The Gutenberg block editor presents an easier way to edit your pages and posts. Learn more about pages and posts here.
The first block is the title. By default, the next block is a paragraph block. However, you can add a different block by clicking on the "Add block" (+) button, which appears at the left of any empty block, at the top left of the editor, and at the top or bottom center of an existing block.
Each block comes with its own unique toolbar, which appears on top of the block. Apart from the toolbar, each block can also have its own block settings, which appear in the right column of your edit screen.
You can drag blocks around by clicking and holding the grid icon near the top-left corner of each block, or by using the up and down arrows.
Each post and page contains a Document Settings module in the right column of the editor screen. This is where you can add tags and categories, choose a featured image, see and change the status of your post, and more.
