Implementing CSS and JavaScript in JSP File

     

This example shows how to implement css and JavaScript in jsp. Here we have created three main files that is cssScript.jsp, validate.js and style.css. 

In "cssScript.jsp" file, the following code imports style.css file from css folder

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

and the code below imports validate.js file from script folder.

<script language="JavaScript" type="text/JavaScript" src="../script/validate.js"></script>

The style.css file is used to implement the style for the jsp page i.e. look and feel for the page and the validate.js file is used for field validation.

Directory Structure of css and script file
