font-size: 9pt; font-style: bold;}

1px 1px}
</style>完整的css

50.新建frame
<a

href="javascript:newframe('http://www.163.net/help/a_little/index.html','http://www.163.net/help/a_little

/a_13.html')"><img alt=帮助 border=0 src="http://bjpic.163.net/images/mail/button-help.gif"></a>

51.向文件中写内容
<%@ page import="java.io.*" %>
<%
 String str = "print me";
 //always give the path from root. This way it almost always works.
 String nameOfTextFile = "/usr/anil/imp.txt";
 try
 {
  PrintWriter pw = new PrintWriter(new FileOutputStream(nameOfTextFile));
  pw.println(str);
  //clean up
  pw.close();
 }
 catch(IOException e)
 {
  out.println(e.getMessage());
 }
%>

52.先读文件再写文件
<%@ page language = "java" %>
<%@ page contentType = "text/html; charSet=gb2312" %>
<%@ page import ="java.util.*" %>
<%@ page import ="java.lang.*" %>
<%@ page import ="javax.servlet.*" %>
<%@ page import ="javax.servlet.jsp.*" %>
<%@ page import ="javax.servlet.http.*" %>
<%@ page import="java.io.*" %>
eryrytry
<%
 int count=0;
 FileInputStream fi =new FileInputStream ("count.txt");
 ObjectInputStream si= new ObjectInputStream (fi);
 count =si.readInt();
 count++;
 out.print(count);
 si.close();

 FileOutputStream fo =new FileOutputStream ("count.txt");
 ObjectOutputStream so= new ObjectOutputStream (fo);
 so.writeInt(count);
 so.close();
%>

53.直线型输入框
<INPUT name=Password size=10 type=password style="border-left-width: 0; border-right-width: 0;

border-top-width: 0; border-bottom-style: solid; border-bottom-width: 1; background-color: #9CEB9C">

54.可以将背景改为按钮性状，通过改变css改变属性
<td width="65" align="center" bgcolor="#E0E0E0" onmouseover=this.className='mouseoverBT';

onmouseout=this.className='mouseout';><a href="tm.asp?classid=76"><font

color="#000000">录音笔</font></a></td>
<style>
.mouseoverbt
{
 background-image: url(http://www.yongle.com.cn/img/btbgw64h20y.gif);
 background-repeat: no-repeat;
}
.mouseout
{
 background-color: #E0E0E0;
}
