代码块

所有代码块均使用 Expressive Code,并在 styles/custom.css 中定义了自定义样式。

function fibonacci(n) {
if (n <= 1) return n;
return fibonacci(n - 1) + fibonacci(n - 2);
}
console.log(fibonacci(10)); // 55
def fibonacci(n: int) -> int:
if n <= 1:
return n
return fibonacci(n - 1) + fibonacci(n - 2)
print(fibonacci(10)) # 55
#!/bin/bash
for i in $(seq 1 5); do
echo "Iteration $i"
done

终端风格的代码块(使用 ```bash```sh 围栏)会呈现受 iTerm 启发的窗口边框,并带有 macOS 交通灯圆点。

Terminal
npm install @f5-sales-demo/docs-theme
npx astro build
npx astro preview
/* 边框 */
.expressive-code .frame.is-terminal {
border: 2px solid rgba(255, 255, 255, 0.15);
}
/* 带有交通灯 SVG 圆点的深色标题栏 */
.expressive-code .frame.is-terminal .header {
background: #323232 !important;
color: #ccc !important;
}
/* 深色模式终端主体 — 受 Tokyo Night 启发 */
:root:not([data-theme="light"]) .expressive-code .frame.is-terminal pre {
background: #1a1b26 !important;
}
/* 浅色模式边框覆盖 */
:root[data-theme="light"] .expressive-code .frame.is-terminal {
border-color: rgba(0, 0, 0, 0.2);
}
src/config.ts
export default {
site: "https://example.com",
title: "My Docs",
};
const name = "highlighted"; // 第 1 行高亮
const other = "normal";
const a = 1; // 第 3-5 行高亮
const b = 2;
const c = 3;
const d = "normal again";
const config = {
theme: "dark", // 插入
theme: "light", // 删除
lang: "en",
};
const oldValue = "deprecated";
const newValue = "replacement";
const unchanged = "stays";
removeThis();
addThis();

所有代码块均具有圆角和多层阴影:

.expressive-code .frame {
--header-border-radius: 0.75rem;
border-radius: 0.75rem;
overflow: hidden;
box-shadow: 0 2px 4px rgba(0,0,0,0.04), 0 8px 16px rgba(0,0,0,0.08), 0 24px 48px rgba(0,0,0,0.12);
}
/* 深色模式(默认) */
.expressive-code .frame.is-terminal {
border: 2px solid rgba(255, 255, 255, 0.15);
}
/* 浅色模式 */
:root[data-theme="light"] .expressive-code .frame.is-terminal {
border-color: rgba(0, 0, 0, 0.2);
}
  • 代码块背景色随主题自适应
  • 终端标题栏背景色为 #323232,并带有 macOS 交通灯圆点
  • 终端边框在深色模式下使用 rgba(255, 255, 255, 0.15),在浅色模式下使用 rgba(0, 0, 0, 0.2)
  • 深色模式终端主体使用 #1a1b26
  • 语法颜色在两种主题下均保持可读性
  • 行高亮具有可见的背景色调
  • 插入行显示绿色色调,删除行显示红色色调
  • 代码块具有 0.75rem 圆角半径和盒阴影
