可扩展的搜索表单

标签： html css

我正在开发可扩展搜索但面临一个问题。当我点击搜索栏时，搜索栏正在扩展。但右侧内容正在向下移动。我想在搜索栏展开时隐藏右侧内容，类似于stackoverflow搜索栏。

使用您的结构，不能仅使用css。但是，如果改变结构，你可能会有类似的东西。

*{
  box-sizing: border-box;
  font-family: arial;
}

input{
  padding: 10px;
  background: #eee;
  border: 1px solid #ddd;
  display: inline-block;
  transition: .3s;
  margin-right: 10px;
  width: 250px;
}

input:focus{
  width: 400px;
}

input:focus + div{
  opacity: 0;
  visibility: hidden;
}

ul{
  padding: 0;
  margin: 0;
}

ul li{
  display: inline;
  margin-right: 5px;
}

div {
 display: inline-block;
 transition: .3s;
}
<input type="search" placeholder="Search">
<div class="ga_d">
	<ul>
		<li>Login</li>
		<li>Register</li>
	</ul>
</div>
