+title: "代码高亮"
+weight: 3
+---
+
+Hugo 使用 [Chroma](https://github.com/alecthomas/chroma)，一种纯 Golang 实现的代码高亮渲染器.
+建议对 Markdown 内容中的代码块使用反引号. 例如: 
+
+<!--more-->
+
+````markdown {filename="Markdown"}
+```python
+def say_hello():
+    print("Hello!")
+```
+````
+
+将呈现为：
+
+```python
+def say_hello():
+    print("Hello!")
+```
+
+## 特性
+
+### 文件名
+
+要向代码块添加文件名或标题, 请设置 `filename`:
+
+````markdown {filename="Markdown"}
+```python {filename="hello.py"}
+def say_hello():
+    print("Hello!")
+```
+````
+
+```python {filename="hello.py"}
+def say_hello():
+    print("Hello!")
+```
+
+### 行号
+
+如需设置行号, 将 `linenos` 设置为 `table` , 并将 `linenostart` 设置为起始行号:
+
+````markdown {filename="Markdown"}
+```python {linenos=table,linenostart=42}
+def say_hello():
+    print("Hello!")
+```
+````
+
+```python {linenos=table,linenostart=42}
+def say_hello():
+    print("Hello!")
+```
+
+### 突出显示线条
+
+要突出显示线条, 设置 `hl_lines` 为行号:
+
+````markdown {filename="Markdown"}
+```python {linenos=table,hl_lines=[2,4],linenostart=1,filename="hello.py"}
+def say_hello():
+    print("Hello!")
+
+def main():
+    say_hello()
+```
+````
+
+```python {linenos=table,hl_lines=[2,4],linenostart=1,filename="hello.py"}
+def say_hello():
+    print("Hello!")
+
+def main():
+    say_hello()
+```
+
+
+### 复制按钮
+
+默认情况下, 为代码块启用复制按钮.
+
+
+## 支持的语言
