Drupal is an open-source content-management framework written in PHP used as a back-end framework for websites and is also used for knowledge management and business collaboration. The standard release of Drupal contains basic features common to content management systems, including user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. Drupal runs on any computing platform that supports both a Web server capable of running PHP and a database to store content and configuration.

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.

HTML

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
