<header>
  <nav class="main-nav">
    <div class="logo">
      <a href="#">网站名称</a>
    </div>
    <ul class="nav-links">
      <li><a href="#home">首页</a></li>
      <li><a href="#services">服务</a></li>
      <li class="dropdown">
        <a href="#products">产品</a>

          <li><a href="#web">网站开发</a></li>
          <li><a href="#mobile">移动应用</a></li>
        </ul>
      </li>
      <li><a href="#blog">博客</a></li>
      <li><a href="#contact">联系我们</a></li>
    </ul>
    <div class="search-box">
      <input type="text" placeholder="搜索...">
      <button><i class="search-icon"></i></button>
    </div>
    <div class="mobile-menu-btn">
      <span></span>
      <span></span>
      <span></span>
    </div>
  </nav>
</header>

响应式设计实现

创建适应各种设备的导航栏：

/* 基础样式 */
nav {
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 1rem 5%;
  background: #fff;
  box-shadow: 0 2px 10px rgba(0,0,0,0.1);
}
.nav-links {
  display: flex;
  gap: 1.5rem;
}
/* 下拉菜单 */
.dropdown {
  position: relative;
}
.dropdown-menu {
  position: absolute;
  top: 100%;
  left: 0;
  background: white;
  box-shadow: 0 5px 15px rgba(0,0,0,0.1);
  opacity: 0;
  visibility: hidden;
  transform: translateY(10px);
  transition: all 0.3s ease;
}
.dropdown:hover .dropdown-menu {
  opacity: 1;
  visibility: visible;
  transform: translateY(0);
}
/* 移动端适配 */
@media (max-width: 768px) {
  .nav-links {
    position: fixed;
    top: 70px;
    left: 0;
    right: 0;
    bottom: 0;
    background: white;
    flex-direction: column;
    align-items: center;
    padding-top: 2rem;
    gap: 2rem;
    clip-path: circle(0px at top right);
    transition: clip-path 0.9s ease-in-out;
  }
  .nav-active {
    clip-path: circle(150% at top right);
  }
  .mobile-menu-btn {
    display: block;
    cursor: pointer;
  }
}

增强用户体验

添加交互动画和视觉反馈：

// 移动菜单切换
const menuBtn = document.querySelector('.mobile-menu-btn');
const navLinks = document.querySelector('.nav-links');
menuBtn.addEventListener('click', () => {
  navLinks.classList.toggle('nav-active');
});
// 滚动效果
window.addEventListener('scroll', () => {
  const nav = document.querySelector('nav');
  nav.classList.toggle('scrolled', window.scrollY > 50);
});
/* 滚动效果 */
.scrolled {
  background: rgba(255, 255, 255, 0.95) !important;
  backdrop-filter: blur(10px);
  box-shadow: 0 2px 20px rgba(0,0,0,0.1);
  padding: 0.5rem 5% !important;
}
/* 链接悬停效果 */
.nav-links a {
  position: relative;
  padding: 5px 0;
}
.nav-links a::after {
  content: '';
  position: absolute;
  bottom: 0;
  left: 0;
  width: 0;
  height: 2px;
  background: #3498db;
  transition: width 0.3s ease;
}
.nav-links a:hover::after {
  width: 100%;
}

SEO与可访问性优化

创建对搜索引擎和辅助技术友好的导航栏：

<nav aria-label="主导航">
  <ul role="menubar">
    <li role="none">
      <a href="#home" role="menuitem" aria-current="page">首页</a>
    </li>
    <li role="none">
      <a href="#services" role="menuitem">服务</a>
    </li>
    <!-- 其他菜单项 -->
  </ul>
</nav>

最佳实践：

  1. 使用语义化HTML5标签
  2. 为导航添加ARIA属性
  3. 提供键盘导航支持
  4. 添加skip navigation链接
  5. 确保足够颜色对比度
  6. 使用有意义的链接文本
