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)
提及用户
@Vanessa 通过 @User 可以在内容中提及用户，被提及的用户将会收到系统通知。
NOTE:
- @用户名之后需要有一个空格
- 新手没有艾特的功能权限
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，可在个人设置中设置常用表情。
一些表情例子
😄 😆 😵 😭 😰 😅 😢 😤 😍 😌 👍 👎 💯 👏 🔔 🎁 ❓ 💣 ❤️ ☕ 🌀 🙇 💋 🙏 💢
大标题 - Heading 3
你可以选择使用 H1 至 H6，使用 ##(N) 打头。建议帖子或回帖中的顶级标题使用 Heading 3，不要使用 1 或 2，因为 1 是系统站点级，2 是帖子标题级。
NOTE: 别忘了 # 后面需要有空格！
Heading 4
Heading 5
Heading 6
图片
支持复制粘贴直接上传。
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…

表格
如果需要展示数据什么的，可以选择使用表格。
| header 1 | header 2 |
|---|---|
| cell 1 | cell 2 |
| cell 3 | cell 4 |
| cell 5 | cell 6 |

这里是摘要部分。
这里是细节部分。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。
