水平导航栏

使用 display: inline-block 或 flexbox 创建水平导航栏是最常见的方法。

<nav class="horizontal-nav">
  <ul>
    <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</a></li>
  </ul>
</nav>

.horizontal-nav ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  background-color: #333;
}

.horizontal-nav li {
  display: inline-block;
}

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

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

垂直导航栏

通过设置 display: block 可以轻松创建垂直导航栏。

<nav class="vertical-nav">
  <ul>
    <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</a></li>
  </ul>
</nav>

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

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

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

响应式导航栏

使用媒体查询和 JavaScript 可以创建在小屏幕上折叠的导航栏。

<nav class="responsive-nav">
  <div class="menu-icon">☰</div>
  <ul class="nav-list">
    <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</a></li>
  </ul>
</nav>

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

.responsive-nav li {
  float: left;
}

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

.responsive-nav li a:hover {
  background-color: #111;
}

.responsive-nav .menu-icon {
  display: none;
  color: white;
  font-size: 24px;
  padding: 14px 16px;
  cursor: pointer;
}

@media screen and (max-width: 600px) {
  .responsive-nav li {float: none;}
  .responsive-nav li a {display: none;}
  .responsive-nav .menu-icon {
    display: block;
    float: right;
  }
}

下拉菜单导航

结合 CSS 伪类和定位可以创建下拉菜单效果。

<nav class="dropdown-nav">
  <ul>
    <li><a href="#">首页</a></li>
    <li class="dropdown">
      <a href="#" class="dropbtn">产品</a>
      <div class="dropdown-content">
        <a href="#">产品1</a>
        <a href="#">产品2</a>
        <a href="#">产品3</a>
      </div>
    </li>
    <li><a href="#">服务</a></li>
    <li><a href="#">关于</a></li>
  </ul>
</nav>

.dropdown-nav ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
  background-color: #333;
}

.dropdown-nav li {
  float: left;
}

.dropdown-nav li a, .dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown-nav li a:hover, .dropdown:hover .dropbtn {
  background-color: #111;
}

.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;
  text-align: left;
}

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

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