菜单制作 css

使用 CSS 创建菜单

CSS 可以用于创建各种类型的菜单，包括水平菜单、垂直菜单、下拉菜单等。以下是一些常见的菜单制作方法：

水平菜单

<ul class="horizontal-menu">
  <li><a href="#">首页</a></li>
  <li><a href="#">产品</a></li>
  <li><a href="#">服务</a></li>
  <li><a href="#">关于我们</a></li>
</ul>

.horizontal-menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #333;
}

.horizontal-menu li {
  float: left;
}

.horizontal-menu li a {
  display: block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.horizontal-menu li a:hover {
  background-color: #111;
}

垂直菜单

<ul class="vertical-menu">
  <li><a href="#">首页</a></li>
  <li><a href="#">产品</a></li>
  <li><a href="#">服务</a></li>
  <li><a href="#">关于我们</a></li>
</ul>

.vertical-menu {
  list-style-type: none;
  margin: 0;
  padding: 0;
  width: 200px;
  background-color: #f1f1f1;
}

.vertical-menu li a {
  display: block;
  color: #000;
  padding: 8px 16px;
  text-decoration: none;
}

.vertical-menu li a:hover {
  background-color: #555;
  color: white;
}

下拉菜单

<div class="dropdown">
  <button class="dropbtn">下拉菜单</button>
  <div class="dropdown-content">
    <a href="#">链接 1</a>
    <a href="#">链接 2</a>
    <a href="#">链接 3</a>
  </div>
</div>

.dropdown {
  position: relative;
  display: inline-block;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;
}

.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown-content a:hover {background-color: #f1f1f1}

.dropdown:hover .dropdown-content {
  display: block;
}

响应式菜单

对于移动设备友好的响应式菜单：

<div class="topnav" id="myTopnav">
  <a href="#home" class="active">首页</a>
  <a href="#news">新闻</a>
  <a href="#contact">联系我们</a>
  <a href="#about">关于</a>
  <a href="javascript:void(0);" class="icon" onclick="myFunction()">
    ☰
  </a>
</div>

.topnav {
  overflow: hidden;
  background-color: #333;
}

.topnav a {
  float: left;
  display: block;
  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

.topnav a:hover {
  background-color: #ddd;
  color: black;
}

.topnav a.active {
  background-color: #4CAF50;
  color: white;
}

.topnav .icon {
  display: none;
}

@media screen and (max-width: 600px) {
  .topnav a:not(:first-child) {display: none;}
  .topnav a.icon {
    float: right;
    display: block;
  }
}

@media screen and (max-width: 600px) {
  .topnav.responsive {position: relative;}
  .topnav.responsive .icon {
    position: absolute;
    right: 0;
    top: 0;
  }
  .topnav.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
}

function myFunction() {
  var x = document.getElementById("myTopnav");
  if (x.className === "topnav") {
    x.className += " responsive";
  } else {
    x.className = "topnav";
  }
}

固定导航菜单

.navbar {
  position: fixed;
  top: 0;
  width: 100%;
}

.content {
  margin-top: 60px;
}

带图标的菜单

<ul class="icon-menu">
  <li><a href="#"><i class="fa fa-home"></i> 首页</a></li>
  <li><a href="#"><i class="fa fa-search"></i> 搜索</a></li>
</ul>

.icon-menu li a {
  padding-left: 40px;
  position: relative;
}

.icon-menu li a i {
  position: absolute;
  left: 15px;
  top: 50%;
  transform: translateY(-50%);
}

这些示例展示了如何使用纯CSS创建各种类型的菜单。可以根据需要调整颜色、大小和布局以满足特定设计需求。
