Supported Themes
You can apply two types of themes to a Web Dashboard:
- Predefined themes
- You can find the complete list in the table below. All the listed options are different modifications of the Generic, Generic Compact, and Material Design Compact DevExtreme themes.
- Custom themes
- You can modify Generic and Generic Compact DevExtreme themes. This topic includes step-by-step instructions on theme customization.
Each theme is a collection of CSS files (stylesheets).

Apply a Built-in Theme
Use the CSS files that correspond to the predefined theme you want to apply. The code snippet below shows how to enable the Carmine theme:
@import url("../node_modules/ace-builds/css/ace.css"); @import url("../node_modules/ace-builds/css/theme/dreamweaver.css"); @import url("../node_modules/ace-builds/css/theme/ambiance.css"); @import url("../node_modules/devextreme/dist/css/dx.carmine.css");@import url("../node_modules/@devexpress/analytics-core/dist/css/dx-analytics.common.css");@import url("../node_modules/@devexpress/analytics-core/dist/css/dx-analytics.carmine.css");@import url("../node_modules/@devexpress/analytics-core/dist/css/dx-querybuilder.css");@import url("../node_modules/devexpress-dashboard/dist/css/dx-dashboard.carmine.css");Customize Themes
Warning
Customization is available only for Generic and Generic Compact themes.
The DevExpress Dashboard CLI is used with the DevExtreme ThemeBuilder to create a custom theme for the Web Dashboard.
Theme customization involves the following basic steps:
- Use the DevExtreme ThemeBuilder tool to customize an existing theme and export the results.
- Add Dashboard-specific settings to the generated resource files.
- Use the DevExpress Dashboard CLI to convert the customized resource files into a Web Dashboard theme.
- Register the new theme in your application.
Create a Custom Theme
- Make sure you have Node.js and npm installed on your machine.
- Open the ThemeBuilder. Create a custom theme based on Generic themes. For instance, you can use the Light theme as a base and change its accent color from blue (#337ab7) to yellow (#fdb400).
- Set the color scheme name (for example, “light-yellow”) and use the Export Metadata → Download Metadata File button to export metadata in a JSON format.
- Copy the downloaded JSON file (dx.generic.light-yellow.json) to an empty folder.
Edit dx.generic.light-yellow.json and add the dashboardItems property to override the accent colors at the dashboard level:
{ "items": [ { "key": "@base-accent", "value": "#fdb400" } ], "dashboardItems": [ { "key": "@dashboard-item-selected-bg", "value": "rgba(#fdb400, 0.2)" }, { "key": "@dashboard-item-hover-bg", "value": "rgba(#fdb400, 0.1)" } ], "baseTheme": "generic.light", "outputColorScheme": "light-yellow", "makeSwatch": false, "version": "23.2.5", "widgets": [], "removeExternalResources": false}Refer to the Color Constants section to see a list of available color constants you can use to customize Web Dashboard colors.
In the folder you created in Step 4, execute the command that installs the
devexpress-dashboard-clipackage and builds the CSS files for your custom JSON file. Use the same version of thedevexpress-dashboard-clipackage as the version of DevExpress packages that you use in your application:npx devexpress-dashboard-cli@23.2.5 build-theme --input-file dx.generic.light-yellow.jsonThis generates the following CSS files and their minified versions:
- dx.light-yellow.css
- dx-analytics.light-yellow.css
- dx-dashboard.light-yellow.css
- dx.light-yellow.min.css
- dx-analytics.light-yellow.min.css
- dx-dashboard.light-yellow.min.css
Warning
The
devexpress-dashboard-clipackage version should match the version of other DevExpress packages used in your application. To check the version for which you generated the CSS files, open thedx-dashboard.<theme-name>.cssfile and find the version number in the comments.

The Web Dashboard uses color constants to paint the control’s elements. The colors of the color constants listed in the table below can be customized. Changes to specific dashboard elements’ colors do not affect the basic DevExtreme colors.

Apply a Custom Theme
A custom theme’s icons should be in the same folder as the theme’s CSS files. The icons folder is located in the node_modules/devextreme/dist/css directory. Copy the icons folder to the directory that contains your custom theme.
To apply a custom theme, register the generated CSS files instead of the default styles.
Create the custom-css folder in the project and put the generated CSS files in the created folder. Open the index.css file and replace corresponding existing CSS files with the generated ones:
@import url("../node_modules/ace-builds/css/ace.css"); @import url("../node_modules/ace-builds/css/theme/dreamweaver.css"); @import url("../node_modules/ace-builds/css/theme/ambiance.css"); @import url("custom-css/dx.light-yellow.min.css");@import url("../node_modules/@devexpress/analytics-core/dist/css/dx-analytics.common.css");@import url("custom-css/dx-analytics.light-yellow.min.css");@import url("../node_modules/@devexpress/analytics-core/dist/css/dx-querybuilder.css");@import url("custom-css/dx-dashboard.light-yellow.min.css");The image below shows the Web Dashboard with the custom Light Yellow theme:
