HTML教程-HTML搜索框

HTML搜索框允许用户搜索内容。Search是<input>元素的type属性的一个值。

语法

<input type="search">

示例：以下示例使用不同的CSS代码在网页上显示不同的搜索框。

示例 1：

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>搜索框示例</title>
<style>
body {
  text-align: center;
  background-color: blue;
}
form {
  display: block;
  left: 30%;
  position: absolute;
  top: 30%;
}
input[type=search] {
  border: 5px orange;
  box-sizing: border-box;
  font-size: 1em;
  height: 2em;
  margin-left: 10vw;
  padding: .5em;
  transition: all 2s ease-in;
  width: 30vw;
  z-index: 1;
}
input[type=search]:focus {
  border: solid 3px #09f;
  outline: solid #fc0 2000px;
}
</style>
</head>
<body>
<form>
<input type="search" placeholder="Search for any site">
</form>
</body>
</html>

输出结果：

示例 2：在这个例子中，我们没有使用<input>元素的type属性的search值，而是使用CSS创建了一个文本输入框，它可以作为搜索字段使用。
