<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
.Site {
display: flex;
min-height: 100vh;
flex-direction: column;
}
/*相对于viewport高度大小的文字*/
/*h1{font-size:8vh;}*/
/*如果视口的高度是200mm，那么上述代码中h1元素的字号将为16mm，即(8x200)/100*/
.Site-content {
flex: 1;
}
</style>
</head>
<body>
<body class="Site">
<header>...</header>
<main class="Site-content">...</main>
<footer>...</footer>
