Gutenberg offers minimal styling options for the elements. You can adjust the font size, color, and background color. But apart from these, there aren’t many options you can tweak. Nonetheless, they’re useful and nice to have, but it would be great if more were available. For example, I would have loved to be able to adjust the font family of the content I added. Unfortunately, Gutenberg offers no way to do that, it can only inherit it from the theme.
