Content Blocks Builder


Content Blocks Builder (CBB) is a tool that helps you create your own custom blocks, variations, styles, and patterns directly in the Block Editor without using a code editor.
Unlike other page builders and block library plugins, CBB does not include a library of customized blocks. CBB uses core blocks and enhances them by adding the ability to group them into a container block that has native features like typography, colors, spacing, border, etc., and a bunch of custom advanced features. You can create common layouts such as grid, carousel, accordion, modal, off-canvas, etc. You can also create repeater blocks to display repeating content that works similarly to the ACF repeater field. For more information, please check out the detailed guide about CBB blocks.
The goal of CBB is to help you build a complex website with WordPress using only core blocks and native Gutenberg features with any block theme. You don’t need a custom theme, a feature-rich theme, or a block library plugin.

Key Features

  • Manage custom blocks: Create, edit, copy, import, and delete your own custom blocks.

  • Enhance the Query Loop block: Add grid, carousel layouts, and advanced filter and sorting settings.
  • There is a library of pre-built blocks, variations, styles, and patterns

  • Import/export custom blocks, variations, and patterns from/to other sites

Why do we create this plugin and why will you need it?

WordPress with the Gutenberg Block Editor is a powerful page builder. It comes packed with lots of blocks that you can use on your site. However, sometimes you may need something more specific or unique for your website that is not available in the default blocks or the plugins that you have installed. Or you may not want to install a bloated-block plugin library just to use a few of them. This plugin helps you create those unique layouts and features.
Based on our experience in developing hundreds of client websites with the “classic” workflow using meta field frameworks and custom theme/plugin development, we created this plugin to help us transition to the new workflow in the Gutenberg era with custom blocks, block themes, and full site editing. With CBB, you don’t have to spend time with PHP/React building custom blocks, custom themes, or plugins. Most of the tasks can be done just by using the default Editor. As a result, it will make the process of building websites simpler and more enjoyable.

Below is a video tutorial that demonstrates how you can use this plugin to design your site directly on the Editor:

How does it help?

Create custom layouts

You can create common layouts with CBB such as grid, carousel, accordion, and vertical stack. CBB includes 5 built-in layout blocks: Advanced Group, Grid, Carousel, Stack and Accordion. You can use them or build your custom blocks easily.

Create popup, off-canvas, and toggle content

With the toggle content feature, you can build a popup, off-canvas, toggle content easily and you can put anything in there.

Enhance the Query Loop and other blocks

CBB provides a bunch of advanced features to add style to custom blocks like responsive width, height, spacing, border, box-shadow, transform, alignments etc. And by wrapping around other blocks, you can add those features to other blocks as well.

Google Fonts

This feature does a really simple job, it loads a font for headings text and another for the body text from more than 1000+ Google Fonts easily with a few clicks. If you are worried about GDPR compliance, there is an option to load fonts from Bunny Fonts instead of Google Fonts.

Where is the demo?

Please check out the Design Library of templates/patterns created only by this plugin and the TwentyTwentyTwo theme without any custom code.

Which theme should I use with this plugin?

It is compatible with all Gutenberg-ready themes, but our recommended themes are default themes such as Twenty Twenty Four, Twenty Twenty Three, Twenty Twenty Two, or Astra theme.

How does it work with other blocks/plugins?

This plugin works with all third-party blocks but we recommend using single-block plugins for lightweight and performance. We also develop several single block plugins, that work great with this plugin, please see them in the below section.

Design library

We have already included a library of block patterns for you to quickly use or customize to fit your design. There is a popup inserter in the block editor for you to find and insert patterns with a few clicks.

How to use the pattern inserter popup.

Browse the Design Library to see what the plugin can do for you.

Block and Variation library

Besides the pattern library, we have built an external library of content blocks and common block variations. All of the blocks/variations in this library have been created by CBB directly in the Block Editor. With a few clicks, you can easily import blocks or variations into your site. You use them directly or customize or learn from them.

Watch some video tutorials to learn how to use the library:

Import the particles background block.
Import the basic header block.
Import the Query Loop variations.

From what I saw and tested so far this plugin seems really amazing! Apparently it's exactly what I needed for my projects. Keep up the good work and let's wait for good news.

Really an excellent plugin, that provide grid, carousel, accordion, modal popup, canvas offset and more. But its not a block library, it giving just some very basic blocks to create any kind of custom blocks we want, plus the best part is that we can even create variations of the blocks, also for the default blocks like button and cover. One more thing, it providing library of pre-build patterns, to directly insert and modify as per your need In one word this is a kind of plugin, that anybody can have love at first sight.
