Style sheets consist of collections of graphic settings, such as color, font, and icon, that are used to render objects and associated attributes in graphic components. Cascading Style Sheets (CSS) provide a powerful mechanism for customizing HTML rendering in a Web browser. The CSS specification originates from the World Wide Web Consortium (W3C) and has the status of a W3C Recommendation.

The CSS mechanism is a great improvement over the .Xdefault resource mechanism of the X Window System. The basic idea remains the same: matching a pattern and setting resource values. The CSS language is intended for HTML rendering: matching HTML tags, and setting style values. XML is also a CSS target, especially in the context of the Scalable Vector Graphic (SVG) specification of W3C.

In JViews TGO, the CSS level 2 (CSS2) Recommendation is transposed for the Java™ language and used to set Bean properties according to the Java object hierarchy and state.

JViews TGO graphic components use CSS to customize the object rendering as well as the graphic component configuration. JViews TGO supplies a large number of predefined ready-to-use CSS properties that apply to both predefined and custom business classes, objects, and attributes of these objects. The predefined representation can be fully customized to achieve the graphic representation that best suits your needs.
