代码块会一直持续，直到遇到未缩进的行（或文档结尾）。
在代码块中，**& 符号**和**尖括号（< 和 >）**会自动转为 HTML 实体。
代码：
```html
```
Preview:

下述“围栏代码块”和“语法高亮”是扩展语法，提供了另一种书写代码块的方式。
#### 围栏代码块
只需用 ` ``` ` 包裹代码（如下所示），无需再缩进四个空格。
代码：
Here's an example:
```
function test() {
console.log("notice the blank line before this function?");
}
```
Preview:
---
Here's an example:
```
function test() {
console.log("notice the blank line before this function?");
}
```
---
#### 语法高亮
在围栏代码块后加上可选的语言标识，即可实现语法高亮（[支持的语言列表](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml)）。
代码：
```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
