ZUSS 介绍
ZUSS（ZK用户界面样式表）是对CSS的扩展。ZUSS是向后兼容使用CSS的，同时延长了它的变量，混入，嵌套规则，表达式，条件内容，并与现有的CSS语法的Java方法。
ZUSS (ZK User-interface Style Sheet) is an extension to CSS. ZUSS is backward
compatible with CSS, while extending it with variables, mixins, nested rules,
expressions, conditional content, and Java methods with existing CSS Syntax.
Design Goals
- Extend CSS to make it easy to write sophisticated CSS rules
- High performance server-side processing with small foot print
- Seamlessly integration with Java without the need of JavaScript interpreter
The first implementation is Java, and it depends nothing but JDK. It shall be
straighforward to port to different languages.
鸣谢
LESS和Sass启发ZUSS。不像LESS和上海社会科学院，ZUSS文件的处理，将不需要JavaScript或Ruby解释器。
