Parallax Item in a Squarespace Marquee template

Hi there, I manage to add a logo in my page description using this custom CSS: https://answers.squarespace.com/questions/23543/marquee-add-logo-to-first-index-image.html

But the image is overlapping the description. How can I move only the logo up or do something else to get a visual result similar to this: http://www.johannesleonardo.com/ (Adidas original is never finished)

Here's my site: https://ronaldo-tavares-bmtl.squarespace.com/portfolio/
(to access just click VISITOR and type the code it gives you)

I'm an art director/designer and I don't know much about coding... please!!! Any help?

Many thanks.
