Font - title of site - make consistent?

Hi - love this theme but was wondering how it might be possible to change the font of the title of the site (displayed in the header) so that it is consistent with posts (or generally, how do you specify that font)? Would this also affect the font face of the menu coming from the header?

Website title is set to Open Sans just like the theme content.

If you have changed fonts via Theme Options or otherwise you can define them by adding the same font-family for website title as well. You can add this code to Theme Options - Other - Custom CSS

.navbar-brand {
    font-family: Arial;

Of course change font accordingly.
