HTML - HyperText Markup Language

HTML is a set of special codes referred to as "tags," which instruct a web browser how to display your information and images.

Style Sheets - Cascading Style Sheets

Style sheets describe how an HTML tag should be render by the web browser. You can change the web browser's default rendering of attributes such as colors, borders, margins, etc., and create you own.

Scripts - Client Side Programming

Scripts are programs that are embedding in the HTML page. These can tell the web browser how to react to the viewer actions such a placing the mouse over an HTML tag. These can also run independent of the view's actions and perform some task at a given time or interval.
