hot skills CSS and XSL help ensure consistent presentation of content: W3C's style sheet languages can make life easier for web designers.

This article reports that the style sheets are used to define the presentation of HTML, XHTML and XML. HTML contains presentation elements, but these are being stripped out of XHTML2, so style sheet skills will be needed. The Worldwide Web Consortium (W3C) agrees the specifications for style sheets, which are then incorporated into browsers, authoring tools and other commercial and open source products. The W3C has two style sheet languages: Cascading Style Sheets (CSS), the best known, most widely implemented and easiest to learn, use and maintain and Extensible Style Language (XSL). The W3C has promoted the use of style sheets on the web since it was founded in 1994. Its Style Activity brought together a lot of existing work, particularly on the Standard Generalised Markup Language-based Document Style Semantics and Specification Language. Microsoft Corp. was involved heavily in the early development of XSL, providing five of the 11 authors of the first XSL proposal in 1997. Style sheets are stand alone documents that can be embedded within one document, or applied to a number of documents perhaps all the pages on a website.
