Hugo 通过 Chroma 提供非常快速的语法高亮显示，现 Hugo 中使用 Chroma 作为代码块高亮支持，它内置在 Go 语言当中，速度是真的非常、非常快，而且最为重要的是它也兼容之前我们使用的 Pygments 方式。
|
|||
|
|
|
|||
|
|
以下通过 Hugo 内置短代码 `highlight` 和 `Markdown` 代码块方式分别验证不同语言的代码块渲染效果并能正确高亮显示，有关优化语法突出显示的更多信息，请参阅 [Hugo 文档](https://gohugo.io/getting-started/configuration-markup#highlight)。
