I lifted this from http://developer.freelancedesigners.com/

Web developers usually offer HTML and programming services and create interactive or database driven e-commerce web sites. The difference between a designer and a developer is that a developer usually has more back-end programming skills for building shopping carts and member databases while a designer is more focused on the look and feel of a site.

http://www.dictionary.com definition of HTML
A markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web.

http://www.dictionary.com definition of CSS
An extension to HTML to allow styles, e.g. colour, font, size to be specified for certain elements of a hypertext document. Style information can be included in-line in the HTML file or in a separate CSS file (which can then be easily shared by multiple HTML files). Multiple levels of CSS can be used to allow selective overriding of styles.

http://www.dictionary.com definition of Javascript
(Formerly "LiveScript") Netscape's simple, cross-platform, World-Wide Web scripting language, only very vaguely related to Java (which is a Sun trademark). JavaScript is intimately tied to the World-Wide Web, and currently runs in only three environments - as a server-side scripting language, as an embedded language in server-parsed HTML, and as an embedded language run in web browsers where it is the most important part of DHTML.

JavaScript has a simplified {C}-like syntax and is tightly integrated with the browser Document Object Model. It is useful for implementing enhanced forms, simple web database front-ends, and navigation enhancements. It is unusual in that the scope of variables extends throughout the function in which they are declared rather than the smallest enclosing block as in C.
