 <p>Usualmente se puede considerar que las páginas HTML tienen dos dimensiones, porque el texto, las imágenes y otros elementos son organizados en la página sin superponerse. Hay un solo flujo de renderizado, y todos los elementos son concientes del espacio ocupado por otros. El atributo <span class="seoSummary">{{cssxref("z-index")}}</span> te permite ajustar el orden de las capas de los objetos cuando el contenido está siendo renderizado.</p>

 <p>El DOM proporciona características que hacen posible probar los resultados de un media query estructuradamente. Esto es hecho usando la interfaz {{domxref("MediaQueryList") }} y sus métodos y propiedades. Una vez que hayas creado el objeto {{domxref("MediaQueryList") }}, puedes revisar el resultado del query o, como alternativa, recibir notificaciones automáticamente cuando el resultado cambie.</p>
