抱歉,如果之前有人问过这个问题,但我阅读并没有看到我的错误。我尝试将 #wrapper 与 margin:0 auto 居中;但没有任何反应......宽度也已设置。
这是 CSS:我希望孔页居中
@charset "utf-8";
body {
margin-left:0px;
margin-top:0px;
margin-right:0px;
margin-bottom:0px;
padding:0;
background-color:#000000;
text-align:center
}
#wrapper {
width: 901px;
***margin: 0 auto;***
}
#header {
background-image: url(images/banner.jpg);
background-repeat: no-repeat;
float: left;
height: 233px;
width: 901px;
}
#menu {
font-family: Arial, Helvetica, sans-serif;
background-image: url(images/menu.gif);
background-repeat: no-repeat;
text-align: center;
word-spacing: 70px;
padding-top: 17px;
float: left;
height: 33px;
width: 901px;
}
#main {
float:left;
height:auto;
width:901px;
}
#leftcol {
float:left;
height:auto;
width:300px;
padding-top:5px;
padding-right:0px;
padding-bottom:0px;
padding-left:30px;
}
#rightcol {
float:right;
height:auto;
width:500px;
padding-right:35px;
margin-right:0px;
}
#footer {
font-family:Arial, Helvetica, sans-serif;
font-size:x-small;
float:left;
height:250px;
width:900px;
color:#666666;
clear:both
}
还有html:
这是基本的html文件
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="wrapper">Content for id "wrapper" Goes Here</div>
<div id="header">Content for id "header" Goes Here</div>
<div id="menu">Content for id "menu" Goes Here</div>
<div id="main">
<div id="leftcol">Content for id "main" Goes Here</div>
<div id="rightcol">Content for id "rightcol" Goes Here</div>
<div id="footer">Content for id "footer" Goes Here</div>
</div>
</body>
</html>
