Gutenberg

Gutenberg is the default block-based content editor in WordPress, introduced in WordPress 5.0. It replaces the classic TinyMCE editor with a modern block-based editing experience where content is built using individual blocks for paragraphs, headings, images, buttons, tables, and more. Gutenberg makes it easier to create structured content without needing to write HTML directly. The WordPress Full Site Editing feature extends Gutenberg beyond posts and pages to allow block-based editing of the entire website including headers, footers, and templates.
