Hi James,
Thank you for your response.
My original goal is “change font family of site title and body”.
It’s my steps.
1. add embed standard sentence like “<link href=”https://hogehoge…..” to header.php
2. add font family in theme customization.
And font family for body is all OK.
But site title is not change.
Next I use plugin “Google Fonts Typography” you recommended.
It seems it’s ok the review of theme customization, but don’t fix it.
Best Regards,
