DevExtreme jQuery/JS - Theme Builder

The Theme Builder is a tool for creating custom themes based on predefined DevExtreme and Bootstrap themes. You can use it as follows:

  • Access the online version.

  • Run the local version by opening the index.html file located in the C:\Program Files (x86)\DevExpress 18.1\DevExtreme\Tools\DevExtreme\ThemeBuilder directory by default. This version is available only if you have istalled DevExtreme using the installer for Windows.

The Theme Builder divides theming settings into two groups: Basic Theming for the most frequently used settings, and Advanced Theming for more advanced and widget-specific settings.

Link this theme to your project after dx.common.css but before the DevExtreme script:

HTML
<head>
    <link rel="stylesheet" type="text/css" href="css/dx.common.css" />
    <link rel="stylesheet" type="text/css" href="css/dx.mycustomtheme.css" />
    <script type="text/javascript" src="js/dx.all.js"></script>
</head>
NOTE
Predefined themes are periodically updated and improved. We recommend saving your custom theme's metadata to avoid possible difficulties when upgrading to the latest release. Refer to the Postpone Customization topic for more details.
