javascript - 如何将 css 与 jsp 结合使用

Question

我有一个用 jsp 构建的网站，我想实现 css。当涉及到 jsp 时，我是一个菜鸟，所以任何关于如何实现它的帮助都会很棒。我知道 css 非常简单，而且我之前在 WordPress 和其他东西中使用过它，但实现对我来说是困难的部分。

这是我的示例 jsp:

<%@page import="java.util.List"%>
<%@page import="ttp.data.Physical_PackageDAO"%>
<%@page import="ttp.data.Physical_Package"%>
<%@page import="ttp.data.Conceptual_PackageDAO"%>
<%@page import="ttp.data.Conceptual_Package"%>
<%@page import="ttp.data.ProductionDAO"%>
<%@page import="ttp.data.Production"%>
<%@page import="ttp.data.VenueDAO"%>
<%@page import="ttp.data.Venue"%>
<jsp:include page="/header.jsp">
  <jsp:param name="title" value="Choose a Production" />
</jsp:include>


<script type="text/javascript">

function doAjax(responseFunc, url, parameters) {
  // create the AJAX object
  var xmlHttp = undefined;
  if (window.ActiveXObject){
    try {
      xmlHttp = new ActiveXObject("MSXML2.XMLHTTP");
    } catch (othermicrosoft){
      try {
        xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
      } catch (failed) {}
    }
  }
  if (xmlHttp == undefined && window.XMLHttpRequest) {
    // If IE7+, Mozilla, Safari, etc: Use native object
    xmlHttp = new XMLHttpRequest();
  }
  if (xmlHttp != undefined) {
    // open the connections
    xmlHttp.open("POST", url, true);
    // callback handler
    xmlHttp.onreadystatechange = function() {
      // test if the response is finished coming down
      if (xmlHttp.readyState == 4 && xmlHttp.status == 200) {
        // create a JS object out of the response text
            var obj = eval("(" + xmlHttp.responseText + ")");
        // call the response function
        responseFunc(obj);
      }
    }

    // create the parameter string

<% Venue v = (Venue)session.getAttribute("currentVenue"); %>
<% List<Conceptual_Package> cpList = Conceptual_PackageDAO.getInstance().getByVenue(v.getId()); %>

What Packages do you want to see?

 <form method="post" action="ttp.actions.Sale3PackAction.action">

在 header.jsp (或者在任何地方生成 <head> 元素:

<link rel="stylesheet" type="text/css" href="/path/to/your/style.css">
