The answer to both questions is, yes! The Gutenberg editor is available as a plugin and can be installed at any time with just a few clicks. All of the WordPress themes offered by IONOS are compatible with the Gutenberg editor. Try it out and enjoy using WordPress even more easily and comfortably than before. Install posts and pages or build a whole new website, shaping your online site to your needs and requirements. Should the Gutenberg editor not satisfy you, you can switch back to the Classic Editor at any time — or use another editor in its place, which can be just as easily integrated by plugin into your WordPress installation.
