There are two types of Stylesheet language:

1. Cascading Stylesheet language
2. Extensible Stylesheet language

Cascading Style Sheets:

CSS is considered about style a document controlled in a markup language XML and HTML including SVG and XHTL. And it was made for that purpose. The code CSS is non-XML syntax to outline the style info for the assorted components of the document that it styles. The language to structure a document is a pre limit to CSS. A markup language, like HTML and less XUL, may outline some primitive elements to style a document, e.g. <ABC> to bold i.e. it seen in dark color.

CSS post styles a document to "paged media" or "screen media". Screen media, display as a particular page that has a permanent horizontal width but a nearly unlimited vertical height. Scroll is typically the technique of choice for viewing parts of screen media. This is in opposition to "paged media", that has multiple pages, each with particular fixed vertical and horizontal dimensions. To style page media involve a range of complexity that display media doesn't. Since CSS was designed originally for screen media, its paged facilities lacked. CSS version 3.0 provides latest features that permit CSS to extra effectively style documents for page show.

Extensible Stylesheet Language:

XSL has developed radically from its 1st design into something totally different from its original purpose. The first concept for XSL was to make an XML based style language pointed at paged display media. The method they used to do this job was to split the method into 2 distinct steps. First, the XML document would be changed into an intermediate form. The method for performing this change would be ruled by the XSL Stylesheet, as outlined by the XSL design.

Nevertheless in the procedure of planning the transformation step, it was noticed that a universal XML alteration language would be useful for at least simply making a display of an XML document. A new working group was divided off from the XSL working group and XSLT language became somewhat that was considered separate from the styling information of the XSL FO document. Even that divide was extended when XPath became its personal different design though at rest powerfully joined to XSLT. The mix of XSLT and XSL-FO creates a forceful styling language, though much more complicated than CSS. XSLT is a turing total language while CSS is not. In addition, XSLT is actually capable of making content, for example mechanically making a table of contents just from chapters in a book, or removing / choosing content, for example only creating a thesaurus from a book. XSLT1.0 with XSLT2.0 is really capable of generating multiple documents also like dividing the chapters in a book into their own individual pages.
