/* NOTAS DE ESTUDIO
1. Organización del CSS:
   - Variables (:root)
   - Reset y estilos base
   - Componentes reutilizables
   - Layouts específicos
   - Utilidades
   - Media queries

2. Buenas prácticas:
   - Uso de variables CSS para consistencia
   - Agrupación de propiedades relacionadas
   - Nombres de clases descriptivos
   - Especificidad controlada
   - Transiciones suaves para mejor UX

3. Técnicas avanzadas:
   - Grid para layout responsivo
   - Flexbox para alineación
   - backdrop-filter para efectos visuales
   - Animaciones CSS
   - Media queries para responsividad
