Whats the difference between HTML, CSS, Javascipt and XML?
HTML and XML are related because they are both mark-up languages. The difference between the two is, HTML has a pre-defined set of rules while XML allows the user to come up with their own rules. JavaScript is a scripting language. A scripting language is basically a programming language that, instead of needing to be compiled to function, needs what’s called an interpreter. JavaScript is a popular client-side scripting language because most graphical web browsers have built-in interpreters for JavaScript. CSS is a presentation, styling, or formatting language. It is used in conjunction with mark-up languages such as HTML and XML, although CSS is not the only formatting language that can be used with XML. In simpler terms: HTML/XML tells a browser what sort of information is contained in a given web page. CSS tells a browser how to render/present the various blocks of information that are contained in the web page. JavaScript adds more functionality to the web page.
