<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
.tab ul{
overflow: hidden;
margin: 0;
padding: 0;
}
.tab ul li{
box-sizing: border-box;
padding: 0;
float: left;
width: 100px;
height: 45px;
line-height: 45px;
list-style: none;
text-align: center;
border-top: 1px solid blue;
border-right: 1px solid blue;
cursor
}
.tab ul li:first-child {
border-left: 1px solid blue;
}
.tab ul li.active {
background-color: orange;
}
.tab div {
width: 500px;
height: 300px;
display: none;
text-align: center;
font-size: 30px;
line-height: 300px;
border: 1px solid blue;
border-top: 0px;
}
.tab div.current {
display: block;
}
</style>
