Bootstrap Theme Overview

The KendoReact Bootstrap theme is part of the KendoReact library of React UI components. It is distributed through NPM under the kendo-theme-bootstrap package.

Compatibility with Bootstrap Framework

Starting with v4.40.0, the Kendo UI Bootstrap theme is based on Bootstrap v5.

There are many changes and tweaks between Bootstrap v4 and Bootstrap v5, with the most noticeable being in the colors. To revert, somewhat, to previous look and feel, we provide color swatches for Bootstrap v4 and even Bootstrap v3. They are included in kendo-themes GitHub repository.

Note: Bootstrap uses semantic versioning, which means that Kendo UI Bootstrap theme is no longer compatible with Bootstrap 4 and will throw errors when compiled against Bootstrap 4. More information about the migration process and changes could be found in kendo-themes GitHub repository.


  1. Download and install the Kendo UI Bootstrap theme package.

    npm install --save @progress/kendo-theme-bootstrap
  2. For the next steps that include alternative approaches for theme installation, refer to the instructions in the article on styling in Kendo UI.

If you include the Bootstrap framework from its source, you have to add kendo-theme-bootstrap and any variable customizations before you import the Bootstrap framework.

  // Set the variables here.
  @import "~@progress/kendo-theme-bootstrap/dist/all.scss";
  @import "~bootstrap/scss/bootstrap.scss";


To apply the Bootstrap theme to any of the examples on this website, use the theme chooser drop-down at the top-right corner of the example. The Material theme styling is loaded by default.

To simultaneously preview multiple components from different packages, to build your own theme, or to customize any of the available Kendo UI ones, use the capabilities of the Kendo UI Theme Builder web application.
