public class CSSStyleSheetFilter
extends Object

Rewrites a CSS stream so that it can be used by a portlet in a portal page without affecting other portlets or the portal page itself. The following transformations are executed:

• Name-space all CSS selectors by prefixing them with a given string (e.g. the identifier of the portlet content container)
• Rename identifiers used in selectors to ensure their uniqueness inside the portal page
• Rewrite import URLs so that CSS style sheets are requested through the portlet
