Gutenberg is WordPress’s “block editor”, and introduces a modular approach to modifying your entire site. Edit individual content blocks on posts or pages. Add and adjust widgets. Even design your site headers, footers, and navigation with full site editing support.
Each piece of content in the editor, from a paragraph to an image gallery to a headline, is its own block. And just like physical blocks, WordPress blocks can be added, arranged, and rearranged, allowing users to create media-rich content and site layouts in a visually intuitive way — and without workarounds like shortcodes or custom HTML and PHP.
We’re always hard at work refining the experience, creating more and better blocks, and laying the groundwork for future phases of work. Each WordPress release includes stable features from the Gutenberg plugin, so you don’t need to install the plugin to benefit from the work being done here
Enabling the plugin gives you early access to experimental features not yet released in WordPress Core.
