css导航制作

CSS导航制作方法

固定导航栏到页面顶部

.navbar {
  position: fixed;
  top: 0;
  width: 100%;
  z-index: 1000;
  background-color: #333;
}

水平导航栏样式

.nav-list {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

.nav-item {
  float: left;
}

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

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

下拉菜单实现

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

响应式导航设计

@media screen and (max-width: 600px) {
  .nav-item {
    float: none;
    width: 100%;
  }

  .dropdown-content {
    position: static;
  }
}

添加过渡动画效果

.nav-link {
  transition: background-color 0.3s ease;
}

.dropdown-content {
  transition: opacity 0.3s ease;
}

当前活动页指示

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

粘性导航实现

.sticky {
  position: sticky;
  top: 0;
}
