Tailwind 黑暗模式在没有体内黑暗类别的情况下影响

Question

我在 NextJS 中创建了一个 ThemeContext 来切换我的网站主题，它可以正常工作，并且在网站初始加载时，我的主体类名称中有“light”类，但我在类名称中使用“dark:”的元素正在应用深色主题而不是初始浅色主题...

这是我的主题按钮：

const ThemeButton = () => {
    const { theme, setTheme } = useTheme();
    
  return (
    <button
      className="text-primary dark:bg-containerDark bg-containerLight flex justify-center items-center w-12 h-12 rounded-xl"
      onClick={() => setTheme(theme === "light" ? "dark" : "light")}
    >
      {theme === "light" ? (
        <FaMoon className="w-5 h-5" />
      ) : (
        <PiSunDimFill className="w-5 h-5" />
      )}
    </button>
  );
};

export default ThemeButton;

这是“加载”上的按钮，如您所见，我有浅色类，“深色：”在按钮的类中是正确的：

如果你想看的话，这是我的 themeContext :

"use client";
import React, { createContext, useContext, useEffect, useState } from "react";

type Theme = "light" | "dark";

interface ThemeContextType {
  theme: Theme;
  setTheme: (theme: Theme) => void;
}

const ThemeContext = createContext<ThemeContextType | undefined>({
  theme: "light",
  setTheme: () => {},
});

export const useTheme = (): ThemeContextType => {
  const context = useContext(ThemeContext);
  if (!context) {
    throw new Error("useTheme must be used within a ThemeProvider");
  }
  return context;
};

export const ThemeProvider = ({ children }: { children: React.ReactNode }) => {
  const [theme, setTheme] = useState<Theme>("light");

  // Update the body class when theme changes
  useEffect(() => {
    document.body.classList.remove("light", "dark");
    document.body.classList.add(theme);
  }, [theme]);

  return (
    <ThemeContext.Provider value={{ theme, setTheme }}>
      {children}
    </ThemeContext.Provider>
  );
};

目前，似乎

dark:-

类正在通过系统的

prefers-color-scheme

而不是身体上的

dark

或

light

类来识别黑暗主题。

您可以尝试配置 tailwind 以使用

dark

和

light

类手动切换暗模式，如下所示： https://tailwindcss.com/docs/dark-mode#toggling-dark-mode-manually
