css网站制作实例

响应式导航栏制作

使用Flexbox布局实现自适应导航栏，兼容不同屏幕尺寸。代码示例：

.navbar {
  display: flex;
  justify-content: space-between;
  padding: 1rem;
  background-color: #333;
}
.nav-item {
  color: white;
  padding: 0.5rem 1rem;
}
@media (max-width: 768px) {
  .navbar { flex-direction: column; }
}

卡片悬停动画效果

通过CSS过渡实现卡片悬停放大与阴影效果：

.card {
  transition: transform 0.3s, box-shadow 0.3s;
  box-shadow: 0 2px 5px rgba(0,0,0,0.1);
}
.card:hover {
  transform: scale(1.05);
  box-shadow: 0 5px 15px rgba(0,0,0,0.2);
}

渐变按钮设计

创建带有颜色渐变和悬停效果的按钮：

.btn-gradient {
  background: linear-gradient(45deg, #FF8A00, #E52E71);
  border: none;
  color: white;
  padding: 12px 24px;
  border-radius: 25px;
  cursor: pointer;
  transition: opacity 0.3s;
}
.btn-gradient:hover {
  opacity: 0.9;
}

网格布局系统

使用CSS Grid创建三栏布局模板：

.grid-container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 20px;
  padding: 20px;
}
.grid-item {
  background: #f5f5f5;
  padding: 15px;
  border-radius: 8px;
}
@media (max-width: 992px) {
  .grid-container { grid-template-columns: repeat(2, 1fr); }
}

自定义复选框样式

替换默认复选框的视觉样式：

.custom-checkbox {
  position: relative;
  width: 20px;
  height: 20px;
  -webkit-appearance: none;
  background: #eee;
  border-radius: 4px;
}
.custom-checkbox:checked {
  background: #2196F3;
}
.custom-checkbox:checked::after {
  content: "✓";
  position: absolute;
  color: white;
  left: 4px;
  top: 0;
}

视差滚动效果

通过background-attachment实现视差滚动：

.parallax-section {
  height: 500px;
  background-image: url('bg.jpg');
  background-attachment: fixed;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}

文字描边效果

为标题添加文字描边增强视觉冲击力：

.text-outline {
  color: white;
  text-shadow: 
    -1px -1px 0 #000,
    1px -1px 0 #000,
    -1px 1px 0 #000,
    1px 1px 0 #000;
  font-size: 3rem;
}

加载动画实现

创建旋转加载指示器：

@keyframes spin {
  from { transform: rotate(0deg); }
  to { transform: rotate(360deg); }
}
.loader {
  width: 40px;
  height: 40px;
  border: 4px solid rgba(0,0,0,0.1);
  border-radius: 50%;
  border-top-color: #3498db;
  animation: spin 1s linear infinite;
}
