WordPress Block — What Is a Gutenberg Block?

WordPress blocks are the fundamental building units of the Gutenberg editor. Each block is a standalone content unit — from paragraphs to complex layouts.

Definition

A WordPress block is a standalone content unit in the Gutenberg editor. Technically, each block is an HTML comment wrapper (...) with optional JSON attributes. WordPress Core ships with 90+ standard blocks — from core/paragraph to core/cover.

Block types and namespaces

Blocks follow a namespace format: `core/paragraph` (WordPress Core), `acf/hero` (Advanced Custom Fields), or `divi/text` (Divi). Plugins register their own blocks in their namespace. anipage.io generates exclusively `core/*` blocks for maximum compatibility without plugin dependencies.

Blocks vs. Classic Editor

In the Classic Editor, content is stored as a plain HTML string. Gutenberg blocks add structured metadata: each block has known attributes (align, backgroundColor, fontSize) that WordPress and tools like anipage.io can read and write programmatically.

AI generation of blocks

anipage.io generates valid Gutenberg block markup directly from a text description. The result can be imported into WordPress without post-processing. Supported blocks: Paragraph, Heading, Image, Columns, Cover, Quote, List, Group, Separator, Buttons, and more.

Frequently Asked Questions

How do core blocks differ from plugin blocks?

Core blocks (core/paragraph, core/image, etc.) are built into WordPress and require no plugins. Plugin blocks (e.g. from Elementor or Divi) require the respective plugin.

Can I transfer blocks between WordPress installations?

Yes. Gutenberg blocks are stored as HTML in the database and can be transferred via export/import. anipage.io exports work on any WordPress installation.

How many core blocks are there in WordPress?

WordPress Core ships with 90+ standard blocks. Add pattern libraries and countless plugin blocks on top of that.
