网站导航栏下拉菜单偏移问题

[sdqingdaolibo]

网站导航栏当电脑分辨率改变时有偏移，这是一个部分的代码，请大家帮忙看看。
<DIV class=menu id=Layer3 onmouseover="this.style.visibility=''"
style="Z-INDEX: 1; LEFT: 345px; VISIBILITY: hidden; WIDTH: 60px; POSITION: absolute; TOP: 139px; HEIGHT: 268px"
onmouseout="this.style.visibility='hidden'">
<TABLE cellSpacing=1 cellPadding=0 width="100%" border=0>
<TBODY>
<TR>
<TD bgColor=#02602c>
<TABLE cellSpacing=0 cellPadding=0 width="100%" border=0>
<TBODY>
<TR>
<TD><IMG height=5 src="" width=1></TD></TR>
<TR>
<TD class=sub_nav_green
onmouseover="this.className='sub_nav_red';this.style.cursor='hand'"

看你那个DIV的样式就知道问题了

<DIV class=menu id=Layer3 onmouseover="this.style.visibility=''"
style="Z-INDEX: 1; LEFT: 345px; VISIBILITY: hidden; WIDTH: 60px; POSITION: absolute; TOP: 139px; HEIGHT: 268px"

建议用JS获取到客户端的分辨率之后判断top left right的位置大小
