我去掉边框 但是设置边框颜色不管用都是白的，
加上边框，颜色是有了，但是边框有3d的凸感
我想去掉边框的3d凸感，有想边框有颜色，请教css设置

研究了几个小时终于找到答案了，按照你的代码应该这样写。
<frameset rows= "69,* " cols= "* " border= "0 " frameborder= "1 " framespacing= "5 " >
<frame src= "index_top.jsp " name= "topFrame " scrolling= "NO " noresize frameborder= "no " bordercolor= "#CADAE8 ">
<frameset cols= "160,* " frameborder= "1 " framespacing= "5 " >
<frame src= "index_left.jsp " name= "leftFrame " id= "leftFrame " scrolling= "NO " frameborder= "no " bordercolor= "#CADAE8 ">
<frame src= "index_main.jsp " name= "mainFrame " id= "mainFrame " frameborder= "no " bordercolor= "#CADAE8 ">
</frameset>
</frameset>
