很多时候，在布局中需要统一样式，又不可能挨个修改，于是就用到了CSS的统一样式。
写一个公用的样式，需要的东东一起调用。如果需要修改样式，则只需要修改该公用样式即可。
下面简单说一下创建并引用CSS样式的几个进本步骤：
1、现在工程的WebContent目录下创建一个新文件夹，命名为style(这个随意)。
表明我们这个文件夹里放的是CSS样式文件。
2、在刚刚创建的style文件夹内右键-New-Other选择创建CSS文件，并命名。我这里命名为mystyle.css.
3、在这个css样式文件中自定义一个样式。
.pp { size: 24em; color: red;} 我是这样定义的，可以定义为你想要的样式。
4、引用说明
引用分为两个部分
一个是在JSP文件中引用，另一个是在Html文件中引用，两个稍微有点不同。
在JSP文件中引用：
<head> <link href="${pageContext.request.contextPath}/style/mystyle.css" rel="stylesheet"></head> 在Html文件中引用：
<head> <meta charset="UTF-8"> <link href="style/mystyle.css" rel="stylesheet"></head>
通过对比可以发现不同点在${pageContext.request.contextPath}关于工程的路径上
5、开始引用(JSP、Html这两个是相同的)
<form name="myForm" action="/WebTest001/myServlet" method="post"> <p class="pp">这个是CSS练习</p> <input class="pp" type="button" value="send" onclick="send();"></form>

After reading it, you can easily deal with various caching problems, allowing your users to always experience the freshest content. Let’s talk about the basics first. To put it bluntly, in order to improve access speed, the browser or server stores some static resources (such as pictures, CSS, JS) or page content.

The new version is online,
