早上好， 我有一个css代码让我发疯，因为我无法纠正它！ 这是代码：

这是主要的页脚css代码：
/* Start Mian Footer */
div#main_footer
{
color: #ffffff;
background:#3B5998;
border-top-left-radius: 7px;
border-top-right-radius: 7px;
width: 900px;
height: 5px;
position: absolute;
top: 100%;
bottom: 0;
padding-top: 5px;
padding-bottom: 15px;
padding-left: 15px;
padding-right: 15px;
font-size: 8pt;
}
div#main_footer a
{
color: #ffffff;
text-decoration: none;
}
/* End Main Footer */
答案 0 :(得分：0)
要将页脚保持在正确的位置，只需更改div#main_footer样式，修改这些行：
position: fixed;
/* top: 100%;*/
