求帮助求解决啊，催的紧啊

做了个登录页，开始底部有空白，加了个js高度控制，后来问题是在兼容模式下图片各种错位，求高手帮忙解决啊，我初学不太熟练，或者帮我改成div+css的，谢谢各位，急用非兼容模式是这样：
显示正常
兼容模式下就成了这样子：下面是代码：----------------------分割线-------------------------------------

解决方案 »

  1.   

    。这个时候你就要用到FireFox的Dbug了
      

  2.   

    你这样比较一下
    login_03.gif和login_09.gif所在单元格的样式有没有什么差异，如果有差异调整过来，因为现在是这两幅图在纵向对齐上，有不同。我看你03所在的那个单元格好像有个class="ler"的样式，可以细分析一下。
      

  3.   

    FF的debug可以尝试着修改CSS   挺不错的 我现在和LZ一样 前后以前
      

  4.   


    美工神马的不管这事啊，伤不起
    1、  <td class="ler" background="login_03.gif" valign="top" >
    2、 function setH() {
            var curHeight = $(window).height();
            var trs = $("#tabid .ler").parent().siblings();
            var t_d_height = (curHeight - $("#tabid .ler").height()) / 2;
            trs.eq(0).find("td").height(t_d_height);
            trs.eq(1).find("td").height(t_d_height);
        }
    3、body
            {
                margin: 0px;
                overflow: hidden; 
    /*height: 640px;*/        
            }

    按照你的方法果然成功了，三克油啊，万分感谢
