Vertically center align lightbox content

I have a CMS content driven lightbox.
But for some reason its vertically aligning all content to the top in the browser when I need it vertically centred.
I have little knowledge of CSS and JS so the options I have tried don’t work.
If anyone has a solution that would be awesome.

(how to share your site Read-Only link)

@danielcobb ~ Hey brother. Did you figure it out? I don’t see the above layout in your “Read-Only” site.

Hey - I’ve updated the read-only. Hopefully that works ok now.
