修复IE浏览器的话，试试如下操作
1、单击“开始-->运行”，在“运行”窗口中，输入regsvr32 actxprxy.dll，然后“确定”，接着会出现一个信息对话框“DllRegisterServer in actxprxy.dll succeeded”，再次点击“确定”；
2、再次打开“运行”窗口，输入regsvr32 shdocvw.dll，单击“确定”；
3、再次打开“运行”窗口，输入regsvr32 jscript.dll，单击“确定”；
4、重新启动Windows系统

PS：CCTV偶尔犯这种错误也正常，它又不是搞WEB的。
有几个例子 分割线隔开html>

接着看页面代码：

<br>ssadfsadfsdfdf</br>
<b class="b4"></b><b class="b3"></b><b class="b2"></b><b class="b1"></b>
当然你也可以用其他的标签<div>或者<span><a>之类，应该也是可以的
