Add a responsive ad in header

Hi,

Fantastic theme!

I’m playing around with it at the moment. How can I add a responsive google ad in the site header?

There is an option to align the logo left. Custom modifications might be necessary I know, to the header.php and style.css and also be removed to adjust to screen sizes.

I don’t know if this questions was posed before. Do you have an answer to this?

Thanks!
