HTML/CSS/JAVASCRIPT/AJAX/JQUERY

HTML (Hyper Text Markup Language)

HTML is a language, which makes it possible to present information on the Internet. What you see when you view a page on the Internet is your browser's interpretation of HTML. To see the HTML code of a page on the Internet, simply click "View" in the top menu of your browser and choose "Source". If you want to make websites, there is no way around HTML. Even if you're using a program to create websites, such as Dreamweaver, a basic knowledge of HTML can make life a lot simpler and your website a lot better.

The good news is that HTML is easy to learn and use. In just two lessons from now you will have learned how to make your first website.HTML is used to make websites. It is as simple as that! In simple word if we go to define it we can say that HTML "mother tongue" of your browser.

CSS (Cascading Style sheets)

CSS is a style language that defines layout of HTML documents. For example, CSS covers fonts, colors, margins, lines, height, width, background images, advanced positions and many other things. Just wait and see!

CSS offers more options and is more accurate and sophisticated. CSS is supported by all browsers today. CSS is used for formatting structured content.

CSS was a revolution in the world of web design. The concrete benefits of CSS include:

• control layout of many documents from one single style sheet;
• more precise control of layout;
• Apply different layout to different media-types (screen, print, etc.);
• Numerous advanced and sophisticated techniques.

Java script

Java script a scripting language developed to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently.

Java script can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies and is an open language that anyone can use without purchasing a license.

JavaScript is a programming language used to make web pages interactive. It runs on your visitor's computer and doesn't require constant downloads from your website. JavaScript is often used to create polls and quizzes.

JavaScript support is built right into all the major web browsers, including Internet Explorer, Firefox and Safari. Provided that the visitors to your site are using web browsers that support JavaScript (most do) and have JavaScript enabled (it is by default), then your JavaScript will run when they visit the page.

JavaScript is an interpreted language, so no special program is required to create usable code. Any plain text editor such as Notepad (one of the Accessories that come in Windows) is quite satisfactory for being able to write JavaScript. That said an editor that colorizes the code to make it easier to see what is what makes it easier to find your mistakes.

AJAX

AJAX stands for Asynchronous JavaScript and XML. AJAX is a new technique for creating better, faster, and more interactive web applications with the help of XML, HTML, CSS and Java Script. Ajax uses XHTML for content and CSS for presentation, as well as the Document Object Model and JavaScript for dynamic content display.

Conventional web application transmit information to and from the sever using synchronous requests. This means you fill out a form, hit submit, and get directed to a new page with new information from the server.

With AJAX when submit is pressed, JavaScript will make a request to the server, interpret the results and update the current screen. In the purest sense, the user would never know that anything was even transmitted to the server.

AJAX is a web browser technology independent of web server software. A user can continue to use the application while the client program requests information from the server in the background. No clicking required only Mouse movement is a sufficient event trigger. Data-driven as opposed to page-driven

 J Query

J Query is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, J Query has changed the way that millions of people write JavaScript.
