以下是css：
.con_center{height:300px;width:1200px;margin:0px auto;padding-top:20px; }
#bo{float:left; width:180px;}
.con{float:left;width:900px; height:600px; background:url(../Img/pro1_bg1.png); margin-left:20px;display;margin-top:10px;}
.img_bottom{width:180px; height:80px;padding-left:4px; clear:left;}
.img_top{width:180px; margin-bottom:-5px;}
.nav{float:left;}
.title_top{margin:20px 0 -5px 40px;}

[解决办法]
试试加个text-align:center;
[解决办法]
编码要一致
[解决办法]
使用文档头
[解决办法]
给body加个{margin:0px auto;}
[解决办法]
别管ie6啦，过时了
[解决办法]
第一行必须保证是dtd声明，否则ie6会进入怪癖模式
[解决办法]
第一行必须添加dtd声明，没有dtd的结果就是ie6,7,8,9以ie5的方式来渲染页面，就是ie7,8,9里边的f12打开后 文档模式下的quirks模式。这个模式会造成css盒模型计算错误,margin:0 auto; 不能居中。
只能在body{text-align:center;}这样来居中，但是这会使页面上所有的内容都居中，所以请添加dtd
dtd必须是页面的第一行出现。
xhtml-dtd:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
html5-dtd:
<!DOCTYPE html>
[解决办法]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
text-align:center;
加上这两个试试，兼容
[解决办法]
body{margin:0 auto;width:980px;}
[解决办法]
同意添加DTD
[解决办法]
要加宽度，否则无用
[解决办法]
10楼，12楼正确。
[解决办法]
body{
text-align:center;
}
需要居中的容器：text-align:left;
