Is the only way to change to a custom font on the theme is to use google fonts? I need the site to be in ITC Avant Garde. Im not sure what plugin would work the best to get that font. Google Fonts doesn’t offer a close enough replacement for what my client wants. What would be the best way to get that font up on the site?
No, not at all, you can use whatever font you want with my themes. As stated in theme documentation, please follow the information in Appearance → Customize → Theme Options → Typography →“Use custom fonts”.
