基础搜索框样式

使用HTML和CSS创建一个简单的搜索框。HTML部分包含一个<input>元素和一个<button>元素，CSS部分用于美化样式。

<div class="search-box">
  <input type="text" placeholder="搜索...">
  <button type="submit">搜索</button>
</div>

.search-box {
  display: flex;
  width: 300px;
  margin: 20px auto;
}

.search-box input {
  flex: 1;
  padding: 10px;
  border: 1px solid #ccc;
  border-radius: 4px 0 0 4px;
  outline: none;
}

.search-box button {
  padding: 10px 15px;
  background-color: #007bff;
  color: white;
  border: none;
  border-radius: 0 4px 4px 0;
  cursor: pointer;
}

.search-box button:hover {
  background-color: #0056b3;
}

带图标的搜索框

通过CSS伪元素或背景图添加搜索图标，提升视觉体验。

<div class="search-box">
  <input type="text" placeholder="搜索...">
  <button type="submit"><i class="icon">🔍</i></button>
</div>

.search-box {
  position: relative;
  width: 300px;
  margin: 20px auto;
}

.search-box input {
  width: 100%;
  padding: 10px 40px 10px 15px;
  border: 1px solid #ddd;
  border-radius: 20px;
  outline: none;
  box-shadow: 0 2px 5px rgba(0,0,0,0.1);
}

.search-box button {
  position: absolute;
  right: 10px;
  top: 50%;
  transform: translateY(-50%);
  background: none;
  border: none;
  cursor: pointer;
  color: #666;
}

动画效果搜索框

通过CSS过渡或动画实现交互效果，例如输入框展开或图标变色。

.search-box input {
  transition: all 0.3s ease;
}

.search-box input:focus {
  border-color: #007bff;
  box-shadow: 0 0 8px rgba(0,123,255,0.2);
  width: 350px;
}

.search-box button i {
  transition: color 0.3s;
}

.search-box input:focus + button i {
  color: #007bff;
}

响应式搜索框

使用媒体查询确保搜索框在不同设备上表现良好。

.search-box {
  width: 80%;
  max-width: 500px;
}

@media (max-width: 768px) {
  .search-box {
    width: 95%;
  }
}

高级样式：浮动标签

通过CSS实现标签浮动效果，增强用户体验。
