Attributes for Blocks vs Content Blocks Builder – Create blocks, repeater blocks with carousel, grid, popup layouts

This plugin adds additional advanced inspector controls to Gutenberg blocks that allow to add any custom HTML attributes to the block’s front-end output. This allows you to add inline styles to fine-tune the block’s appearance, set aria attributes to improve your site’s accessibility, add data attributes to integrate with any JavaScript modules or even JavaScript DOM event attributes such as onclick, onchange or onload.

Content Blocks Builder (CBB) helps you create custom blocks, variations, styles, and patterns — directly in the Block Editor without touching a code editor. The WordPress Block Editor (Gutenberg) is a solid foundation for building websites. But when you need more specific layouts or custom functionality not available in default blocks, you’re often forced to write custom code or rely on bloated third-party plugins. CBB solves this by letting you visually group core or third-party blocks into flexible container blocks — right inside the native Block Editor. These container blocks support native features like typography, spacing, colors, borders, plus advanced features from CBB that help you build layouts like responsive grid, slider/carousel, toggle/accordion, modal/off-canvas/popover, background effects all without writing a single line of code. You can also build repeater blocks to display repeatable content — similar to ACF repeater field type, but entirely block-based and visual. 👉 Read the detailed guide to CBB blocks.
