Moving logo down

Hello, all.

I’m needing some help with the wordpress page I’m setting up – https://mychristina.com.br/

What I am trying to do is moving the logo down so it ends right on top of the menu. I’ve tried some CSS codes I’ve found here but none of them seem to make any difference. The theme I’m using is Colormag.

Also – don’t know if this is the place to ask, but whenever I try the address with “www.”, it doesn’t lead to my site, but to a Hostgator coming soon page. Is that normal?
