CSS (Cascading Style Sheets) and XSL (Extensible Stylesheet Languages) are some of the most widely used forms of style sheet languages in the industry of web design, which are also standardized by W3C. According to a number of Web design Philippines experts, though CSS is considered as the most popular styling language used in the market, XSL is better known for its powerful styling capabilities than CSS.
XSL vs CSS
XSL or Extensible Stylesheet Language is a language which was first used to as an attempt to bring the functionality of DSSSL, particularly in the area of print and high-end typesetting, to XML. XSL, however, has evolved drastically from its initial design into something very different from its original purpose.
XSL today is mostly known as a term used to define a family of style sheet languages. This includes the popular XSL-FO (XSL Formatting Objects) and XSLT (XSL Transformations). According to many Web design Philippines experts, the combination of XSLT and XSL-FO creates a powerful styling language. However, this may be too complex for CSS users.
The XSL-FO is also known for its strength compared to CSS. XSL-FO is unlike CSS in that the XSL-FO document stands alone. However, the complexity of XSL-FO is a problem, largely because implementing an FO processor is very difficult. These are the reasons why CSS is still known as the most widely used style sheet language in the market.
Other style sheet languages
However, other than these styling languages, a number of style sheet languages were also introduced in the past and in today's market. These include DSSSL (Document Style Semantics and Specification Language), which is also one of the 3 standardized style sheet languages used in the market.
DSSSL or Document Style Semantics and Specification Language was first used as a styling language for SGML, which was eventually used for style websites. Other than DSSSL, other non-standardized styling language were also introduced. These include:
JSSS or JavaScript Style Sheets, which was proposed by Netscape Communications Corporation. According to many Web design Philippines experts, it was an alternative to the Cascading Style Sheets (CSS) technology. However, Netscape stopped promoting JSSS, instead focusing on the rival CSS standard. Many of today's Web developers not even being aware of its existence. The proposed standard was not finished.
Sass or Syntactically Awesome Stylesheets is best described as a meta-language on top of CSS, and is meant to abstract CSS code and create simpler stylesheet files. Another is FOSI or Formatted Output Specification Instance, a styling language similar to DSSSL which was used for SGML. It was later used for XML.
