HTML 4.01 HTML 4.01 is an important Web standard, and it is very different from HTML 3.2. When font-like tags and color attributes were added to HTML 3.2, it gradually became a nightmare for developers. The process of developing websites where font information had to be added to each individual page became a long and expensive ordeal. With HTML 4.01, all formatting information can be moved out of the HTML document and into a separate style sheet. Another reason why HTML 4.01 is important is because of XHTML 1.0, the latest HTML standard that is a re-expression of HTML 4.01 as an XML application. Using HTML 4.01 in your pages ensures easy upgrades from HTML to XHTML in the future. Please make sure you are using the latest HTML 4.01 standard. Cascading Style Sheets (CSS) XHTML - The future of HTML XHTML 1.0 is the latest HTML standard from W3C. It became an official recommendation (Recommendation) on January 26, 2000. W3C Recommendation means the stability of its specification, and its specification has now become a Web standard. XHTML is a refactored version of HTML 4.01 using XML and can be put into use immediately in existing browsers by following some simple guidelines. XML - A tool for describing data Extensible Markup Language (XML) is not a replacement for HTML. In future web development, XML will be used to describe and store data, and HTML will be used to display data. Our most appropriate description of XML is a cross-platform, software and hardware independent, information storage and transmission tool. We believe that XML is as important as HTML as it is fundamental to the web, and that XML will become the most important data processing and transmission tool. XSLT - a tool for users to transform data Future websites will have to pass data in different formats to different browsers and to other web servers. XSLT is a new W3C standard that converts XML data into different formats. XSLT can convert XML files into a format recognized by browsers, such as HTML, or WML - a markup language used on many handheld devices. XSLT can also add elements, remove, rearrange, and sort elements, test and determine which elements are displayed, and more. Client-side scripting Client-side scripting Scripting is a type of programming regarding the behavior of an Internet browser. You should learn JavaScript to be able to deliver more dynamic website content: JavaScript is a programming tool for HTML designers -------------------------------------------------- ---------------------------------- Server-Side Scripting Server-side scripting is related to Internet server programming. You should learn server-side scripting so you can deliver more dynamic website content. With server-side programming, you can: Dynamically edit, modify, or add web page content Respond to queries or data submitted by users from HTML Access data or databases and return the results to the browser Access files or XML data and return the results to the browser Convert XML to HTML, and Return results to the browser Customize pages for different users to improve page usability Provide security and access control for different web pages Design different outputs for different types of browsers Minimize network traffic -------------------------------------------------- ---------------------------------- Manage Data with SQL Structured Query Language (SQL) is the universal standard for accessing databases such as SQL Server, Oracle, Sybase, and Access. Knowledge of SQL is extremely valuable to those who wish to store and extract data from databases. Any web administrator should understand that SQL is a truly appropriate engine for databases on the web.
HTML is the language of the web, and every web developer needs to have a basic understanding of it.

Styles define how HTML elements are displayed, similar to the role that the font tag plays in HTML 3.2. Styles are usually stored in files outside of the HTML document. External style sheets give you the ability to change the look and layout of all pages within your website simply by editing a simple CSS document. If you've ever tried to make something like change the font or color of all page titles on your site at once, you'll understand how CSS can do more with less.

The creators of HTML are usually not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put some JavaScript code snippets into their HTML pages.
JavaScript can put dynamic text in HTML pages. A JavaScript language like this can write variable text in HTML pages: document.write("h1" + name + "/h1")
JavaScript can react to events. You can set JavaScript to occur when an event is executed, such as when the page is loaded or when the user clicks on an HTML element.
JavaScript can read and modify HTML elements
JavaScript can read and modify the content of HTML elements
JavaScript can be used to validate data. JavaScript can be used to validate form data before the form is submitted to the server. This ensures that the server handles the data correctly.
