俩列布局(左边固定，右边自适应)，等高布局

俩列布局的三种方式：

方式一：

<!DOCTYPE html>
<html>
<head>
    <title>My Page</title>
    <meta charset="utf-8">
    <style type="text/css">
            *{
                margin: 0;
                padding: 0;
            }

            #left {
                float: left;
                width: 220px;
                background-color: green;
            }

            #content {
                background-color: orange;
                margin-left: 220px;/*==等于左边栏宽度==*/
            }
        </style>
    
</head>
<body>
    <div id="left">Left sidebar</div>
    <div id="content">Main Content</div>

<body>

<div class="container">
