实现代码如下：

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
<style>
.main {
    width: 800px;
    height: 600px;
    border: 2px solid #c0c4c7;
    margin:0px auto;
    padding:10px;
}
.top {
    height: 100px;
    padding:0;
    margin:0;
    background-color: #52a8d0;
}
.center {
    width:100%;
    padding:0;
    height: 380px;
    margin: 10px auto;
}
.center_left {
    width: 595px;
    height: 380px;
    background-color: #d24ca4;
    float: left;
}
.center_right {
    width: 195px;
    height: 380px;
    background-color: #d24ca4;
    float: right;
    margin-left: 10px;
}
.bottom {
    clear:both;
    height: 100px;
    background-color: #54add7;
    margin: 0px auto;
}
</style>
</head>
<body>
<div class="main">
  <div class="top"></div>
  <div class="center">
    <div class="center_left"></div>
    <div class="center_right"></div>
  </div>
  <div class="bottom"></div>
</div>
</body>
</html>

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <title>Title</title>
    <style>
            *{
                padding: 0;
                margin: 0;
            }
            .wrap{
                width:800px;
                margin:0 auto;
                border:1px solid #ccc;
                padding:10px;
            }
        .header{
            height: 100px;
            background-color: #52a8d0;
        }
        .container{
            height: 380px;
            margin:10px 0;
            overflow: hidden;
        }
        .box-center-left{
            width: 595px;
            height: 380px;
            background-color: #d24ca4;
            float: left;
        }
        .box-center-right{
            width: 195px;
            height: 380px;
            background-color: #d24ca4;
            float: right;
            margin-left: 10px;
        }
        .footer{
            height: 100px;
            background-color: #54add7;
        }
    </style>
</head>
<body>
    <div class="wrap">
        <div class="header"></div>
        <div class="container">
            <div class="box-center-left"></div>
            <div class="box-center-right"></div>
        </div>
        <div class="footer"></div>
    </div>
</body>
</html>

最关键的记得 clear:both或者设置heigth，清除浮动
