Sí, exacto. Para que el diseño móvil se vea **perfecto** (como la versión mejorada con las "píldoras" y todo centrado) y no se vea raro como en la captura anterior, sigue este paso:

1.  Abre tu archivo `assets/css/styles.css`.
2.  Ve **al final de todo el archivo**.
3.  Pega el bloque que te di justo después de la última llave `}`.

**¿Por qué al final?**
Porque en CSS, lo que está más abajo tiene prioridad. Al pegarlo al final, te aseguras de que sobrescriba cualquier estilo "viejo" o genérico que pudiera haber quedado en el código anterior y fuerce el diseño limpio y centrado que diseñamos para móvil.

Aquí tienes el bloque otra vez por si necesitas copiarlo rápidamente para pegarlo al final:
