效果還不錯 就差加上鍵盤控制了...
代碼如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>迷糊網羅</title>
<style type="text/css">
* {
margin: 0;
padding: 0;
}
form {
position: absolute;
left: 50%;
top: 40%;
}
form input:nth-child(1) {
width: 450px;
height: 34px;
float: left;
font-size: 16px;
text-indent: 0.5em;
outline: none;
box-sizing: border-box;
}
form input:nth-child(1):focus {
border: 1px solid blueviolet;
}
form input:nth-child(2) {
height: 34px;
float: left;
background: blueviolet;
cursor: pointer;
width: 80px;
letter-spacing: 2px;
border: 0;
font-size: 14px;
line-height: 34px;
}
#oul {
position: absolute;
left: 0;
top: 34px;
background: white;

box-shadow: 3px 3px 5px #F3F3F3;
