Sass Theme Builder

Progress Sass Theme Builder for Kendo UI is an Angular web application that enables you to create new or customize existing themes.

The tool renders the same look and feel as the look and feel of all other components in the suite. It also delivers full control over the skin elements of each component and automatically updates its composite units. After you create the skin and achieve the desired look of the theme, the Sass Theme Builder enables you to download and integrate it in your project.

  4. (Optional) After the initial selection, add or remove elements for customization.

To deliver the full set of their functionalities, some Kendo UI controls, such as the Grid, have composite structures and include child components. In such cases, the Theme Builder automatically applies the theme modification to the child components and you do not need to customize each of them separately.

Customizing Existing Themes

The Sass Theme Builder supports the following options for customization:

  • Color pickers which customize the appearance of the components.
  • The Apply changes instantly option which enables you to observe the changes on the fly.
  • Manual updates of each component element.
  • Utilization of predefined color swatches.

Functionalities for Customization

To customize an existing theme, use the following Sass Theme Builder functionalities:

  1. Color Swatches—Contains predefined color palettes that you can apply to all components in your application.
  2. Default—Provides the applicable color customization options.
  3. Preview Components—Keeps the main view of the components. It reflects the customization changes you make each time you add or remove theme elements.
  4. Download—Downloads the archive that holds the generated style files after the customization completes. When you click the button, a dialog appears and prompts you to name your theme.
