/* Definicion  de terminos en caso de no saber para que son: 

box-sizing: border-box hace que el padding y el border se incluyan dentro del ancho y alto total de un elemento, lo que facilita el diseño y evita problemas de desbordamiento. 

margin: 0; elimina el margen predeterminado que los navegadores aplican a los elementos, lo que ayuda a mantener un diseño consistente, osea elimina el espacio entre los elementos y el borde del navegador.

padding: 0; elimina el padding predeterminado que los navegadores aplican a los elementos, lo que ayuda a mantener un diseño consistente, osea elimina el espacio entre el contenido de un elemento y su borde.

scroll-behavior: smooth; hace que el desplazamiento a anclas dentro de la página sea suave en lugar de instantáneo, lo que mejora la experiencia del usuario al navegar por la página.

overflow-x: hidden; oculta cualquier contenido que se desborde horizontalmente.

inset: 0; Sirve para no tener que poner top: 0; left: 0; right: 0; bottom: 0, esto hace que el elemnto ocupe toda la pantalla, es decir, se extienda desde el borde superior hasta el borde inferior y desde el borde izquierdo hasta el borde derecho del contenedor padre.
