Shopify Expert - Fix and Parallax effect

Hello,

How are you ?

Please see my website: https://www.chiarasarena.com

You can see the page is one image background, you can also see the glitch effect and parallax effect when click the "DOWN ARROW".

I own all the code, it's mostly HTML, CSS and JS. I will send it to you.

I want to import the code to my freshly created Shopify store: https://chiarasarena.myshopify.com/

It has nothing in it, just default theme called "Dawn" is installed.

Here is what I want in details, please kindly check all modifications in this image: https://i.imgur.com/eS0Nh0B.jpg

I made it on Paint but it's just to explain you.

I want these following pages done and responsive on my Shopify store with the glitch effect and parallax effect (no reload).

Text slide / Parallax effect from right to left will be applied when click on "SHOP", "BACK TO SHOP", "HOME" and "CONTACT" buttons so content disappear and it shows the specific sections you can see in the image sent instead.

Price: 50€

What is your best timeline for this project ?

Thanks
