Web Development Boot Camp
Course Description
Overview
This bootcamp is designed to take a novice or beginning Web Designer all the way from the basics of page markup through the development of sophisticated, interactive client-side web applications. This class may be of particular interest to those with IT job skills in declining technical areas who are looking to re-tool to enter into the growing industry of web application development.The student will initially learn how to create HTML and XHTML-based web pages that are attractive, easily modifiable and re-usable. An emphasis is placed on separation of the page content from the design and presentation of that content using Cascading Style Sheets (CSS). These are the essential skills required for the development of “static” web pages.
Today, these static pages are often enhanced to allow the user to interact with and “customize” the presentation of the content. Client-side JavaScript and the manipulation of the page via the Document Object Model (DOM) is the mechanism used to accomplish this important aspect of contemporary web application development. In this section of the bootcamp the students learn the fundamental and advanced features of JavaScript programming - how to develop scripts that are modular, easily maintainable, and able to manipulate the content displayed in different types and versions of browsers.
The content that is used to customize personal web pages is usually received from a server-side application in eXtensible Markup Language (XML) format. In this next section of the bootcamp, the student will be given a comprehensive overview of XML, with hands-on experience in creating and manipulating XML specifications and documents.
The final section of the bootcamp will “pull it all together” with AJAX – the Asynchronous JavaScript and XML technique. AJAX is the combination of all the technologies taught in this bootcamp applied to create rich interactive web applications – X/HTML, CSS, JavaScript, and XML. This section will show the student how to send and retrieve XML documents from a server, extract data (XML) from that document (using JavaScript), and subsequently use that data to modify the content (X/HTML) and display (CSS) of the local web page.
