Adding custom fonts
👉Tip: Any fonts already installed in your Shopify theme or site's CSS automatically works with Builder and Builder Theme Studio–you do not need to add them separately.
To add custom fonts in Builder:
Navigate to account/organizations.
Select the pencil icon next to Custom fonts.
Give your custom font a name, upload the font file, and select the Save button.
In the Style tab, in the Typography section, find your custom font in the Font dropdown.
