Image and Text overlay in sticky section

Hello, 

I've created a Sticky Section on a site I'm working on: 
https://dragonfly-star-7hgp.squarespace.com/

And in this section I'd like some of the images to sit ON TOP of the text as you scroll - rather than below, to give it a layered effect. Specifically the images in the below screenshot. 

Any ideas on how to do this - I tried a few custom code snippets I found in the forums, but nothing seemed to work. 

Any ideas? Thank you

Like this?

.fe-block-8d004890984c1f6d7050 {
    z-index: 999999999999999999;
}

Yes! Thank you, that worked perfectly! 

I replicated that code for some of the other image blocks, and it worked exactly how I wanted it to. 

Thank you

@holahannah could you please share the code you used to create the sticky effect 🙂
