*emphasize*    **strong**
_emphasize_    __strong__
var a = 1

语法高亮支持

如果在 ``` 后面跟随语言名称，可以有语法高亮的效果哦，比如：

演示 Go 代码高亮

package main

import "fmt"

func main() {
	fmt.Println("Hello, 世界")
}

演示 Java 高亮

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }

}

Tip: 语言名称支持下面这些： ruby, python, js, html, erb, css, coffee, bash, json, yml, xml ...

有序、无序、任务列表

无序列表

• Java

  • Spring

  • IoC

  • AOP

• Go

  • gofmt
  • Wide

• Node.js

  • Koa
  • Express

有序列表

1. Node.js

   1. Express
   2. Koa
   3. Sails

2. Go

   1. gofmt
   2. Wide

3. Java

   1. Latke
   2. IDEA

任务列表

• [X] 发布 Sym
• [X] 发布 Solo

表格

如果需要展示数据什么的，可以选择使用表格。

段落

空行可以将内容进行分段，便于阅读。（这是第一段）

使用空行在 Markdown 排版中相当重要。（这是第二段）

数学公式

多行公式块：

$$ \frac{1}{ \Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{ \frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} { 1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}}{1+\cdots}} } } $$

行内公式：

公式 $a^2 + b^2 = \color{red}c^2$ 是行内。

内容块

内容块相关语法是思源笔记对 Markdown 进行的扩展。

内容块引用

((20200817123136-in6y5m1 "内容块引用"))

“内容块引用”

内容块嵌入

!((20200920190726-xw7fial​ "内容块嵌入"))

内容块嵌入

在新一行的开始处输入 !(( 后将触发内容块嵌入搜索，和内容块引用一样，在搜索结果中选择需要的内容块就可以完成嵌入了，同样支持自定义 text ((20201123092030-1rqe6wr “锚文本”))。嵌入操作完成后下方将直接展现被嵌入的内容块。#内容块/嵌入#

#注意#：内容块嵌入本身也是一种内容块，这意味着我们不能在一句话中间使用内容块嵌入，只能在新行开始处进行嵌入操作。下面是一个内容块嵌入的示例：
