Increase the logo

Hello!

Thank you for the beautiful theme! What I am trying to do is to make the logo bigger. No matter what image I place there and how big it is, it stills show up very small. I tried different additional CSS Codes, but non of them worked. It just doesn’t change.

Is there anything I could do in order to make it appear bigger?

Thank you!
