How can this be done in API Dog?
If you hide the Title from the settings, it will remove it from all places by default. If you only want to hide it in the UI, you can use custom CSS—it looks like you’ve already figured that out.
Cool alright thanks! 
You can first set the global font in the settings, then apply a specific font style to the heading elements separately.
Okay let me try that and get back to you, thanks
Thanks, I got it working
