水平导航菜单

使用display: inline-block或flexbox创建水平菜单。设置背景色、间距和悬停效果增强交互性。

<style>
.nav-menu {
  background-color: #333;
  padding: 0;
  list-style: none;
  display: flex;
}
.nav-menu li {
  padding: 15px 20px;
}
.nav-menu a {
  color: white;
  text-decoration: none;
}
.nav-menu li:hover {
  background-color: #111;
}
</style>

<ul class="nav-menu">
  <li><a href="#">首页</a></li>
  <li><a href="#">产品</a></li>
  <li><a href="#">服务</a></li>
</ul>

垂直下拉菜单

通过:hover伪类触发下拉效果。绝对定位实现二级菜单的层叠布局，transition添加平滑动画。

<style>
.dropdown {
  position: relative;
  display: inline-block;
}
.dropbtn {
  background-color: #4CAF50;
  padding: 12px;
  border: none;
  cursor: pointer;
}
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px rgba(0,0,0,0.2);
}
.dropdown:hover .dropdown-content {
  display: block;
}
</style>

<div class="dropdown">
  <button class="dropbtn">下拉菜单</button>
  <div class="dropdown-content">
    <a href="#">选项1</a>
    <a href="#">选项2</a>
  </div>
</div>

响应式汉堡菜单

媒体查询检测屏幕宽度，transform属性创建动画图标。JavaScript控制移动端的菜单展开/折叠。

<style>
.topnav {
  overflow: hidden;
  background-color: #333;
}
.topnav a {
  float: left;
  display: block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}
.icon {
  display: none;
}
@media screen and (max-width: 600px) {
  .topnav a:not(:first-child) {display: none;}
  .topnav a.icon {
    float: right;
    display: block;
  }
  .topnav.responsive {position: relative;}
  .topnav.responsive .icon {
    position: absolute;
    right: 0;
    top: 0;
  }
  .topnav.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
}
</style>

<div class="topnav" id="myTopnav">
  <a href="#">首页</a>
  <a href="#">产品</a>
  <a href="javascript:void(0);" class="icon" onclick="toggleMenu()">☰</a>
</div>

<script>
function toggleMenu() {
  const nav = document.getElementById("myTopnav");
  nav.classList.toggle("responsive");
}
</script>

圆角标签式菜单

border-radius实现圆角外观，box-shadow添加深度效果。活动标签使用不同背景色突出显示。

<style>
.tab-menu {
  border-radius: 10px;
  overflow: hidden;
  box-shadow: 0 2px 5px rgba(0,0,0,0.1);
}
.tab-menu a {
  float: left;
  padding: 12px 20px;
  background: #f1f1f1;
  color: #333;
  text-decoration: none;
}
.tab-menu a.active {
  background: #4CAF50;
  color: white;
}
</style>

<div class="tab-menu">
  <a class="active" href="#">标签1</a>
  <a href="#">标签2</a>
  <a href="#">标签3</a>
</div>

粘性固定菜单

position: sticky保持菜单在滚动时可见。z-index确保菜单始终位于其他内容上方。
