设置frameset的framespacing的颜色
例子如下
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<frameset border="0" frameborder="1" framespacing="20" cols="110,*">
<frame border="0" frameborder="0" src="about:blank">
<frame border="0" bordercolor="#6699cc" frameborder="0" src="about:blank">
</frameset>
</html>
<html xmlns="http://www.w3.org/1999/xhtml">
<frameset border="0" frameborder="1" framespacing="20" cols="110,*">
<frame border="0" frameborder="0" src="about:blank">
<frame border="0" bordercolor="#6699cc" frameborder="0" src="about:blank">
</frameset>
</html>
另一个最简示例
<frameset frameborder="1" framespacing="20" cols="110,*">
<frame src="about:blank">
<frame bordercolor="#6699cc" src="about:blank">
</frameset>
<frame src="about:blank">
<frame bordercolor="#6699cc" src="about:blank">
</frameset>
关键是设置frameset的frameborder="1",和其中一个frame的bordercolor="#6699cc"
