Bootstrap Blocks


Bootstrap Gutenberg Blocks for WordPress. This plugin adds Bootstrap components and layout options as Gutenberg blocks.


  • Supports Bootstrap v5 and v4
  • Support for CSS grid (experimental)
  • Fully customizable with filters
  • Configuration via option page or programmatically with constants
  • Block templates can be overwritten in your theme

The full documentation of this plugin can be found on GitHub:

Available Blocks



  • Fluid: If enabled the container will use the full available width, spanning the entire width of the viewport.
  • Fluid Breakpoint: Used to enable responsive containers. This feature only works with Bootstrap v4.4+. The container will use 100% of the width until the specified breakpoint is reached, after which the defined max-widths will apply for each of the higher breakpoints.
  • Margin After: Define a margin which should be added after the container.



  • Template: Choose from a predefined template for the inner column blocks.
  • No Gutters: Disable gutters between columns.
  • Alignment: Horizontal alignment of inner column blocks.
  • Vertical Alignment: Vertical alignment of inner column blocks.
  • Editor stack columns: Displays stacked columns in the editor to enhance readability of block content.
  • Horizontal Gutters: Size of horizontal gutters.
  • Vertical Gutters: Size of vertical gutters.
  • CSS Grid Gutters: Size of gutters when CSS grid is used.



  • Sizes for all breakpoints (xxl, xl, lg, md, sm, xs): How much space the column should use for the given breakpoint.
  • Equal width for all breakpoints (xxl, xl, lg, md, sm, xs): If enabled column will spread width evenly with other columns.
  • Background Color: Set background color to column.
  • Content vertical alignment: Align content vertically in column. This option is only needed if a background color is set. Otherwise use the Alignment option of the outer row block.
  • Padding: Define padding inside the column.



  • Style: Choose the styling of the button.
  • Open in new tab: Choose if link should be opened in a new tab.
  • Rel: Set rel attribute of the link.
  • Alignment: Horizontal alignment of the button.

Supported Bootstrap versions

This plugin supports Bootstrap v4 and v5.

The version can be selected in the plugin settings (Settings > Bootstrap Blocks) or by defining the WP_BOOTSTRAP_BLOCKS_BOOTSTRAP_VERSION constant in the wp-config.php file:

  • Bootstrap 4: define( 'WP_BOOTSTRAP_BLOCKS_BOOTSTRAP_VERSION', '4' );
  • Bootstrap 5 (default): define( 'WP_BOOTSTRAP_BLOCKS_BOOTSTRAP_VERSION', '5' );

Possible values right now are '4' or '5'. By default Bootstrap version 5 is selected.

CSS Grid

The CSS grid (supported with Bootstrap >= 5.1.0) can be enabled in the plugin settings (Settings > Bootstrap Blocks) or by defining the WP_BOOTSTRAP_BLOCKS_ENABLE_CSS_GRID constant in the wp-config.php file:


When the CSS grid is enabled the row and the column blocks will use custom templates for the rendering process:

  • Row: row-css.grid.php
  • Column: column-css-grid.php

The support is still experimental since it’s also marked as experimental in the Bootstarp library. Please read the official Bootstrap documentation to get more information on how to use it.

Bootstrap library

Please be aware that this plugin does not include the Bootstrap library in your website. You need to do this by yourself. We decided not to include the library so that you can modify Bootstrap to your own needs before loading it.

You’ll find an example how to include it in your theme’s functions.php in the documentation.


All blocks are implemented as dynamic blocks. This makes it possible to overwrite the template of a block in your theme.

To overwrite a block template create a folder called wp-bootstrap-blocks/ in your theme directory. You can copy the original template from wp-bootstrap-blocks/src/templates/<blockname>.php as a starting point and adjust it to your needs.


  • WordPress >= 5.0
  • PHP >= 5.6

Which versions of Bootstrap are supported?

This plugin supports Bootstrap v4 and v5.

Is Bootstrap included?

No. This plugin doesn’t load the Bootstrap library for you. You have to do this by yourself in your theme. Please read more about this in the documentation.

This is an excellent plugin. All the pains of trying to solve web responsiveness with Gutenberg can thrown out of the window. Great compatibility with themes that already use Bootstrap for basic website structure. It took me a year of casual looking around before I found this gem. It needs to be seen mooooar!
This plugin is exactly what I wanted because I use Bootstrap to make grid and organise content on posts and pages. Fantastic, keep good work.

Very good plugin for providing container, row and column functionality for custom Bootstrap themes (my use-case). This is so much better than the default Wordpress columns. Just what I was looking for. Thanks for the plugin. 🙂
And you have all the foundations you need for building quick, bespoke, and easy-to-manage websites for your clients. I’ll be using this for all my projects from now on. Using ACF Pro to build the custom blocks required, and using these very handy container/row blocks to place my custom ACF blocks inside of. Just perfect.
