Not really... it's not a common request, and I think it is still best to change it from the theme itself...
Or you can remove the font declarations altogether, from the theme, and then add them in via the Custom HTML form...
I read about the Requirejs but I couldn't make it work. Can someone point out an example that shows how to do that?
I am trying to use this one: https://github.com/jackocnr/intl-tel-input
The theme this forum is using loads pulling.js as a requirejs library
And this is the library that's loaded https://github.com/nodebb/pulling
@baris Thanks again!
