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:
