RESILIO - ESTILOS CSS
=================================================================

Este archivo contiene TODOS los estilos de la aplicación.
CSS (Cascading Style Sheets) sirve para dar estilo (colores, 
fuentes, márgenes, etc.) a nuestra página web.

¿CÓMO SE LEE ESTE ARCHIVO?
---------------------------
- Los bloques que empiezan con .nombre son CLASES
- Los bloques que empiezan con #nombre son IDs (únicos)
- Las propiedades se ponen entre llaves { }
- Las propiedades van en formato: nombre: valor;

VARIABLES CSS (al principio)
----------------------------
:root nos permite crear variables que podemos reutilizar
en todo el archivo. Si quieres cambiar el color verde,
solo lo cambias aquí y se cambia en toda la página.
