CSS library for building beautiful and well working web UI components within Bentley Systems & iTwin.js applications.
An open-source design system that helps us build a unified web experience.
iTwinUI is a design system for building beautiful and well working web UI components within Bentley Systems & iTwin.js applications. It supports light and dark color schemes and also comes with high contrast versions of both.
iTwinUI-css consists of the following packages:
@itwin/itwinui-css - the CSS for every component as well as some global styles@itwin/itwinui-variables - CSS variables for iTwinUI's design tokensIf you're looking for React components, check out @itwin/itwinui-react which is built on top of iTwinUI-css.
Install both packages:
npm install @itwin/itwinui-css @itwin/itwinui-variables
or if using yarn:
yarn add @itwin/itwinui-css @itwin/itwinui-variables
Import the global styles and variables (only needs to be done once per page):
@import '@itwin/itwinui-variables';
@import '@itwin/itwinui-css/global';
Note: If your project doesn't support export maps, then you might need to import the css from the real paths:
@import '@itwin/itwinui-variables/index.css'; @import '@itwin/itwinui-css/css/global.css';
Apply the iui-root class at the root of your app, and use data-iui-theme to specify theme (light or dark). See @itwin/itwinui-variables/README.md for more details on theming.
<body class="iui-root" data-iui-theme="light">
<!-- your application code -->
</body>
Now you can start using our components:
@import '@itwin/itwinui-css/css/button.css';
<button class="iui-button" data-iui-variant="default">
<span>Hello world</span>
</button>
Check out our demo website for a preview of all our components.
