Shopify / Wordpress - Migrate small code / convert

Hello,

How are you ?

Please check my website in WORDPRESS: https://www.chiarasarena.com/

You can see the glitch effect.

I use this theme: https://themeforest.net/item/gravity-multipurpose-coming-soon-theme/19758632
And this version: https://creazione.avanzare.co/gravity_wp/demo/?bg=glitch

I have all code.

I want this glitch effect added to my freshly new created Shopify store (there is nothing in it yet).
Then keep the glitch effect for all pages, is that possible ?

Can you do fast in few minutes/hours from now ?

Any questions please let me know.

Thanks
