<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

box-sizing: border-box;
}
html, body {

}
.wrap {
display: flex;
flex-direction: column;
height: 100%;
}
header {
height: 50px;
line-height: 50px;
text-align: center;
background-color: #ccc;
border-bottom: 1px solid #999;
}
footer {
height: 50px;
line-height: 50px;
text-align: center;
background-color: #ccc;
border-top: 1px solid #999;
}
.main {
flex: 1;
position: relative;
}
.panel {
position: absolute;
width: 100%;
height: 100%;
background-color: #ccc;
