Tailwind Configuration

Tailwind配置

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: "var(--primary)",
        secondary: "var(--secondary)",
        accent: "var(--accent)",

Dark Mode Implementation

暗色模式实现

React Context Approach

React Context方案

tsx

// ThemeProvider.tsx
const ThemeContext = createContext<{
  theme: "light" | "dark";
  toggle: () => void;
}>({ theme: "light", toggle: () => {} });

export function ThemeProvider({ children }: { children: ReactNode }) {
  const [theme, setTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    document.documentElement.dataset.theme = theme;
  }, [theme]);

  return (
    <ThemeContext.Provider
      value={{
        theme,
        toggle: () => setTheme((t) => (t === "light" ? "dark" : "light")),
      }}
    >
      {children}
    </ThemeContext.Provider>
  );
}

tsx

// ThemeProvider.tsx
const ThemeContext = createContext<{
  theme: "light" | "dark";
  toggle: () => void;
}>({ theme: "light", toggle: () => {} });

export function ThemeProvider({ children }: { children: ReactNode }) {
  const [theme, setTheme] = useState<"light" | "dark">("light");

  useEffect(() => {
    document.documentElement.dataset.theme = theme;
  }, [theme]);

  return (
    <ThemeContext.Provider
      value={{
        theme,
        toggle: () => setTheme((t) => (t === "light" ? "dark" : "light")),
      }}
    >
      {children}
    </ThemeContext.Provider>
  );
}

System Preference Detection

系统偏好检测

tsx

useEffect(() => {
  const prefersDark = window.matchMedia("(prefers-color-scheme: dark)");
  setTheme(prefersDark.matches ? "dark" : "light");

  prefersDark.addEventListener("change", (e) =>
    setTheme(e.matches ? "dark" : "light"),
  );
}, []);

tsx

useEffect(() => {
  const prefersDark = window.matchMedia("(prefers-color-scheme: dark)");
  setTheme(prefersDark.matches ? "dark" : "light");

  prefersDark.addEventListener("change", (e) =>
    setTheme(e.matches ? "dark" : "light"),
  );
}, []);

Accessibility in React

React中的无障碍设计

Focus States (Tailwind)

焦点状态（Tailwind）

css

*:focus-visible {
  @apply outline-2 outline-primary outline-offset-2;
}

css

*:focus-visible {
  @apply outline-2 outline-primary outline-offset-2;
}

Skip Link

跳转链接

tsx

<a
  href="#main"
  className="sr-only focus:not-sr-only focus:absolute
  focus:top-4 focus:left-4 focus:z-50 focus:px-4 focus:py-2
  focus:bg-primary focus:text-white focus:rounded"
>
  Skip to content
</a>

tsx

<a
  href="#main"
  className="sr-only focus:not-sr-only focus:absolute
  focus:top-4 focus:left-4 focus:z-50 focus:px-4 focus:py-2
  focus:bg-primary focus:text-white focus:rounded"
>
  Skip to content
</a>
