Detailed Description

Abstract rule in a CSS style sheet.

A rule presents CSS style properties that are applied to a selected set of elements.

Use WCssTemplateRule if you would like to use a widget as a template for specifying (and updating) a style rule, using the widgets style properties, or WCssTextRule if you wish to directly specify the CSS declarations.
