A: Hey Matthias,

Thanks for your question. Google Fonts do not load by default. They only load if you select "Google Font" from the font-family menu and then choose a Google font in the new field that displays. If you only enter the names of fonts in the font-family field (e.g. Arial), Microthemer will assume the font is a system font, or a custom font that is already loaded - even if you enter the name of a Google font (e.g. Oswald).

I hope that helps. Please let me know if you have any other questions.

Thanks,
Sebastian
