OVERVIEW

This specification defines Cascading Style Sheets, level 2 revision 1 (CSS 2.1) . CSS 2.1 is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS 2.1 simplifies Web authoring and site maintenance. CSS 2.1 builds on CSS2 [CSS2] which builds on CSS1 [CSS1] . It supports media-specific style sheets so that authors may tailor the presentation of their documents to visual browsers, aural devices, printers, braille devices, handheld devices, etc. It also supports content positioning, table layout, features for internationalization and some properties related to user interface.¹

CSS 2.1 portion of the Internet is still developing sites with a fixed and/or static approach to presentation. With the success of several social networking sites, performance and design scalability are no longer resigned to enterprise level class applications. Social networks and blogs demand a dynamic publishing solution for interactive content. Web development now requires sites to address publicly approved, fixed content and a need for interactive content creation. Whether one decides to purchase a complete packaged solution or have one designed around their needs and scale to meet future needs depends on the client.
