Is there a way to change the site title and tagline’s font? I have tried to adjust it in: Appearance -> Theme Options -> Other -> Custom CSS but it didn’t seem to accept the changes.
I am also not clear what the difference between editing CSS in this section vs. editing it in Appearance -> Edit CSS?
Change the font family in the above code to what you want to use.
I have used this CSS code on my test site and it worked fine for me.
I have tried to adjust it in: Appearance -> Theme Options -> Other -> Custom CSS but it didn’t seem to accept the changes.
What CSS code have you added in the Custom CSS option and what do you mean by "it didn’t seem to accept the changes"?

Both are same and do the same work but the only difference is that Custom CSS option is provided by the Travelify so that you don't have to use any other plugin to use this option. The Edit CSS option is provided by some plugin that you are using on your site like Jetpack plugin and its custom CSS module.
