The Syncfusion React Bootstrap theme is designed based on the Bootstrap v3, whereas the Bootstrap 4 theme is designed based on Bootstrap v4. In addition to these built-in themes, the ThemeStudio provides support for the Fusion Theme that can only be downloaded from the ThemeStudio.

Reference themes in the React application

Using the following approaches, the themes can be referenced in the React application,

  • npm packages - Used to customize the existing themes and bundle stylesheet in an application.
  • CDN - Used to refer complete css via static web assest.
  • CRG - Used to generate resources only for the selected (used) components.
  • Theme Studio - Used to customize and generate themes only for the selected (used) components.

Instead of using the CDN reference, use the npm packages reference in your projects to customize the theme or bundle it with the other style sheets.

Refer themes through npm packages

Themes are shipped as individual and combined CSS files. The combined CSS file can be referred from the npm package @syncfusion/ej2 and individual CSS files are available within the same component repository’s style folder. In ej2 npm packages, we have shipped both CSS and SCSS files for all components.

To use the combined CSS files, install the npm package using the following command

Copied to clipboard
 npm install @syncfusion/ej2

Referring all components CSS

Copied to clipboard
@import "./node_modules/@syncfusion/ej2/<theme_name>.css";

Referring all components SCSS

Copied to clipboard
@import "./node_modules/@syncfusion/ej2/<theme_name>.scss";

Referring to individual component theme

You can get the individual theme from the individual package or from ej2 package.

Referring to individual component from the individual package

Copied to clipboard
@import "<dependent-package>/styles/<theme_name>.scss";
@import "ej2-react-buttons/styles/button/<theme_name>.scss";

Example:

Copied to clipboard
@import "ej2-base/styles/material.scss";
@import "ej2-react-buttons/styles/button/material.scss";

The ej2-base is a common dependent package for all Syncfusion React component styles. So, it needs to be added first in the import statement.

Referring to individual component from the ej2 package

Copied to clipboard
@import "ej2/<dependent-component>/<theme_name>.scss";
@import "ej2/button/<theme_name>.scss";

Example:

Copied to clipboard
@import "ej2/base/material.scss";
@import "ej2/button/material.scss";

Advantages of individual components theme

  • Reducing the page load time of application
  • Reducing bundling size
  • Avoid unused CSS

Refer themes through CDN reference

Instead of using a local resource on your server, use a cloud CDN to reference the theme style sheets.

Syncfusion React Themes are available in the CDN. Make sure that the version in the URLs matches the version of the Syncfusion React package you are using.
