NovaFonts provides you with the ability to add and remove as many fonts as you like. To add or remove any font you must go to Appearance → Customize and click on the Nova Fonts panel.
Note: Once a font was added or removed you will need to save your changes by hitting the Publish button in the top right corner of the customizer to make your changes permanent.
Note: Theme authors can disable the ability to add or remove fonts and thus this functionality might not be available to you at times.
Within the Nova Fonts panel, near the top, you will find a text input field and a button saying Add New. For your own reference, enter a name (e.g. Headings) into the text field and click on the Add New button next to it. The new font section will be inserted at the bottom. You can now click on the newly created font section and define it’s stylistic properties.
Click on any font section within the Nova Fonts panel and scroll all the way down to the bottom. There you will find a link saying Remove Font, once clicked the font will be remove from the panel and it’s styles from the preview. Please note, you will have to click on the Publish button at the top of the customizer for your changes to become permanent.
