How do I add custom fonts to the WP Block Editor (Gutenberg)?
For example, if I enter a heading there’s a number of fonts for me to select from the dropdown menu, but I would like to select a font from Adobe Fonts.
the Core blocks provided by WP don’t come with Font Selection options so you must be using a plugin to provide that option ? If so you would need to ask the plugin author on how to use a Custom font.
