大神能解释下么
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">

<style>
#container {
width:1000px;
background:gray;
}
#header {
height:120px;
background:orange;
}
#main {
height:600px;
background:green;

#lside {

float:left;
}
#rside {
height:600px;
width:300px;
background:purple;
float:right;
}
#footer {
height:120px;
background:blue;
}
</style>
</head>
<body>
<div id = "container">
<div id = "header"></div>
<div id = "main">
<div id = "lside"></div>
<div id = "rside"></div>
</div>
<div id = "footer"></div>
</div>
</body>
</html>
为什么去掉header时最上面没有灰色填充 container不包括header么

HTML结构没错，很可能是body默认的margin: 8px导致的，你加上这句样式：body {margin: 0;}
