Layout Help angled sections and images

I am new to webflow and I need help getting the computer image to lay on top of the white angled section.

Here is my site Read-Only:

Well, this one taught me something new.

You are doing it correct with the z-index, however, it looks like you need to put the white div in the same div as your image. I guess (at least it appears this way) z-index seems to be working on things within the same div.

It might have something to do with columns, I have personally never used them before.
