利用HTML和CSS实现的浮动布局

代码如下

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>Document</title><style>*{margin: 0;padding: 0;}.all{width: 960px;height: 1000px;margin: 0 auto;}.body_url{height: 80px;display: inline-block;margin-bottom: 10px;/* 去除换行空格距离 */font-size: 0;}.body_com{display: inline-block;text-align: center;line-height: 80px;background-color: rgb(171, 149, 149);font-size: 16px;}.logo{width: 200px;}.banner1{width: 540px;margin: 0 10px;}.banner2{width: 200px;}.menu{height: 30px;background-color: rgb(171, 149, 149);text-align: center;line-height: 30px;margin-bottom: 10px;}.nav_left{width: 760px;float: left;font-size: 0;}.left_one{display: inline-block;width: 368px;height: 198px;text-align: center;line-height: 100px;border: 1px solid black;margin-right: 10px;margin-bottom: 10px;font-size: 16px;}.left_two{display: inline-block;width: 178px;height: 198px;text-align: center;line-height: 100px;border: 1px solid black;margin-right: 10px;font-size: 16px;}.nav_right{width: 200px;float: right;font-size: 0;}.left_three{display: inline-block;width: 198px;height: 128px;text-align: center;line-height: 100px;border: 1px solid black;margin-bottom: 10px;font-size: 16px;}.foot_url{/* 清除浮动 */clear: both;height: 60px;text-align: center;line-height: 60px;background-color: rgb(171, 149, 149);}</style>
