有一些技巧.
总体思想:
三大块
pg-header---需要固定 (height:48px)
pg-content
menu 右侧菜单-需要固定(width:200px; top:48;left:0; bottom:0;)
content---当内容较多时候需要有滚动条(top:48;left:200px;right:0; bottom:0; overflow: auto;)pg-footer
关键技术:
position绝对定位
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>后台管理</title>
<style>
.fl {
float: left;
}
.fr {
float: right;
}
body {
margin: 0;
}
.pg-header {
margin: 0 auto;
height: 48px;
background-color: black;
}
.pg-content .menu {
width: 200px;
position: fixed;
top: 48px;
left: 0;
bottom: 0;
background-color: bisque;
}
.pg-content .content {
position:
fixed
