如何将现有代码适配iPhone 14 Pro实现右侧汉堡下拉菜单？

前提假设 #

先假定你的HTML结构如下（需配合此CSS使用）：

<header class="mobile-header">
  <a href="#" class="logo">Your Logo</a>
  <!-- 用原生checkbox实现无JS基础交互 -->
  <input type="checkbox" id="hamburger-toggle" class="hamburger-toggle">
  <label for="hamburger-toggle" class="hamburger-btn" aria-label="Toggle navigation menu">
    <span class="hamburger-line"></span>
    <span class="hamburger-line"></span>
    <span class="hamburger-line"></span>
  </label>
  <nav class="mobile-menu">
    <a href="#" class="menu-logo">Your Logo</a>
    <a href="#" class="menu-item">Home</a>
    <a href="#" class="menu-item">About Us</a>
    <a href="#" class="menu-item">Gallery</a>
    <a href="#" class="menu-item">Contact</a>
    <a href="#" class="menu-action-btn">Contact Us</a>
  </nav>
</header>

关键说明 #

• 依赖原生checkbox状态实现无JS的展开/收起交互，兼容性拉满
• 针对iPhone 14 Pro的393px宽度做了细节优化，匹配设备显示效果
• 汉堡按钮带有平滑旋转动画，提升交互质感
• 菜单展开后全屏覆盖，符合移动端导航的常规设计逻辑
