IE下怎么设置frameset的背景色

IE下如何设置frameset的背景色
<frameset rows="80,*" cols="*" frameborder="yes" border="3" bordercolor="#000000" style="background-image:url('m.jpg') " framespacing="0">
  <frame src="UntitledFrame-3.htm" name="topFrame" scrolling="NO" noresize>
  <frameset rows="*" cols="150,*" framespacing="0" frameborder="1" bordercolor="#000000" border="1">
  <frame src="UntitledFrame-1.htm" name="leftFrame" scrolling="auto" >
  <frame src="UntitledFrame-2.htm" name="mainFrame">
  </frameset>
</frameset>
这段代码在firefox可以正常显示背景图片,IE6下无法显示背景图片

[解决办法]

HTML code

<frameset rows="80,*" cols="*" frameborder="yes"  border="3" bordercolor="#000000" style="background:url('m.jpg') " framespacing="0">   <frame src="UntitledFrame-3.htm" name="topFrame" scrolling="NO"  noresize>   <frameset rows="*" cols="150,*" framespacing="0" frameborder="1" bordercolor="#000000" border="1">     <frame src="UntitledFrame-1.htm" name="leftFrame" scrolling="auto"  >     <frame src="UntitledFrame-2.htm" name="mainFrame">   </frameset> </frameset>
