背景
此主题7b2的作者现在在维护新的项目，主题已经很久不更新了，而且此主题出现的时间比较早，因此夜间模式这个功能也是没有的，所以只能自己加了
我在网上找了很多相关教程，但是都不尽人意，大部分不仅部署麻烦而且部署成功后也会有很多地方被遗漏，也就是有不少地方还是白色的模块，下面是我自己整理与修复的，并且本站也在用的夜间模式相关的代码。
增加夜间模式
增加夜间模式很简单的，就是css代码量太多了和重新写一个差不多了，其实重新写一个都比后来再增加的强，因为主题又不少模块不知道是干啥用的，而且也没有文档查看，怪麻烦的。
以下是网上公开的夜间模式代码，我自己也修复了一部分，将这个代码放入文件夹里
文件路径/wp-content/themes/b2child（b2child是子主题，最好是放在子主题里）
文件名：functions.php
放入以下代码（包含白天和夜间模式的切换按钮）
// ========== 夜间模式终极修正版（统一使用 body.night） ==========
// 1. PHP 端：根据 Cookie 或服务器时间自动给 <body> 添加 night 类（无痕浏览器完美适配）
function child_add_night_body_class($classes) {
// 优先检查 Cookie（手动切换优先）
if (isset($_COOKIE['night']) && $_COOKIE['night'] === '1') {
$classes[] = 'night';
} else if (isset($_COOKIE['night']) && $_COOKIE['night'] === '0') {
// Cookie 为 0 表示强制日间，不做任何事
} else {
// 没有 Cookie 时，用服务器时间判断（19:00-06:00）
$hour = current_time('H'); // 获取 WordPress 时区的当前小时（0-23）
if ($hour >= 19 || $hour < 6) {
$classes[] = 'night';
}
}
return $classes;
}
add_filter('body_class', 'child_add_night_body_class');
// ===== 极致防闪烁：使用 JS 在页面渲染前强制背景色（最高优先级） =====
function night_mode_force_body_bg() {
if (isset($_COOKIE['night']) && $_COOKIE['night'] === '1') {
echo '<style>body { background-color: #1a1a1a !important; }</style>';
}
}
add_action('wp_head', 'night_mode_force_body_bg', 0);
// 2. 头部输出基础内联样式 + 防闪烁脚本（优先执行）
function night_mode_head_inline() {
?>
<style id="night-mode-inline-style">

光有这些代码还不够，还有不少地方颜色还是白色的呢
补充部分
黑夜模式js补充这段代码我是放在WPCode的Site Wide Footer里的
// ===== 专门针对 B2 主题选中按钮的强力修复 =====
(function() {
// 核心函数：强制把 .picked 按钮的文字变成白色
function fixButtonText() {
// 1. 找到所有带有 picked 类的按钮
document.querySelectorAll('button.picked').forEach(function(btn) {
// 2. 用 JS 直接修改内联样式（优先级最高）
btn.style.setProperty('color', '#ffffff', 'important');
// 3. 如果按钮里有 span 包裹文字，也一起强制变白
btn.querySelectorAll('span').forEach(function(span) {
span.style.setProperty('color', '#ffffff', 'important');
});
});
}
// 4. 页面加载完成后立即执行一次
if (document.readyState === 'complete') {
fixButtonText();
} else {
document.addEventListener('DOMContentLoaded', fixButtonText);
}
// 5. B2 是 Vue 渲染，会动态替换 HTML。每 500 毫秒检查一次，防止被 Vue 恢复
setInterval(fixButtonText, 500);
})();
补充的css这段代码我是放在WPCode里的Site Wide Header
这个地方花了我好多的时间所以不公开了
以上代码放在对应位置即可获得和我这个博客一样的夜间模式的效果了
