Custom slider. Relative arrow buttons

Hi guys,
I want to achieve a different look for my slider. I want overlapping texts beyond the mask, but to act as if they are in the slide and change upon changing the slide.
I want some text to be outside of the mask and the slider arrow button to move/scale on different breakpoints along the the image, not the mask. I hope this is clear enough.

I am sharing my project. Scroll to slider black section.

Thanks a lot,

Best! Elli
