Class CssMediaQuery

java.lang.Object
com.oorian.css.CssElement
com.oorian.css.CssMediaQuery
public class CssMediaQuery extends CssElement
Represents a CSS @media query for applying conditional styles based on device characteristics.

CssMediaQuery allows you to define responsive CSS rules that apply only when certain conditions are met, such as screen width, device orientation, or color capability.

Example usage:

 CssMediaQuery mobile = new CssMediaQuery("@media (max-width: 768px)");
 mobile.addRule(new CssRule(".sidebar", "display: none"));
 mobile.addRule(new CssRule(".content", "width: 100%"));

This generates:

 @media (max-width: 768px) { .sidebar { display: none; } .content { width: 100%; } }

Media queries can be nested by using addMediaQuery(CssMediaQuery).
