PublishPress Blocks is a plugin that adds over 20 extra blocks to the Gutenberg interface, along with custom layouts, CSS styles, and permissions for blocks.
There are many Gutenberg plugins available, but PublishPress Blocks is different. This plugin has a strong focus on being useful for publishers and content creators.
If you want to see an example of this content focus, check out the Content Display block. This really is the best way to show your content in a block.
