Apply Style to an XML Document with CSS
Make an in-browser XML document more appealing by applying a CSS stylesheet to it.
Cascading Style Sheets (CSS) is a W3C language for applying style to HTML, XHTML, or XML documents (http://www.w3.org/Style/CSS/). CSS Level 1 or CSS/1 (http://www.w3.org/TR/CSS1) came out of the W3C in 1996 and was later revised in 1999. CSS Level 2 or CSS/2 (http://www.w3.org/TR/CSS2/) became a W3C recommendation in 1998. CSS/3 is under construction (http://www.w3.org/Style/CSS/current-work). Understandably, CSS/1 enjoys the widest support.

The beginning part of an XML document, before the document element begins, is called a prolog.
Here is an example of a PI:
<?xml-stylesheet href="time.css" type="text/css"?>
A PI is bounded by
