Class CssStyleSheet

java.lang.Object
com.oorian.css.CssStyleSheet
public class CssStyleSheet extends Object
Represents a dynamic CSS stylesheet that can contain rules, keyframes, media queries, and nested stylesheets.

This class provides a programmatic way to build CSS stylesheets in Java. It supports hierarchical organization with nested stylesheets and can generate complete CSS output as a string. The stylesheet is lazily initialized when first converted to a string.

Features:

  • Add CSS rules with selectors and style declarations
  • Define keyframe animations
  • Create media queries for responsive design
  • Nest child stylesheets for modular organization
  • Lazy initialization for optimal performance

Usage:


 CssStyleSheet sheet = new CssStyleSheet();
 CssRule rule = new CssRule(".myClass");
 rule.setColor(Color.BLUE);
 sheet.addRule(rule);

 String css = sheet.toString();
