asp链接CSS样式，本页跳转链接加粗。

本页刷新跳转，想tu.asp?type=xiaoxue时，“小学”加粗；tu.asp?type=zhonhxue时，“中学”加粗；

tu.asp
<!--#include file="conn.asp" -->
<%
rk = Request.QueryString("type")
set rs=Server.CreateObject("ADODB.Recordset")
sql="select * from [zaixianliuyan] where type='"&rk&"' ORDER BY ftime DESC"
rs.open sql,conn,1,1
%>
.................
<a href="tu.asp?type=xiaoxue">小学</a> <a href="tu.asp?type=zhonhxue">中学</a> <a href="tu.asp?type=gaozhong">高中</a>

tu.asp
<!--#include file="conn.asp" -->
<%
rk = Request.QueryString("type")
set rs=Server.CreateObject("ADODB.Recordset")
sql="select * from [zaixianliuyan] where type='"&rk&"' ORDER BY ftime DESC"
rs.open sql,conn,1,1
%>
<style>
a.active{font-weight:bold;}
</style>
<a <%if request("type")="xiaoxue" then response.write "class="active" end if%> href="tu.asp?type=xiaoxue">小学</a> <a <%if request("type")="zhonhxue" then response.write "class="active" end if%> href="tu.asp?type=zhonhxue">中学</a> <a <%if request("type")="gaozhong" then response.write "class="active" end if%> href="tu.asp?type=gaozhong">高中</a>
