我有一个小问题,我希望我的页脚以 position: absolute 保留在屏幕底部。但是我将它放在屏幕中间的 margin: auto 不再起作用了。

HTML:

<!DOCTYPE html>
<html>
<head>
<meta http-equiv='Content-Type' content='Type=text/html; charset=utf-8'>
<link rel="shortcut icon" href="../IMAGES/favicon.ico">
<title>TEST</title>
<link href='http://fonts.googleapis.com/css?family=Source+Sans+Pro' rel='stylesheet' type='text/css'>
<link rel="stylesheet" href="../css/stylesheet.css">

<div id="header">
<div id="logo">
<img src="../IMAGES/logo.png" />

CSS:

/* PAGE LAYOUT */

background-image: url(../IMAGES/background.png);

font-family: 'Source Sans Pro', serif, sans-serif;
}

.clear

clear: both;

}

.link:hover

text-decoration: underline;
}

/* CONTENT */

#content
{

margin: auto;

position: relative;
}

/* FOOTER */

#footer
{
width: 1100PX;
height: 50px;
position: absolute;
bottom: 0;
margin: auto;
background-color: #282828;
}

#copy
{
width: auto;
float: right;
margin-right: 5px;
height: 50px;
line-height: 50px;
}

最佳答案

因为您知道页脚的宽度 (1100px),所以您可以执行 left:50%;margin-left:-550px 使其居中。

示例:将绝对定位的元素居中

因此,页脚将变为:

#footer
{
width: 1100PX;
height: 50px;
position: absolute;
bottom: 0;
left:50%; /* Add this */
margin-left:-550px; /* Add this (this is half of #footers width) */
background-color: #282828;
}

如果您希望元素在用户向下滚动时停留在页面底部,请使用 position: fixed 而不是 position:absolute
