In 2016 at WordCamp US in Philadelphia, PA, Matt Mullenweg announced to the world that a new post and page editor would be coming to WordPress. “The editor does not represent the core of WordPress publishing,” Mullenweg said.
His vision of the editor was geared towards a more block-based approach that unifies widgets, shortcodes, and other areas of WordPress. Today, that vision has become a reality with the release of WordPress 5.0 featuring project Gutenberg.
The New Editor in WordPress 5.0
Instead of a large blank canvas, content is broken up into a series of individual blocks that are independent from the content as a whole. For example, you can edit the HTML of one block without it affecting other blocks.
The editor comes with more than 16 blocks to add content. You can add more blocks by installing and activating plugins.
Some of the Blocks That Are Available in WordPress 5.0
Each block typically has two areas where you can manipulate its content. The Toolbar, which displays when hovering over a block, and the Inspector located in the right-hand sidebar. The Inspector houses less-often used settings that require more screen space.
