 DevExtreme Application Templates include two default themes: `base` and `swatch`. This example implements a DevExtreme [SelectBox](https://js.devexpress.com/Documentation/ApiReference/UI_Components/dxSelectBox/) designed to switch between themes at runtime.
 
-Our Application Templates contain SCSS variables that allow you to change theme colors. You can also use our predefined [CSS classes](https://js.devexpress.com/Documentation/ApiReference/UI_Components/CSS_Classes/) ([dx-theme-background-color](https://js.devexpress.com/Documentation/ApiReference/UI_Components/CSS_Classes/#dx-theme-background-color), [dx-theme-text-color](https://js.devexpress.com/Documentation/ApiReference/UI_Components/CSS_Classes/#dx-theme-text-color), etc.) to style native HTML elements to maintain a consistent look across your application.

 To switch between themes, use StyleSheet APIs to disable all loaded `base`/`swatch` stylesheets (excluding the active stylesheet) and update SCSS variables. Refer to the following files to review framework-specific implementations:
 - [Angular Theme Service](Angular/src/app/shared/services/theme.service.ts)
 - [Vue Theme Service](Vue/src/services/theme-service.ts)
 - [React Theme Service](React/src/contexts/theme.tsx)
