<div class="topnav"> <a class="active" href="#home">主页</a> <a href="#about">关于</a> <a href="#contact">联系我们</a> <input type="text" placeholder="搜索.."> </div>
/* 在顶部导航栏中添加黑色背景颜色 */
.topnav {
overflow: hidden;
background-color: #e9e9e9;
}
/* 设置导航栏的链接样式 */
.topnav a {
float: left;
display: block;
color: black;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
/* 在悬停时更改链接的颜色 */
.topnav a:hover {
background-color: #ddd;
color: black;
}
/* 突出显示当前选中的元素 */
.topnav a.active {
background-color: #2196F3;
color: white;
}

.topnav input[type=text] {
float: right;
padding: 6px;
border: none;
margin-top: 8px;
margin-right: 16px;
font-size: 17px;
}
/* 当屏幕宽度小于 600px 时，垂直堆叠显示菜单选项和搜索框 */
@media screen and (max-width: 600px) {
.topnav a, .topnav input[type=text] {
float: none;
display: block;
text-align: left;
width: 100%;
