Fading Background avec JQuery

Bonjour,

j'ai utilisé deux scripts jquery :

un premier pour lancer une fenêtre modale après un click sur le bouton "Subscribe Now"
un deuxième pour créer une animation lorsque l'on clique sur les des menus au centre.

Les deux fonctionnent séparement très bien.
Le souci c'est que j'aimerais que dans la seconde animation, le background réalise un fade in/fade out comme dans le premier script, ne m'y connaissant pas assez en Jquery, j'ai un peu (beaucoup en fait) de mal à intégrer cet effet dans cette partie du script.

Le premier effet se trouve dans un fichier externe reveal/jquery.reveal.js
le second se trouve en bas du code source de la page html

le problème que j'ai eu c'est que qd j'arrivais à réaliser cet effet sur le menu, celui sur le bouton Subscribe Now ne fonctionnait plus! :$

voici le lien de ma page test :

Merci d'avance!

voici le code javascript inséré dans la page html
