在html head中加上这一句代码都可以了：<!--[if IE 6]> <style type="text/css"> /*<![CDATA[*/ html {overflow-x:auto; overflow-y:hidden;} /*]]>*/ </style><![endif]-->position:fixed;
_position:absolute;
right:auto;
left:0px;
_left:expression(eval(document.documentElement.scrollLeft));
_background-image:url(about:blank);
_background-attachment:fixed;
