Selecting fonts for text areas
For all except the Body font, you can toggle on the option to Capitalize the text. You can also set the Style from Normal to Bold.
Custom fonts
If you are unable to locate the font you need, it may be necessary to hire a developer to install a custom font for your store. For more information, check out Can I add a custom font to my theme?
